Abstract

In 1987 and 1990, NASDA of Japan launched Marine Observation Satellite-1 (MOS-1) and MOS-1b. On these satellites, the Microwave Scanning Radiometer (MSR) is installed, and until 1996, it had been observing the snowpack in Hokkaido, Japan during the snow season. MSR is a passive sensor that receives weak microwave noises at two frequencies (23.8 and 31.4 GHz) radiated from the surface of the ground. MSR is not able to obtain the local snowpack characteristics but can provide macroscopic snowpack information over a wide area. This paper analyzes the statistical relationship between the depth/grain size of the snowpack in the Hokkaido region and the brightness temperature/emissivity observed by MSR on MOS-1
