At 16:47 on 4 Nov. 2004 (JST), a data deficit (all data was 0 level) in one of the observation channels of JAXA's Advanced Microwave Scanning Radiometer for EOS (AMSR-E) was found. AMSR-E is mounted on the National Aeronautics and Space Administration's (NASA's) earth observation satellite "Aqua." After the analysis of this phenomenon, it was ascertained that receiver A for one of 6 observation frequency bands (89GHz), operated with receiver B in parallel to assure observation field of view, has been defective to output observation data after15:02 (the same day).
