Information about the new snow 1-day map

Main menu


During wintertime this map is published daily at 9.30 am. It shows the amount of fresh snow that has fallen in the preceding 24-hour period. It is measured by the SLF observers in flat terrain which is protected from the wind, in most cases between 7 and 7.30 am (information on measuring). The variables are measured by hand, so that the recorded values are fairly reliable. They are not always verified, however, so errors cannot be ruled out.

Most of the measuring sites are situated in intermediate altitude zones, between 1000 and 2000 m. If the fresh snow at the site is moist, or if rain is falling, the amounts of snow lying at higher altitudes will be greater. In such cases, a more accurate picture is provided by the map with measured data at stations. This map also shows the automatic IMIS measuring stations at higher altitudes. With ; a specific altitude zone can be selected with the hamburger button (≡) at the top right.
