This app shows the current snow cover area in comparison with a 30-year climatology that was generated from a climate reanalysis. The current snow cover is obtained from Nasa’s Terra/MODIS satellite observations. The app is automatically updated when new observations are available. You can select the entire Alps or a river basin subregion. The plots will appear after a few seconds load time.
The method is described in the following publication:
