Data Deficit of Advanced Microwave Scanning Radiometer forEOS (AMSR-E)

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).

With this situation in mind, JAXA will conduct a investigation to
determine the cause and advance measures for its recovery including
switching on to the redundant system under the cooperation with NASA.

The condition of the satellite and other receivers for other frequency
bands are normal.

(annotation 1)
Aqua was launched on 4 May 2002, and is in normal observation
operation.

(annotation 2)
The AMSR-E is a microwave radiometer intended for performing
observations of sea surface temperature, precipitation and rainfall.
The AMSR-E performs the observations over six frequency bands
: 6GHz ,10 GHz, 18 GHz, 23 GHz, 36 GHz, 89 GHz.
