Participation in EP, GDWG, GRWG
• Points of contacts/meeting participants:– EP: Mr A S Kiran Kumar ([email protected])– GDWG: Dr Pradeep Thapliyal ([email protected])– GRWG: Dr Pradeep Thapliyal ([email protected])
• Main contribution to GDWG actions– GSICS Website development (internal assessment)
• Main contribution to GRWG actions– Intercalibration procedure established for INSAT-3D Imager and Sounder– Sample products along with GPAF submitted to the GCC for evaluation, initial review
report received and product is being modified for resubmission. – Diurnal variation in intercalibration using AIRS and IASI data.
• Comments, feedback– Participated in GRWG and GDWG meeting held in New Delhi during 16-20 Mar 2015.

GEO-LEO-IR INSAT-3D / IASI intercalibration.Sample Demo Products submitted for review by GCC
IASI-L1C data through Eumetcast has data gaps. Standing order setup with EUMETSAT
• Issues with the naming convention CCCC code (DEMS for IMD New Delhi)

• IASI L1C Data through Eumetcast – large data gaps leading to insufficient matchup points for NRTC products.
• Following discussions at GRWG/GDWG meeting in Delhi an arrangement has been made with EUMETSAT for IASI-L1C data over INSAT region through THREDDS server

Summary of ISRO GSICS Products GSICS recommended procedure adopted for INSAT-3D Imager/Sounder product.
Presently only IR channels attempted
VIS channels initiated using lunar calibration method.
MODIS DCC database will be very helpful in implementing VIS/SWIR calibration.
Same procedure will be adopted for Kalpana and INSAT-3A.
Switching from EUMETCAST data reception to Standing order through Eumetsat GSICS THREDDS server.
Archived data in the same format required to processing the past data
Training: Short term for a Data Working Group scientist and long term for a Research Working Group scientist will greatly help in making GSICS products operational
