Global Space-Based Inter-Calibration System annual meeting

Darmstadt, Germany, 11-15 March 2024

This event on space-based inter-calibrations will discuss inter-calibration algorithm developments and results as well as pertinent calibration-related topics.


The Global Space-Based Inter-Calibration System group monitors, improves and harmonises the quality of observations from operational weather and environmental satellites. This event is organised and hosted by EUMETSAT at its premises in Darmstadt, Germany.

The Global Space-based Inter-Calibration System (GSICS) is an international collaborative effort set up in 2005 by the World Meteorological Organization (WMO) and the Coordination Group for Meteorological Satellites (CGMS). Its goal is to monitor, improve and harmonise the quality of observations from operational weather and environmental satellites in the global observing system (GOS). EUMETSAT has been is a member of GSICS since its foundation and currently chairs the Executive Panel and Research Working Group. EUMETSAT will also host this meeting at its headquarters in Darmstadt, Germany.

The GSICS group strives to ensure 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 performance,
  • the operational inter-calibration of satellite instruments,
  • tying the measurements to absolute references and standards, and
  • recalibrating archived data.

The group delivers the 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) as part of the Group on Earth Observations (GEO).

The GSICS meeting serves as a platform for coordinating efforts on inter-calibration algorithm developments as well as for exploring other pertinent calibration-related topics. The use of GSICS techniques in support of MTG-I1 commissioning will be showcased during the meeting.
