Abstract
The Global Space-based Inter-Calibration System (GSICS) is a critical space component of the Global Earth Observation System of Systems (GEOSS) that provides users with high-quality inter-calibrated satellite radiances. In an early development, GSICS has implemented the inter-calibration of imaging instruments on geostationary (GEO) satellites with hyperspectral sounding instruments AIRS and IASI on Low Earth Orbit (LEO) satellites. This paper summarizes the major components and the theoretical basis of the baseline algorithm that is common to all implementations, and demonstrates the initial impact of the GSICS Correction.
