Abstract

During the winter of 1994, a three frequency polarimetric radar system operating at 35, 95, and 225 GHz was configured to take simultaneous measurements of the Mueller matrix and normalized radar cross section (NRCS). In addition to the radar measurements, in situ data characterized the snow pack and meteorological parameters. It was found that NRCS is inversely related to the amount of liquid water content in the snow pack up to the depth of penetration. Additionally, a supervised classification using the minimum distance classifier was used to classify the data into four snow type categories with a 97% accuracy
