Current and prospective GSICS Products ProductStatusComments GEO-LEO-IRINSAT-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) W_IN-ISRO-Ahmedabad,SATCAL+NRTC+GEOLEOIR,INSAT3D+IMAGER-MetopA+IASI_C_DEMS_ _demo_01.nc 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 GSICS-EP-16, Boulder, May 2015

GSICS-EP-16, Boulder, May 2015 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
