Advanced Microwave Sounding Unit - B
|Within Vocab||SeaVoX Device Catalogue|
|Definition||A five-channel microwave radiometer designed for humidity and precipitation sounding in nearly all weather conditions. AMSU-B is a cross-track, line scanned instrument which samples ninety consecutive scene radiances in a continuous fashion, and measures atmospheric humidity profiles by examining five bands of microwave radiation ranging between (89.0 - 193.31)GHz. The instrument consists of a scanning parabolic reflector antenna which rotates and focuses incoming radiation from the atmosphere into a quasi-optic system. The frequencies of interest are then separated into three discreet feed horns of the receiver assembly. AMSU-B works in conjunction with AMSU-A to provide a twenty-channel microwave radiometer. The swath is 2250 km wide, and the spatial resolution is 16 km (horizontal) at nadir. The scan period is 8/3 seconds. The instrument covers +/- 49.5 degrees cross-track from the sub-satellite point, and the instantaneous field of view is 1.1 degrees circular. AMSU-B central frequencies are: (89.0, 150.0, 183.31 +/- 7.0, 183.31 +/- 3.0, 183.31 +/- 1.0) GHz. Flown on NOAA-15, NOAA-16, NOAA-17. http://www.wmo-sat.info/oscar/instruments/view/33|
