Paper Abstract

Fengyun-3C (FY3C) launched on 23 Sep, 2013 and InfraRed Atmospheric Sounder (IRAS) start to work on 30 Sep. Verification of instrument performance is an essential step before the L1 data distributed operationally. Verification performance including: BlackBody temperature, channel noises, radiance data assessment, Geo-location evaluation, instrument parameters trending, et al. Noise Equivalent Differential Radiance (NEdN) of all IR channels meet specification and got improvement on FY3B. IRAS L1 data are evaluated with Infrared Atmospheric Sounding Interferometer (IASI) measurements onboard European MetOp-A satellite using cross comparison method, biases are within 1K for all IR channels except ch1 and ch9. Trends of instruments components temperature are also discussed.
