The Global Space-based Inter-Calibration System (GSICS) is an international collaborative effort initiated in 2005 by WMO and CGMS to monitor, improve and harmonize the quality of observations from operational weather and environmental satellites of the Global Observing System (GOS). GSICS aims at ensuring consistent accuracy among space-based observations worldwide for climate monitoring, weather forecasting, and environmental applications. This is achieved through a comprehensive calibration strategy which involves:

  • monitoring instrument performances,
  • operational inter-calibration of satellite instruments,
  • tying the measurements to absolute references and standards, and
  • recalibration of archived data.

GSICS delivers calibration corrections needed for accurately integrating data from multiple observing systems into products, applications and services.

GSICS contributes to the integration of satellite data within the WMO Integrated Global Observing Systems (WIGOS) and within the Global Earth Observation System of Systems (GEOSS) of the Group on Earth Observations (GEO).

In accordance to the GSICS Implementation Plan GSICS relies on a GSICS Coordination Centre (GCC), several GSICS Processing and Research Centres (GPRC) operated by each satellite operator, and Calibration Support Segments (CSS) such as field sites and laboratories. Activities are overseen by a GSICS Executive Panel assisted by a Research Working Group (GRWG) and a Data Management Working Group (GDWG).

The GRWG and GDWG advise the Executive Panel and assist in the planning and implementation of GSICS research and data management activities respectively. The GRWG consists of scientists, and the GDWG of data management experts, representing the participating agencies.
