Information about snow depth

Main menu

 

The snow depth map is published at around 7 am CET from 1 November until 30 June. 

The map is based on calculations from the operational snow hydrological service of the SLF (OSHD), using input data from the operational weather forecast models of MeteoSwiss. The calculations take into account various processes such as the settlement of the snowpack by its own weight, melting in the event of significant warming or when rain falls into the snowpack. Also taken into account is when the snow falls on snow-free and still warm ground and therefore melts again.

The snow depth is displayed for all altitudes.  The data are presented with a resolution of approx. 250x250 m. 

A time chart for values of the individual measurement stations can be accessed from the measured data map.
