The Sub-Satellite Validation System for on-Orbit Calibration Monitoring of Russian Meteorological Satellite Instruments and Satellite Products Validation (CAL/VAL System)

This paper describes the Calibration/Validation (CAL/VAL) System for Russian Meteorological Satellites, developed between 2012 and 2016 by the Research Center “Planeta” (Roshydromet) in collaboration with research institutes of the Russian Academy of Sciences, Roshydromet, and Roscosmos State Corporation. The system is designed for monitoring of on-board calibration, external calibration (including inter-calibration with international satellite), and validation of data products. The CAL/VAL System for Russian Meteorological Satellites was developed to fulfill Roshydromet’s international commitments as a participant in the WMO and a member of the WMO Global Space-Based Inter-Calibration System (GSICS).
