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 central homepage operated by NOAA/NESDIS in the U.S. for more details. The MSC contributes to GSICS as a GSICS Processing and Research Center (GPRC) for the MTSAT/GMS series.

GSICS for MTSAT

MTSAT Infrared Intercalibration 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 intercalibration methods and results, please see the "GSICS MTSAT Infrared Intercalibration Guide Web page.

MTSAT Infrared Intercalibration with AVHRR

MTSAT infrared images are compared with those observed by AVHRR on the U.S. NOAA polar-orbiting satellites in addition to GSICS infrared intercalibration. The two examinations made are a Clear Sky and Ocean comparison and a Smooth Cloud Top comparison. For details of the method of comparison for the two satellite images and how to read monitoring charts, please see the "MTSAT/AVHRR Intercalibration Guide Web page.
