Global Space-based Inter-calibration System (GSICS)

GSICS is one of the space components of the World Meteorological Organization (WMO). Its mission is to provide users with high-quality and inter-calibrated measurements from operational satellites. Please see the GSICS portal operated by WMO for more details. The MSC contributes to GSICS in its role as a GSICS Processing and Research Center (GPRC) for the MTSAT/GMS series.

GSICS for MTSAT

MTSAT Infrared Inter-calibration with High-spectral-resolution Sounders

Within the GSICS framework, MTSAT infrared data are operationally compared with those from high-spectral-resolution sounders, such as the AIRS equipment on the AQUA satellite and the IASI instrumentation on the Metop satellite. For details of inter-calibration methods and results, please see the GSICS MTSAT infrared inter-calibration guide web page.
MTSAT-2 infrared inter-calibration was started on 11 May, 2010. Its inter-calibration system was constructed based on the MTSAT-1R system, but was updated to follow the latest GSICS conventions.

MTSAT visible vicarious calibration

MTSAT visible data are operationally monitored based on comparison of observations with radiative transfer calculation. For details of vicarious calibration methods, please see the MTSAT Visible Vicarious Calibration Guide web page.
