AbstractA system based on satellite remote sensing has been developed for snow cover monitoring of a number of basins in the Spanish Pyrenees. The snow covered area is used as an input for snowmelt runoff forecasts on 42 basins using the Snowmelt Runoff Model (SRM). The forecasted snowmelt volume accumulated from May to September is sent to the hydropower companies for water resources management. A subpixel analysis is carried out to map the snow cover with Advanced Very High Resolution Radiometer (AVHRR) data on board the National Oceanic and Atmospheric Administration (NOAA) satellites. Two mapping methods are compared: a linear combination of a visible and a near infrared channel, and a snow classification based on the Normalized Difference Snow Index (NDSI) and the Normalized Difference Vegetation Index (NDVI).
