Abstract

Since 1978, the Microwave Sounding Unit (MSU) onboard the NOAA american satellites provides the meteorological community with an enhanced temperature profiling capability. In addition to the 60GHz oxygen band observations, the future generation of these polar orbiting satellites will also include a humidity sounder up to 190GHz : AMSU-B.

To help understanding the radiative transfer in the atmosphere at these high millimeter wave frequencies, the UK Meteorological Office and the Laboratoire de Météorologie Dynamique (France) have jointly developed a microwave receiver at 89 and 157 GHz, frequencies corresponding to the AMSU-B window channels. The sounder has been flown in two international experiments in 1990. In this paper, we will focus on the gaseous absorption problem.
