Davos Laret (LAR) Primary CryoNet Station Information
This station has recently been built up in relation to two ESA-based projects. The intention is to develop a well equipped reference site to facilitate satellite ground truth cal/val activities in mountainous environment but also as a reference station for snow cover studies ranging from snow microstructure to snow climatology. The location of the station North of the Wolfgang pass, open to the south but slightly sheltered by a forest to the North makes it an ideal site for snow cover measurements with little influence by the wind. There are also snow depth records available from the nearby Davos Laret station and quite a few studies on snow-forest interactions have been conducted in the surroundings of the site.
