RA-VI 16, Helsinki, 11-17 Sept 2013 2
Application areas for meteorological data acquisition Data as the basis of meteorological products and data for the
following application areas
numerical weather forecasts
weather surveillance and warnings of severe weather phenomena
surveillance of atmosphere and climate
meteorological applications (aviation, ocean shipping, media etc.)
climatological applications (consultancy, hydrology etc.)
meteorological and environmental research
Key Area: WIR, user requirements, application areas
RA-VI 16, Helsinki, 11-17 Sept 2013 5
Stations operated by Deutscher Wetterdienst 4 Regional Oberserving Network Groups
Hamburg, Potsdam, Offenbach, Munich
65 Stations with professional observers, 35 occupied 00-24 UTC, 30 only daytime48 measuring radioactivity (air+precipitation)
28 RBSN Stations 11 Climate Reference (traditional equipment)
4 GSN-Stations (GCOS) 1 GUAN Station 1 GAW Station
114 Automated Weather Stations
17 Weather Radar Stations
9 Aerological Stations
4 Wind Profilers
+34 Stat. as part of Bundeswehr Geoinfo Service
Key Area: Design, planning and optimized evolution
RA-VI 16, Helsinki, 11-17 Sept 2013 6
Additional Stations operated by DWD and Partners
1781 Voluntary Stations (climate; wind; precip), 1365 reporting online (24/1 reports per day)
Ship-based:
740 Voluntary Observing Ships (VOS)
19 Ship AWS (24 reports/day)
Last but not least …:
1292 Phenological stations (observing plants)
1500 Partner stations (approx) (motorways, fed.states, wind-energy, (nuclear) power-plants, universities, military)
Key Area: Design, planning and optimized evolution

Monitoring and Quality Control
Key Area: Integrated observing system operation
RA-VI 16, Helsinki, 11-17 Sept 2013 8
Tools and views for technical Monitoring
Number of station requests per minute
Number of SYNOPs produced per minute
Key Area: Integrated observing system operation

Quality control quality control of data
step 1: automated quality control at station (realtime)
step 2: automated quality control at central database (realtime);semi-automated quality control in central office (near
realtime) (software tool „QualiMET“ - central version)
Monitoring 24/7 since 2012/01
step 3: semi-automated quality control at DWD‘s regional network groups (software tool „QualiMET“; data processing after
max. 10 days)
step 4: semi-automated quality control of the values at theclimatological observation times in central office(data processing within 2 years)
each dataset will be flagged with a quality level
each value will be flagged with different quality information

Climatological reference stations
To avoid wrong interpretation which is caused in the automatic measurements
Conventional measurements for 10 years 3 measurement per day: 06:30, 13:30 and
20:30 UTC 11 stations are selected, each is
representative for a special area of Germany
To improve methods for homogenization of climate time series and data generation Brocken: Brocken:

Results
WIGOS is part of the current DWD strategy 2014 - 2020
Implementation of the ten WIGOS key areas is mainly realized in DWD
DWD will be the national integrator for meteorological observations and meta data
Standardization of observations is realized in all meteorological networks of DWD (baseline network, secondary (= voluntary) network)
European standardization in marine network started in last year
Integration of additional partnership networks is planned
