DATA MANAGEMENT AND QUALITY CONTROL
16
BMKG
ICA&D : INDONESIA CLIMATE ASSESSMENTAND DATASET
• What is ICA&D ?– ICAD is sustainable system for collecting, archiving,
quality control, analysis and dissemination climate daily data
– Collecting data from observation stations– Archiving data in centralized database– Quality control : checking the quality of data and
homogeneity test– Dissemination strategy : publish data and graph via
website

BMKGMAIN OUTPUT OF THE DBMS
• Level #1 data:observed data from many parameters with many time-step (10 minutes, hourly, daily), many forms, and many instruments.
• Level #2 data: derived data into hourly, daily, weekly, ten-days, monthly for every parameter.
• Level #3 data:processed data i.e. average, normal, maximum, minimum, extreme, indices, etc.

TOPICS FOR YMC RESEARCH ACTIVITIES
Detection of monsoon onset and withdrawal
MJO – diurnal cycle interaction, its prediction and impact assessments
Mesoscale Convective System: better understanding of MCS characteristics at each phase & impact to wind and precipitation
Improving model prediction skill: data assimilation
Wave propagation
Aerosol and its impact to climate

ON-PROGRESS RESEARCH ACTIVITIES
Ina-PRIMA (Indonesian Program Initiative on Maritime Observation and Analysis)• BMKG – NOAA – P2O LIPI• Period : Feb 20 – Mar 16, 2017• Track : Jakarta – Indian Ocean – Sabang – Pidie – Malaka Strait – Jakarta
To maintain the Research Moored Array for African-Asian-Australian Monsoon Analysis and Prediction (RAMA) buoys
To observe the marine meteorology data (e.g. CTD), atmospheric, oceanography, and marine-geophysics observation data
23
BMKG
ON-PROGRESS RESEARCH ACTIVITIES
Year of Maritime Continent (YMC) 2017-2019 which will focus on sub-seasonal to seasonal (S2S)variation and its interaction with diurnal cycle
• Identification of Madden Julian Oscillation (MJO) signal and interaction with diurnal cycle at multielevation station in southern Papua
MJO phasew = weak
Permana et al (AGU, 2016)
24
BMKG
ON-PROGRESS RESEARCH ACTIVITIES
• On progress: MJO signal identification from Weather Radar and radiosonde data to better understandthe mechanism of MJO cycle over Maritime Continent
25
BMKG
MODELING RESEARCH ACTIVITIESWRF COSMO
• Run daily with initial condition : 12:00 UTC
• 2017-2018 focus on data assimilation including conventional observations (e.g.AWS, radiosonde) and radar data
