GSICS-INTRODUCTION
The Global Space-based Inter-Calibration System(GSICS) is initiated in 2005 by WMO and the Coordination Group for Meteorological Satellites (CGMS). The purpose of the GSICS is to provide well-calibrated measurements of space-based observations for weather forecasting and climate monitoring. NMSC conducts calibration and research to produce accurate measurements of GK2A AMI(Advanced Meteorological Imager) as GSICS Processing and Research Center(GPRC).
Activities of NMSC for GSICS
NMSC has conducted inter-calibration for calibrating MI infrared channels which is based on the GSICS (Global Space-based Inter-Calibration System) Coordinate Center (GCC) Algorithm Theoretical Basis Document (ATBD). The hyperspectral Infrared Atmospheric Sounding Interferometer (IASI) and Cross-track Infrared Sounder (CrIS) on the low Earth orbit satellite are used as reference instrument.
For visible channels calibration, NMSC performs the vicarious calibration method by using earth target(ocean, desert, WC(Water Cloud) and DCC(Deep Convective Cloud)) and GEO-LEO inter-calibration methods ray-matching and GSICS DCC.
