- GSICS (link is external)(GLOBAL SPACE-BASED INTER-CALIBRATION SYSTEM) is an international collaborative effort initiated in 2005 by World Meteorological Organization (WMO (link is external)) and the Coordination Group for Meteorological Satellites (CGMS (link is external)).
- The objective of GSICS (link is external)is to provide calibration corrections needed for accurately integrating data from multiple observing systems and ensuring consistent observations for climate monitoring weather forecasting, and environmental applications.
- ISRO (link is external)as a member organization of GSICS (link is external)is carrying out the inter-calibration activity for Indian meteorological satellites in order to provide the calibration correction coefficients to the international users.
