Abstract

Seasonal snow cover in primarily non‐mountainous areas of South America was examined in this study using passive microwave satellite data from the Special Sensor Microwave Imagers (SSM/I) on board Defense Meteorological Satellite Program (DMSP) satellites. For the period 1992–1998, both snow‐cover extent and snow depth (snow mass) were investigated during the winter months (May‐August) in Argentina and Chile. Most of the seasonal snow in South America is in the Patagonia region of Argentina. Since winter temperatures in this region are often above freezing, the coldest winter month was the one with both the most extensive snow cover and greatest snow depth.
