Paper Abstract

The U.K. Meteorological Office is procuring the humidity sounding element of the Advanced Microwave Sounding Unit (i.e. AMSU-B). This consists of a five channel microwave radiometer with channels centered at 89, 150, 183+/- 1, 183+/- 3, & 183+/- 7 GHz with a field of view of nominally 1.1 degree(s) (i.e. 15 km footprint at nadir). To characterize the radiometric behavior of AMSU-B an extensive series of tests have been performed on the engineering model in a thermal-vacuum chamber where the instrument can view an earth target and space target. Results showing the sensitivity, absolute calibration accuracy and linearity of the five channels are presented and show the instrument is within specification.
