PREFACE India Meteorological Department has a great history since its inception in 1875. Today the department has developed into a vast organization comprising of various divisions and providing services to different sections of the society. The department is involved in a variety of nation wide multi location and multiagency projects The RMCs and MCs are actively participating in various modernization plans. The forecasts & weather information provided by the department are very useful for various purposes. Since the department has offices & observatories in remote areas also the officials working there are generally unaware of the developments taking place in the various divisions of the department. In the absence of information flow to these stations they feel cut off from the mainstream. To keep all the officials / personnel of the department informed about all the activities / programs being taken up by different divisions and main centres, it has been decided to publish ‘IMD update’ regularly in alternate months (i.e., Jan, March, etc). IMD update includes the information about the programs, plans and projects under taken by different offices / divisions for modernization of IMD. It is due to concern and thereafter the inspiration of DGM to keep the entire fraternity of IMD well informed about the changing scenario in the department that lead to the publication of ‘IMD update’. It is hoped that all the personnel of the department would find it useful.

UPPER AIR INSTRUMENTS, NEW DELHI
1. Radar Section
Radar section of DDGM (UI) office is responsible for maintenance and operation of
IMD,s weather radar network.
IMD presently operates a network of eleven Cyclone Detection and 29 Storm
Detection Radars. Most of the radars of this network are very old and are based on
conventional analog systems, which are now obsolete. Moreover, their products
are incompatible with present day requirements of digital data on different
parameters which can be directly used as inputs to weather prediction models.
There has already been some progress in this regard through procurement and
commissioning of 5 Doppler Weather Radar systems on the east coast (Kolkata,
Visakhapatnam, Machalipatnam, Chennai and Sriharikota). Induction of an
adequate number of Doppler Radars in the network would facilitate improvement in
analysis. Doppler radars will give us more derived products than the conventional
radars, which are useful for weather forecasting. Some of the examples are radial
winds, precipitation rates, vertical velocity of air etc. Doppler radars are especially
useful for forecasting severe weather events, and are power full tools for
nowcasting. Under the modernization plan of IMD ,it is proposed to replace all
existing old and obsolete conventional radars with the state-of-art modem radars
having Doppler capabilities. It is proposed to install 55 S-band Doppler weather
radars in the IMD's network to bring the entire country under radar coverage. In
,the first phase of modernization plan of IMD, it is proposed to replace 12 of the
existing radars with state of art Doppler Weather Radars at Paradip, Mumbai, Goa,
Lucknow, Patna, Patiala, Mohanbari, Agartala, Bhopal, Delhi, Karaikal and Nagpur
supply order for which has already been placed on M/s Metstar, China. In addition,
it is planned to install DWRs at Bhuj (Gujrat) & Kochi (Kerala) for which order has
already been placed with M/s BEL Bangalore as part of the already approved plan
scheme of the Department.

2. Wind profiler
Under the modernization plan phase-I of IMD four numbers of wind profilers are
proposed to be procured.
Current achievements and future Dlans OF UPPER AIR OBSERVATORIES
In I.M.D. upper air observations are made at 39 RS/RW stations and 62 Pilot
Balloon observatories to provide Met data i.e. pressure, temperature, humidity &
wind at various levels in the atmosphere up to an altitude of 30-35 kms for RS/RW
and up to a maximum altitude of 18 Kms employing optical theodolites for PB
stations.
TYPES OF GROUND EQUIPMENT USED
RS/RW observatories have been equipped with three types of ground Equipment
as under:
• Radiosonde Ground equipment (ECIL/DIGITAL make) along with X band
Wind finding Radars (EEC/MULTIMET) at 401 MHz
• IMS-1500 Radiotheodolite at 1680 MHz
• SAMEER Radiotheodolite at 401 MHz
MAINTENANCE OF EQUIPMENT
6
The maintenance is carried out by HQ through spares initially procured and few
spares procured later from time to time. Recently at many RS stations operating on
401 Mhz PM broadcast from nearby AIR station is interfering with RF signals at
many RS stations. To over come this problem improved RS receivers need to be
procured. The optical theodolites are being serviced and maintained in IMD
Workshop by procuring spares from the manufacturing firm.
RECENT IMPROVEMENTS IN UPPER AIR COMPUTING SYSTEM
To eliminate manual interaction and to minimize instrument error, up-gradation of
the RS/RW computing system has been done.
(i) IMD Mark - IV radiosonde developed in-house has been implemented at all
RSRW stations. This radiosonde is being used with IMS - 1500 Radiotheodolite as
well as with new auto computation system. Plans are to completely stop the
manufacturing of MK - III radiosonde as all the RS/RW stations are now equipped
to work with MK-IV radiosonde. DDGM (SI) office has b~en requested to change
the design of their radiometersonde and ozonesonde to MK-IV so that we may stop
the manufacturing of MK -III radiosonde. The software developed. by SAMEER,
Mumbai generates Meteorological message in standard WMO format and also
gives plots of T-Phi gram, temperature and humidity profiles.
(ii) The Pressure sensor of IMD MK-IV radiosonde is a mechanical design and
needed urgent 'up-gradation for more reliable data. A solid state pressure sensor
based radiosonde was designed and tested. The software was suitably modified
and the ascents were conducted at RSRW Thiruvananthapuram. The sensor
performed satisfactorily in the full range. More ascents are planned with new bead
type thermistors to improve the data further. After the tests the modified MK-IV
would be used for observations in the network.
7
(iii) Development of hand held data loggers along with software for PB
computations has been completed under an MOD with SAMEER and implemented
at 62 stations. All the optical theodolites would be replaced with new theodolites for
improved ascents. Procurement procedures are in the final stages for 5 numbers of
electronic optical theodolites and supply order has been placed for 70 numbers of
optical theodolites.
FUTURE PLANS FOR FURTHER IMPROVEMENTS
1. It is proposed to install mini-electrolyser for generating hydrogen gas in-situ at
the RS/RW stations employing technique of electrolysis of water. It will cut down
expenditure on transportation of chemicals to the station. Electrolyser plant has
already been installed and commissioned at RMO Ayanagar, Manali and Jammu.
2. Development of indigenous MEMS sensors for IMD radiosonde is being done in
collaboration with SCL, Chandigarh in order to replace the existing sensors.
3. Development of GPS based radiosonde is under progress in collaboration with
SAMEER, Mumbai. Prototype testing is expected in September 2008. ISRO has
also developed GPS radiosonde and trial ascents have been taken at SHAR and
VSSC, one test ascent has also been taken at New Delhi and results are
encouraging. Plan, is to start regular ascents at five stations.
4. Development of 1680 MHz indigenous radiotheodolite and receiver is under
progress in collaboration with SAMEER, Mumbai.
5. Ten upper air stations are being up graded by installation of GPS system, five
under MFI and five IMD procurement, order has been placed.
8
6. As a step for improvement of data quality a scheme for taking ascents with
Sippicon radiosonde at ten stations with IMS radiotheodolite is under consideration
at IFD, MoES to accord approval for procurement on PAC basis.
7. Development of 1680 MHz MMIC transmitter for IMD radiosonde is under
progress in collaboration with GAETEC, Hyderabad. Prototype expected to be
ready within two months.

Extended Range Forecast System (ERFS) Project
A program on development and application of ERFS for Climate Risk Management
in Agriculture has been initiated by Ministry of Agriculture. It is a national
coordinated program to be funded by the Department of Agriculture and
Cooperation (DAC), Ministry of Agriculture. The major objective in this program is
to develop a forecast system to provide seasonal monthly scale prediction of
precipitation and surface air temperature during the monsoon season as well as
other seasons over meteorological subdivisions/agro-climatic zones in India for its
use in agricultural sector and for other end-users. It is envisaged that about 12
national agencies (IMD, IITD, NCMRWF, DAC, ICAR, SAC, IITM etc.) and a
number of leading international organizations will be associated with the
development of ERFS for India. The Ministry of Agriculture has constituted a
Project Implementation Committee (PIC) on ERFS under the chairpersonship of
Secretary, Department of Agriculture and Co-operation (DAC) in which DGM, IMD
is the co-chairman. The Scientific and Technical Committee (STC) is headed by
Prof. U.C. Mohanty, IIT Delhi and ADGM(S), Dr. L.S. Rathore, Head, Agrimet are

National Satellite Meteorological Centre
• At present two Indian Geostationary Satellites, namely KALPANA-I and
INSAT-3A are operational at 740 E & 93.50 E Longitudes respectively for
meteorological purposes. The NSMC also uses another satellite INSAT-3C
for communication purposes.
• A dedicated Meteorological Satellite KALPANA -1 was launched by India in
September 2002 having three channels Very High Resolution Radiometer
(VHRR) for cloud imagery in Visible (0.55-0.75 micrometer), Infrared (10.5-
12.5 micrometer) and Water Vapor (5.7-7.1 micrometer) and a Data Relay
Transponder (DRT) for receiving the data from Automatic Weather Stations
(AWS). 125 nos. AWS stations are now operational with Kalpana-1 satellite.
• INSAT -3A was launched in April, 2003 by India with a 3 channel VHRR
(Visible, Infrared and Water Vapor) similar to Kalpana-1 and a Charged
Coupled Device (CCD) camera (Visible, Near IR and SWIR) for cloud
imagery and a DRT payload for collection of meteorological and hydrological
data from automatic weather Stations. Both these satellites are working
satisfactorily and are being operationally used for meteorological
applications. Satellite Meteorology Division (now NSMC) of India
Meteorological Department (IMD) performs the reception and processing of
above satellite’s data. The Images in all channels and the derived products
are updated on IMD website as well as supplied to various users.
• The S - band broadcast capabilities of INSAT – 3C is being used for Digital
Meteorological Data Dissemination (DMDD) and Cyclone Warning
Dissemination System (CWDS). A network of 37 nos. DMDD stations is
operational at RMCs/MCs for receiving satellite imageries and synoptic data
and analyzed weather charts. (Annexure-II). It is also planned to install
DMDD stations at Nepal, Srilanka and Male shortly.
23
• A network of 353 CWDS (252 analog and 101 Digital) stations is operational
along the east and west coast of India for warning the coastal regions in
their local language in case of cyclones approaching those areas. The state
wise installations of CWDS/DCWDS is enclosed at Annexure-I.

5. Issuance of District-Scale Quantitative Forecasts
As a major step towards downscaling forecasting activities, IMD has initiated the
project of issuing district scale quantitative forecasts for all 586 districts of India.
Under this project, quantitative weather forecasts are issued for the Weather
parameters of daily Weather Forecast - Maximum/ Minimum temperature, rainfall,
31
maximum & minimum temperatures (Trend). Total cloud cover, surface relative
humidity (0200 & 12UTC) and surface wind (00 & 12 UTC) 5 days in advance.
These forecasts are generated through a multi-model ensemble system. The
system consists of dynamical models, viz. European Centre for Medium Range
Weather Forecasting (ECMWF) at 25 km resolution, National Centre for
Environmental Prediction (NCEP) at 1º x 1º Lat./Long. resolution and Japan
Meteorological Agency (JMA) at 1.2 x 1.2º Lat./ Long. resolution. Each model
output is converted into uniform 25 km resolution and weight for each model at
each grid is computed. The models used in this scheme are the state of the art
global models from the leading global NWP centres. The ensemble output is
generated at 25 km resolution and district rainfall is computed by averaging the
grid point values falling over a particular district. These forecasts are available on
the national website of IMD.
6. WRF Model runs, at other centres
As a follow up of the 1st plan review meeting recommendations, many forecasting
centres of IMD have started running the WRF model on trial basis.

National Climate Centre / Long Range Forecasting Unit
The National Climate Centre (NCC), Pune has been providing various climate
related services to the country, since 1985. The centre has been carrying out many
India specific climate related activities like Climate Monitoring and Analysis,
Climate Prediction (Seasonal Forecasts), Climate Data Management and Climate
Research. NCC is bringing out climate diagnostic bulletins regularly and different
climate data products are prepared for the user community. Operational Seasonal
forecast for rainfall over the country is another important activity of the NCC. As a
part of recent major modernization activities undergoing in IMD, efforts are going
on to widen the activities of the centre so that in the near future it can cater the
needs of the entire south Asian region. Brief information regarding the present
activities and future plans of the centre is provided here.
The present activities of the NCC
(i) Climate monitoring and analysis : Prepares and publishes monthly,
seasonal climate diagnostic bulletins and annual climate summaries for the Indian
region regularly. Detailed special monsoon reports are also being published every
year. The diagnostic bulletins provide brief account of the main weather and
climate feature during the period of analysis.
(ii) Long and extended range forecasts : Prepares long range forecasts for
winter (Jan- March) precipitation, monsoon season (Jun to Sept) rainfall and
northeast monsoon (October-December) rainfall. The main approach used for
preparing these forecasts is statistical method. Since 2003, IMD issues long range
forecast for the south-west monsoon rainfall in two stages. The first stage forecast
is issued in mid-April and the second stage forecast is issued by the end of June.
35
The first stage forecast consists of quantitative forecast for the seasonal (June to
September) rainfall over the country as a whole. The second stage consists of
update for the forecast issued in April, a forecast for July rainfall over the country
as whole and forecasts for seasonal rainfall over four broad rainfall homogeneous
regions of India viz, Northwest India, Northeast India, Central India and South
Peninsula. By 15th May, IMD also issues a forecast for the southwest monsoon
onset over Kerala using an indigenously developed statistical model. Recently the
centre has started preparing 5-20 days experimental forecast of outgoing long
wave radiation distribution over Indian region during monsoon region based on
analog method. The OLR forecast can be used for predicting the intraseasonal
variation of monsoon rainfall.
At present, the forecast for the southwest monsoon season rainfall over the country
as a whole is issued using the new statistical forecasting system based on the
ensemble method introduced in 2007. In this new ensemble forecasting system a
set of 8 new predictors were used. For the first stage forecast of seasonal rainfall
over the country as a whole, 5 predictors are used and for the update forecast 6
predictors are used. The forecast for the July rainfall over the country as whole and
that for the seasonal rainfall over the four homogeneous regions are based on
multiple regression method using separate set of parameters.
The existing operational long range forecasting system of IMD is based on the
statistical models. However, looking at the potential of dynamical models, IMD has
also implemented an experimental prediction system based on dynamical models.
For this purpose, IMD has adapted a dynamical model (Atmospheric General
Circulation Model) developed at the Experimental Climate Prediction Centre
(ECPC), Scripps Institute of Oceanography, USA.
(iii) Data services and Climate data products : IMD has long time series of
various climate data in its archive. Data rescue and data services are mainly
provided by National Data Centre (NDC) at Pune. NCC generates many climate
36
data products for smaller spatial and temporal scales for the user community.
These data products include daily gridded (1 o X 1o) rainfall (1951-2007) and
temperature data (1969-2005) over Indian region, district wise normal for various
surface parameters, grid point marine climate summaries for Indian Ocean region
etc.
(iv) Research and Development : Research projects on climate variability and
predictability studies for the Indian Region have been carried out. Major emphasis
has been given to monsoon which contributes 75-90% of the annual rainfall over
most parts of the country. Empirical models for the long range and extended range
prediction of the monsoon rainfall have been developed. Studies have also been
conducted on the links of regional climate variability with ENSO and global
circulation features and climate change issues over the Indian region. The centre
publishes the important research works as NCC research reports.
(v) Internet and Web services : NCC maintains internet facilities and a web site
(www.imdpune.gov.in) for all the four IMD offices of Pune. The web site provides
various information such as daily weather information, real time satellite pictures,
short range forecasts, agricultural advisories, farmers, details of surface
instruments, air pollution monitoring, cyclone tracks over Indian Ocean etc. Various
products from NCC such seasonal forecasts, 5-20 days OLR forecast, climate
diagnostic bulletins, research report etc. are being made available for the user
community through this web site.
Future Plans
In order to improve and broaden the scope of India specific climate services, the
following future activities are planned. It is also planed to extend the services to
entire south Asia.
37
(i) To upgrade activities of NCC to the level WMO recognized Regional Climate
Centre so that climate services can be provided to the entire south Asia.
(ii) Establishment of an operational dynamical prediction system for generating
global monthly and seasonal forecasts of rainfall and temperature at various lag
periods and to provide forecast outlooks for smaller spatial scales. Generation of
GCM model hind casts for at least last 20 years and preparation of verification
statistics of the as per the WMO guidelines.
(iii) To develop area specific seasonal forecast for both rainfall and temperature
based on statistical recalibration of GCM outputs. We may extend this service to
entire south Asia.
(iv) To prepare monthly and seasonal outlooks for the south Asian region based
on the ensemble model outputs from the centre and that from the WMO recognized
Global Producing Centres (GPCs). The climate outlook will be made available to
the users through the web site.
(v) To prepare high resolution daily grid point (0.5x0.5) rainfall data over Indian
region. These data can be used for recalibration of the model output as well as
verifying the skill of the dynamical models.
To take up projects on the regional climate variability and predictability, climate change and their impacts etc. It is planed to employ research assistants and research fellows to carry out research required for operational services in the project mode.

Hydromet Division 1 Background India Meteorological Department was made sole custodian of rainfall observations
in India vide Rainfall Resolution of 1890. In order to develop value added product
from the rainfall data achieved in IMD’ the Hydromet Division at New Delhi was
established in 1971. This Division is thus entrusted the responsibility of providing
necessary technical and operational support related to hydrometeorology to
various Central / State Govt. Organizations, policy makers, planner and the public
mainly dealing in the field of water resources development, water related disasters
like flood and drought, agriculture etc.
Hydrometeorological services benefit a wide range of user interests; viz.,
hydropower generation, flood control, agriculture, navigation, water resources
management, crop insurances environmental protection and public utility
requirements etc.
2 Functional Units Hydromet Division at HQ is rendering services through different Units namely (1) Rainfall Monitoring Unit (2) Design Storm Unit (3) Storm Analysis Unit (4) Glaciology Unit (5) Flood Met.

39
IMD has set up ten Flood Meteorological Offices (FMO) located over flood-prone
areas of the country. These FMOs are located at Ahamadabad, Hydrabad,
Bhubaneswar, Patna, Asansole, Jalpaiguri, Gauhati, Delhi, Agra and Lucknow.
FMOs provide necessary meteorological support to the Central Flood Forecasting
Divisions of Central Water Commission (CWC). During flood season, FMOs issue
Hydrometeorological bulletins to CFFDs for timely flood forecasting, which include;
- Quantitative Precipitation Forecast (QPF) in different ranges of rainfall for
the next 24 hours for the concerned catchments / sub-catchments.
FMOs keep round-the-clock watch during Flood Alert period as and when declared
by the Central Flood Forecasting Divisions of CWC. Hydromet Division provides
technical guidance and control to these field units.
3.2. Rainfall Monitoring
Hydromet Division is entrusted with the responsibility of, monitoring districtwise
rainfall on real time basis. At present, about 2300 raingauge stations of both IMD
as well as State Govt. agencies report weekly rainfall data on near real time basis
under the Districtwise Rainfall Monitoring Scheme (DRMS). Daily stationwise
rainfall data is collected, compiled, checked and processed at the Meteorological
Centers of IMD. The districtwise processed rainfall data is transmitted to the
Hydromet Division of IMD at New Delhi for preparation of periodical rainfall
statistics mainly district / met sub Divisional / country as whole, rainfall realized and
its departure from long term average for week and season. The output is available
both in tabular and pictorial form for the benefit of planners, policy makers,
agricultural scientists, civil and irrigation engineers, research scholars etc and is
also available on IMD ‘ s website.
40
3.3. Estimation of Design Storm for hydraulic structures
Hydromet Division provides Design storm values for designing major Hydraulic
structures like dams or reservoirs for irrigation or hydro-power generation as well
as for construction of railway and road bridges, drainage systems and designing
spillways. Design estimates, based on analysis of past rainstorms over the
catchment area are supplied to the design engineers for deciding Design Flood so
as to ensure safety of the structure.. A rainstorm capable of occurring over the
river basin is selected and subject to detailed isohyetal analysis to find out
estimates of Standard Project Storm (SPS) and Probable Maximum Precipitation
(PMP).
Division also provides rainfall values of various return period as an input for flood
estimates for construction of minor structures, like railway and road bridges,
drainage systems. For this purpose, India has been divided into 7 meteorologically
homogeneous zones and 26 sub-zones. The additional inputs provided are the
normal and heaviest rainfall observed at shorter duration, conversion factor for
short duration rainfall from 24 hr rainfall value, area reduction factor etc.
3.4. Glaciological Studies
Glaciers are important sources of renewable hydropower and water and sediment
transport into river system for development and utilization of water resources for
human sustenance. Himalayan glaciers are responsible for the perennial nature of
the rivers in the north India. Thus glaciological investigations are undertaken by
many agencies and Hydromet Division is participating in the expeditions and
extending meteorological support and recording observations for developing
climatology of the glacier. Thus by now the said services are provided to 21 glacier
expeditions
41
Division has established 31 snow gauges in Himalaya for an assessment of snow
cover and depth and thus snow melt potential. The proposal of extension of snow
gauge network in Sikkim area is under process.

Central Hydromet Observatory. Officers from the Division are delivering lectures on
Estimation of Design Storm to Post Graduate students of IIT Roorki.
43
4 Challenges and Proposed Extension / Modification of Existing Services
In course of time the demand from users has increased many folds. After
liberalization private agencies are approaching to undertake the studies on
payment basis with business interests.
As a result clients expect results with short notice, more cost effective and if
forecast then with more accuracy and higher lead time. Hence infrastructure
developed in past needs review with increasing demand. Hence Division has
planned program for Upgradation of Hydromet Services.
Division has identified 13 activity wise Technical challenges in meeting the
demands of users and developing objective methods in Hydrometeorology.
These challenges will be addressed by incorporating computer applications to have
more automation. It is proposed to procure modern computing system and
software to incorporate AWS , ARG and Radar data which will get installed under
Modernization Program of IMD.
44
Agro-Met Division Agrimet Division serves as a catalyst in enhancing agricultural production through
Agromet services and research. The service aspects include Agromet Advisories,
training, agromet observation and data management whereas the research
component include R&D on water requirements of crops, pest & disease, dry
farming research and crop weather relationship.
1. District Level Agromet Advisory Service
Integrated agro-meteorological advisory service is essentially a multi-institutional
programme with participating organizations like IMD, NCMRWF, Agricultural
Universities, ICAR Institutes, State Department of Agriculture, Department of
Information Technology, Department of Space, MS Swaminathan Research
Foundation, NGOs etc.
Considering the high variability of weather in time and space and need of farming
sector, IMD has upgraded the Agro-Meteorological Advisory Service from agro-
climatic zone scale to district level. From 1st June, 2008, IMD has started issuing
district level (612) districts) weather forecast for meteorological parameters up to 5
days in quantitative terms. These products are based on a Multi Model Ensemble
technique using forecast products available from number of models of India and
other countries. The products are disseminated through Regional Meteorological
Centres and Meteorological Centres of IMD located in different states after value
addition to these products and communicate to 130 Agromet Field Units (AMFUs).
Agromet Advisory with contingency planning is being issued/advised for problem
45
areas particularly with deficit/scanty/no rain through Integrated Agromet Advisory
Services.
In order to strengthen Information Dissemination Organization at
district/block/village level, District Agromet Advisory Service (DAAS) meeting were
organized in each of the state of the country inviting the officers/scientists from all
stakeholders with objectives to create appropriate information generation-cum-
dissemination mechanism as well as extension mechanism for communicating the
Agromet Advisory to the farmers.
2. Training
The training unit of this Div. has conducted (i) 6 weeks Agromet Core course, (ii)
Basic Agromet course and (iii) ‘On the Job’ training course recently.
Arrangement are being made for training course on ‘Agrometeorology towards
better advisories for serving end users requirement’ for AMFU Scientists/Technical
officers.
3. Data management
Agrometeorological data form the basis of any agricultural pursuit, whether
planning, development, operational or research. Agrometeorological parameters
recorded form a agricultural firm form database. These data are scrutinize,
archived and supplied to scientists, planners etc. Attempts are being made to clear
the backlog of Agromet Data.
46
4. Research and Development
Extensive R&D activities are also being carried out in the division so as to provide
better advisories to the farming community. Major thrusts areas of research directly
or indirectly contribute to the operational agrometeorology are:
Water requirements of crops
Forewarning of Pest & disease
Dry farming research
Crop weather relationship.
5. Water requirements of crops
Crop production can be maximized by better scheduling of irrigation. Scarce water
resources can be economically used by providing water to crops when it is known
to be most beneficial. For this purpose, precise water requirements of crops at
various growth stages are being studied through field experiments and regular
lysimeter measurements through 41 evapotranspiration measurement stations
located at different agro climatic zones in India.
6. Forewarning of Pest and diseases incidence
The possibility of occurrence of insects and diseases particularly under favourable
weather conditions when outbreak of pest and diseases occur is an important area
of study. In order to develop forewarning models of pests and diseases, the
following measures are being taken:
47
(i) Creation of data base through collection of historical data on outbreak of
insects and diseases and delineation of the regions prone to different insects and
diseases.
(ii) Utilization of pest / diseases- weather relationship already available at
different State Agricultural Universities (SAUs) / ICAR Institutes.
(iii) Identification of threshold values of weather parameters for each individual
phase of growth cycle of the pest / disease.
(iv) Development of prediction model and strategies for integrated pest
management based on weather parameters through about 20 collaborating
Agriculture Institution/Universities.
7. Dry farming research
Semi-arid regions constitute a major part of India comprising 9 states which
receives 400 to 1000 mm of rainfall. Scanty rainfall during crop growing season is
the major constraint for growing crop in the season. This need to be overcome by
adopting the risk management strategy through probability of rainfall occurrence
and water balance studies. Probability of wet and dry spells information in the
region also helps to plan not only sowing time but also adopt contingency planning
under weather vagaries. By analyzing long period rainfall data (more than 70
years) and computing moisture availability index for the stations in the semi-arid
region suitable cropping patterns are being suggested.
8. Crop weather relationship
Theoretical models of crop weather relationship enable to understand,
quantitatively, the role played by weather elements on crop growth and yield. Such
models have been applied to wheat, paddy, cotton and groundnut crops and
48
response of these crops in various phonological stages in relation to
meteorological factors have been studied. Fluctuations in weather with regard to
crop-factors like leaf area index, stomatal resistance, crop co-efficient, and dry
matter production are also been studied. Energy balance in the crop canopy for
cereals and legumes are being worked out.
49
SEISMOLOGY AND EREC DIVISION India Meteorological Department (IMD) is the nodal agency of Government of India
responsible for monitoring seismicity in and around the country. Timely
dissemination of earthquake information, to concerned state and central
government agencies, plays a very important role in dealing with the post-disaster
relief and rehabilitation related matters. Towards achieving these objectives, India
Meteorological Department (IMD) is maintaining a National Seismological Network
to keep a continuous watch on the seismic activity.
1. Earthquake Operational Centre
An Earthquake Operational Centre is functioning on a 24X7 basis at IMD
Headquarters in New Delhi. The responsibilities of the Centre include retrieval of
waveform data from remote field stations either in real time or through VSAT / dial
up communication facilities, data analyses and quick dissemination of earthquake
information to various user agencies including State and Central Government
departments dealing with relief and rehabilitation measures. The information
relating to under-sea earthquakes capable of generating tsunamis on the Indian
coastal regions is also disseminated to all concerned user agencies including the
Indian National Centre for Ocean Information Services (INCOIS), Hyderabad for
issue of tsunami related bulletins and warnings. The earthquake information is also
transmitted to public information channels, press, media etc. and posted on IMD’s
Website (www.imd.gov.in and www.imd.ernet.in). The Duty officer may be
contacted at the following numbers for earthquake related information:

ENVIRONMENT MONITORING &
RESEARCH CENTRE
BACKGROUND
IMD’s tradition of monitoring weather and climate spans more than 130 years
giving it a sound and useful dataset to fall back upon for environmental
assessment. The Ozone network was started as a globally pioneering effort as
early as in 1950 realizing that this trace gas plays a very important role in
atmospheric chemical mechanisms. It also started radiation measurements about
50 years back providing with an exclusive countrywide dataset for assessment of
solar energy resources.It established a network of 10 Background Pollution
Monitoring Network (BAPMoN) stations in the country in 1974 as part of a global
network. A well-equipped chemical laboratory was set up at Pune for conducting
rain chemistry studies and making atmospheric turbidity and air quality
measurements to quantify trends and acid rain threats.
Ongoing activities
Existing Environmental Monitoring Programme are as follows.
(a) Total Ozone : 6 stations
(b) Vertical Distribution of Ozone (Ozone sonde) : 4 stations
(c) Surface Ozone : 7stations
(d) BAPMoN : 10 stations
(g) Air Quality : 2 stations
(h) Skyradiometer : 1 station
(i) Environmental Impact Assessment (EIA)
Environment Meteorology Unit (EMU)
62
EMU provides specific services / inputs on meteorology and air quality for the last
25 years to the Ministry of Environment and Forests (MoE&F) in the assessment of
air pollution impacts likely to arise from Thermal Power Stations, Industries and
Mining activities in the country. Atmospheric diffusion models are employed for
carrying out air quality impacts of multiple sources located in different climate and
geographic conditions. More than 250 projects per months are being received for
evaluation. IMD serves on the Panel of Experts of various Committees of MoE&F
designated for grant of clearance.
The department maintains a meteorological observatory at Taj Mahal (Agra) to
monitor meteorological parameters at hourly intervals to study air pollution in Agra
region since 1976 under an agency scheme financed by MoE&F / Central
Pollution Control Board upto 1905 and by IMD afterwards. Periodical Reports
based on data of Taj Observatory, Agra have been prepared. ]
Air Quality, Precipitation chemistry and weather parameters are continuously
monitored at GAW Ranichauri (Uttrakhand)
National Ozone Centre
(a) Total ozone and Umkehr observation by Dobson Ozone
spectrophotometer are taken daily basis from 4 stations viz. Delhi, Varanasi, Pune
and Srinagar. At Delhi, Kodaikanal and Maitri (Antarctica) ozone is monitored with
Brewer Spectrophotometer, which has an additional facility to measure NO2, SO2
and UV-B radiation also.
(b) Vertical distribution of ozone is measured by balloon-borne ozonesonde
(IMD-made) fortinightly frequency at Delhi, Pune, Thiruvananthapuram and Maitri
(Antarctica).
(c) Surface ozone measurement is taken at 8 stations viz. New Delhi, Nagpur,
Pune, Kodaikanal, Srinagar, Thiruvananthpuram, Dakshin Gongotri and Maitri
(Anarctica).
63
Ozone data is available at the National Data Centre, Pune and also at the National
Ozone Centre at IMD, New Delhi. This centre has also been designated as the
Regional Centre for the Regional Association II (Asia) of the WMO Ozone has a
strong relationship with biomass burning, traditionally seen over eastern parts of
the subcontinent extending into that East Asia. This area is also a thickly vegetated
region releasing organic compounds that participate in atmospheric photochemistry
in whish ozone has a significant role to play. Thus the anthropogenic emission
define the residence times of various GHGs of biogenic origin via the ozone link in
this region. Monitoring of troposphereic ozone distribution over eastern parts of the
country, mainly in the NE region and Bay Islands, will be undertaken.
Air Pollution Section
Precipitation chemistry and Atmospheric turbidity - The ultimate fate of most
biogenic or anthropogenic gaseous emissions is their highest state of oxidation
which are acidic and render them water soluble too. Thus rain is a good indicator of
atmospheric composition. In recent years it has been noted that when certain
areas are subjected to high load of acidic deposition the natural alkaline buffer
action of soil derived crust gives way to acid rain , which is potentially harmful.
Intense monitoring of precipitation chemistry would be carried out in the Indian
BAPMoN, with newly added locations.
Activities Planned
(1) Green House Gas (GHG) and aerosol concentration variability needs to be
documented across the world to understand the global Carbon Cycle and compute
radiative forcing that may lead to global warming.
GHGs monitoring also be carried out to measure the ambient concentration of CO2,
CH4 and N2O at the surface from different regions of the country as an off-line grab
sampling strategy. In addition, 2 Baseline stations for conducting continuous
monitoring will also be opened during the period of XI FYP. The data will be
64
archived at a central location in the IMD New Delhi and will be analysed to quantify
source and sink potentials.
(2) A network of aerosol stations using sky radiometer for measuring the radiative
properties of aerosols will be established in the country .
(3) Aerosol Mass and Chemistry measurement in arid, coastal, island and high
altitude locations using High Volume Air Sampler and Black carbon measurement
using Aethalometer.
(4) Continue monitoring of O3 at Port Blair and Guwahati.
(5) Upgradation of surface ozone measurements at existing 6 stations and opening
of 4 more stations.
(6) To create a facility for archival of quality environmental data along with
metadata for parameters such as GHGs, O3, aerosols, radiation, air - quality gases
etc. for scientific research and applications and to create connectivity with NDC,
Website.
65
National Data Centre (NDC) i) Climatology System from MFI
Under the modernization of IMD, computing capabilities of National Data Centre
are being upgraded with the modern computing facilities relational data base
development system, improved data retrieval and a web based query system
through MFI (Meteo France International) NDC will be acquiring servers and
peripherals for data base development and also for web based queries.
The system at Pune is likely to be installed in the month of April, 2009.
ii) Climatological Data Rescue Scheme
India Meteorological Department (IMD) since its establishment in 1875, is
collecting meteorological data from large number of observatories, scattered all
over the country. Data recorded at field stations in the manuscript form are sent to
Meteorological Centers / Regional Meteorological Centers. These data, in the
manuscript form are preserved at Meteorological Centers (MCs) and Regional
Meteorological Centers (RMCs).
The scrutinized data are keyed and verified at these centers. After verification,
these data are sent to the NDC, Pune for archival. .
Monthly data since the inception of the observatories and daily surface data from
1969 onwards have been digitized and archived at NDC. Monthly means of
surface data prior 1969 are available in the archives. The daily surface data prior to
1969 is required to be put on electronic media. This has been taken under the
above mentioned plan scheme, where in, the data keying work is proposed to be
outsourced. It will be implemented at each RMCs and Pune, as major part of the
66
data are at these locations. It is planned that the data at MCs which are still in
manuscript form and not in any digital form will also be taken for data entry.
In summary, once the project is completed, NDC, Pune will have long series of
climatological data, which will definitely help the research community and
operational forecasters.
iii) Archival of Automatic Weather Station (AWS) Data in NDC
Background
It is well known that AWS data have more advantages over conventional manual
data recording as it is more consistent in their measurement, provides data at a
significantly greater frequency in all weather conditions all around the year. India
Meteorological Department is modernizing observational network all over the
country and 125 AWS stations have already been installed. The data transmitted
by AWS are received and stored in FM-14 Synop form at DDGM(SI) office,
Pashan, Pune. Also these synops are transmitted through GTS channel for
weather forecasting purpose. For archiving processed AWS data, a 2.4 GHz Radio
Link has been established in National Data Centre (NDC) for receiving AWS
synops. The processing, quality control and archival of AWS data in simple, user-
friendly format is very important to meet the growing demands of scientists and
other users in India and abroad.
AWS Data Archival
After transmission of AWS data on GTS, these synops need to be stored
permanently. Thus while deciding on AWS data storage in NDC, consideration has
been given to the ease of quality control and retrieval of the data. The use of
standard data format permits easy exchange of data and it further helps in
processing and quality control of data with a minimum of reformatting. For this
purpose, a flexible, simple and human-readable format was designed to archive
67
AWS data in NDC. This format has a provision to include quality control flag for
each data element in the 0-9 scale. Hourly observations sent by AWS stations are
archived in NDC after applying quality control procedures.
Plan scheme “Archival of AWS Data”
A plan scheme “Archival of AWS Data” has been approved by DGM for archiving
AWS data records in NDC. Supply order has been placed after receiving
expenditure approval (Rs. 9,85,949/-) from DGM office, New Delhi for procurement
of Hardware and Software under the scheme. The procurement of these hardware
and software will enhance the computing and data archival capabilities at NDC.
The GIS software under the scheme will be a useful tool in creating geo-spatial
maps of AWS data. The hardware and software will be installed and commissioned
by the end of Sept, 2009.
AWS data on Web:
AWS synops received from DDGM(SI), Pashan are first converted to data archival
format. Then these data records are further processed and quality control
procedures are applied. One day AWS data (previous day’s) are hosted on IMD
Pune website for public use.

Budget and Planning New initiatives (A) Approval, in principle, for initiating advance action to purchase additional
equipments under the modernization programme of IMD Phase-II and
Common Wealth Games-2010.
Under the modernization programme of IMD, which had been approved by the
Cabinet in Dec., 2007 at an estimated cost of Rs. 920 crores and to be
implemented in 2 years (Phase-I), orders for some of the major equipments have
already been placed. Processing of the cases for placement of orders for some
more items are also in an advanced stage and orders are likely to be placed
shortly. Already cash flow for one of the major components of the programme i.e.,
MFI project, has started. Some additional payments are also likely to materialize
during current financial year for the equipments which are on orders. An important
point to be noted is that actual cost of some of the items for which order is already
placed is considerably less than the cost projected earlier at the time of obtaining
Cabinet’s approval. As a result of this, phase-I of the modernization plan will be
implemented at a cost lower than Rs. 920 crores. Details of actual likely
expenditure during current financial year (2008-09) are being worked out and will
be presented to the Secretary, MoES during next meeting of the review committee
of MoES constituted under the Chairmanship of Secretary, MoES.
2. Considering that the 11th Plan allocation for IMD is quite large and there are
some long lead items which need to be procured, advance actions have to be
taken for planning and procurement of equipment in time so as to ensure full
utilization of funds during the current plan period. Already about 1½ years of the
current plan are over and only 3 ½ years are left to implement all other major
projects. Considering this, the Department has already started taking action for
preparation of papers for obtaining approval for Phase-2 of the modernization
76
programme. The main basis for planning the future observation systems is the
report of Dr. Sikka’s committee on observation system which has been accepted
by the Earth Commission. While the process of obtaining approval for Phase-2 is
in progress, it is considered necessary to start advance procurement actions for
purchase of equipments so that we are assured of incurring large expenditure,
particularly during next 2 Financial Years when the equipments for modernization
(phase-2) are expected to arrive. It is proposed to complete all the procurement
processes, except for placement of final order which will be done only after getting
project approval and allocation of funds. Similar approach was also adopted, after
approval from MoES, for procurement of equipments for modernization Phase-I.
Because of this strategy it was possible to place orders for major equipments
within about six months after getting approval from the Cabinet.
3. India is hosting the 19th Common Wealth Games during 3-14th October,
2010 in New Delhi. The Common Wealth Games is the biggest international event
in the recent past of the city of Delhi. The Weather Services are required to
support planning and coordination of Common Wealth Games activities. Nowcasts
are a particularly important component of the sports weather service requirement.
India Meteorological Department as a Govt. agency has to provide all weather
services for sport events. Forecasts will be required at 1-3 hourly interval on
temperature, humidity, wind and rain for each of the prime venues, and severe
weather warnings will be required at 10-15 minutes interval. To steer the task of
putting all equipments and systems in place, a Scientific Advisory Committee was
constituted by the Secretary, MoES and notified vide Office Order No. CWG-01
dated 1st May, 2007. The committee has recommended a network of 60 AWS, C-
Band Doppler Weather Radar, Low Level Wind Profilers-5 Nos., Lightening
Detection System-5 Nos. , Sun photometer-5 Nos. and Multiple Utility Vehicle-2
Nos. for this purpose. The entire system is likely to be in place before the end of
Financial Year 2009-2010 in order to provide adequate time for testing and fine
tuning before starting its actual operational use in October’ 2010.
77
4. For the phase-2 of modernization programme and to establish system for
venue specific forecast for Common Wealth Games-2010, it is proposed to initiate
advance procurement action in a similar manner for the specific equipments as
given in Annexure-I, which are long lead items and generally require lot of time for
installations and commissioning after placement of formal orders with the suppliers.
In view of the justification given above, MoES may kindly accord approval, in
principle for starting immediately procurement action for the equipments as per
Annexure-I enclosed at a total estimated cost of Rs.1169.85 Crore the major
portion of actual expenditure on the above equipments will be incurred during the
two Financial years 2009-2010 and 2010-2011.
(B) Case has been iniaited and is under process for obtaining approval from
MoES for construction of Radar buildings for installation of 12 Nos DWRs by
outside agency other than CPWD to avoid delay.
