Paper Abstract

Global Space-based Inter-Calibration System (GSICS) is a critical space component of Global Earth Observation System of Systems (GEOSS) that provided users with high-quality inter-calibrated satellite measurements. As part of the GSICS, imaging instruments on geostationary (GEO) satellites have been inter-calibrated with hyperspectral instrument Atmospheric Infrared Sounder (AIRS) and Infrared Atmospheric Sounding Interferometer (IASI) on Low Earth Orbit (LEO) satellites. This paper reports the GSICS GEO-LEO inter-calibration at NOAA/NESDIS, for GOES-11/12 with AIRS (since January 2007) and IASI (since June 2007), and of METEOSAT-7/8/9, MTSAT-1R, and FY-2C with AIRS and IASI since August 2008. Major components of the operation are reviewed, including algorithm development, data processing, product generation, results dissemination, and selected inter-calibration examples. The preliminary results of the GSICS correction show that the fully functioning GSICS is a powerful tool to monitor instrument performance, to correct sensor bias, and to diagnose the root cause of calibration anomalies.
