| Overview |
|
The wet snow cover product provides binary information on melting snow for non-forested areas. The product is generated for the European Alps. Water bodies, forested areas, as well as areas affected by radar shadow or fore-shortening are masked. Bare ground and dry snow are identified as one class.
Products are provided including metadata meeting INSPIRE standards.
