Snow Data Assimilation System (SNODAS) is a modeling and data assimilation system developed to provide estimates of snow cover and associated parameters to support hydrologic modeling and analysis (Barrett 2003). SNOWDAS integrates multiple data sources including satellite and ground based data into a snow model to produce snow depth and snow water equivalent data.
Snow Depth: Depth of snow
Snow Water Equivalent (SWE): Depth of water if snow were to melt completely (volume/area)
