ESTIMATION AND DISCUSSION OF LONG-TERM SNOW DEPTH BASED ON SSM/I SATELLITE DATA

Abstract

In the past, the snow algorithm for Microwave Scanning Radiometer - Earth Observing System (AMSR-E) was developed by Tsutsui, Koike et al (2005, 2007) . This algorithm was improved for Special Sensor Microwave Imager (SSM/I) in this paper. It is for investigating long-term snow depth before Aqua is launched (2002) . Furthermore, snow depth in the Northern Hemisphere of the period from 1988 to 1999 was estimated from SSM/I satellite data by this algorithm, and the estimation result was argued.
