Microwave Scanning Radiometer (MSR)

NSSDCA ID: 1990-013A-03

Mission Name: MOS-1B
Principal Investigator:

Description

The Microwave Scanning Radiometer (MSR) was a passive microwave radiometer with two frequency channels designed to provide information on snow cover and sea-ice extent, atmospheric liquid water and water vapor content, ocean wind speed and large-scale sea surface temperature. The instrument is a Dicke-type radiometer using a mechanical conical scan with the offset parabolic reflector rotating at 18 rpm. The instrument used two different integration times for both channels: 10 and 47 microsecond. The two channels were: Channel 1 at 23.8 GHz H polarization with a ground resolution of 32 km with a swath width of 317 km and Channel 2 at 31.4 GHz V polarization with a ground resolution of 23 km and swath width of 317 km. Both channels provided 1.5 degree K radiometric resolution and a dynamic range of 30 - 330 degrees K at a data rate of 2 kbps.
