Current position: Home > GSICS Calibration Monitoring
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 Himawari/MTSAT/GMS series.
Himawari Calibration Portal provides information on instrument specification, calibration events and data outages of the JMA's geostationary satellites.
Within the GSICS framework, Himawari-8/AHI infrared data are routinely compared with those from high-spectral-resolution sounders, such as the AIRS equipment on the Aqua satellite and the IASI instrument on the Metop satellite. For details of inter-calibration methods and results, please refer to the infrared inter-calibration guides links bellow. Regarding the maturity level of GSICS Products, please see GSICS Product Catalog.
Himawari-8/AHI visible and near-infrared data are routinely monitored based on comparison of observations with radiative transfer calculation. For details of vicarious calibration methods, please see the following vicarious calibration guide web page.
