An automated system has been developed for monitoring snow cover over South America. The system uses observations in the visible, middle infrared and infrared spectral bands from the Imager instrument onboard Geostationary Operational Environmental Satellite (GOES). Maps of snow cover are generated on a daily basis at a spatial resolution of 4 km. In the Letter, we present the results of snow cover monitoring during an 18-month period extending from May 2000 to November 2001. Seasonal changes of the snow-covered area are analysed. The extent of wintertime snow cover in South America was found to be lower than reported in earlier studies.
