Update on in-flight performance of the Japanese Advanced Meteorological Imager

The Japanese Advanced Meteorological Imager (JAMI) was developed by Raytheon and delivered to Space Systems/Loral as the Imager Subsystem for Japan's MTSAT-1R satellite. MTSAT-1R became formally operational on 2005 June 28. This paper reports the first 2-km infrared synoptic imagery ever collected from geosynchronous orbit and provides an update on in-flight performance of JAMI. The performance areas discussed include radiometric sensitivity versus spectral channel, calibration accuracy versus spectral channel derived from comparisons of JAMI and AIRS measurements and scattered light performance around local midnight.
