The project aims at creating a global database of snow parameters for climate research purposes. In addition to a historical data set comprising of 15 to 30 years of snow data an operational near-real time snow information service will be demonstrated. Information on two essential snow parameters: snow water equivalent (SWE) and areal snow extent (SE) will be provided. The database and the demonstrated snow service will be based on data acquired from active and passive, optical and microwave-based spaceborne sensors combined with ground-based weather station observations.
