ERS-1 Instruments

The main objective of the microwave radiometer (MWR) on ERS-1 was the measurement of the integrated atmospheric water vapour column and cloud liquid water content, as correction terms for the radar altimeter signal. In addition, MWR measurement data were useful for the determination of surface emissivity and soil moisture over land, for surface energy budget investigations to support atmospheric studies, and for ice characterisation. The ERS-1 mission ended on 10 March 2000 and MWR measurements were continued on board the ERS-2 satellite.
