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 optical imagers on the Himawari/MTSAT/GMS series.

Himawari-8, -9 and MTSAT-1R, -2

Calibration Event Logging

Himawari Calibration Portal provides information on instrument specification, calibration events and data outages of the JMA's geostationary satellites.

Infrared Inter-calibration with High-spectral-resolution Sounders

Within the GSICS framework, Himawari-8, -9/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 inter-calibration guide link below. Regarding the maturity level of GSICS Products, please refer to GSICS Product Catalog.

Visible and Near-Infrared Vicarious Calibration

Himawari-8, -9/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.
