Filefjell/Kyrkjestølane
Reference CryoNet Station Information

It is a long tradition of snow research at Filefjell/Kyrkjestølane - already in 1967 the first snow pillow was established. During the international hydrological decade (1965-1974), Filefjell/Kyrkjestølane was selected as one of three representative sites in Norway. In the period 1967-1974 there was an extensive measurement program at the research site for validation of water balance modells (Furemyr and Tollan, 1975).

The area around the station is characterized by low shrub vegetation, heather and bog. A side stream of the river Sula drains westward. The area close to the station is relatively flat, but on both sides of the valley it is mountains at 1300-1500 masl.

The dominant wind direction is mainly from west or east, as the mainvalley runs east-west. Most of the snow comes with westerly winds. The winter season usually beginn in late October and ends in the middle of May and it is on average 320 mm of snow (SWE) at snow maximum (measured with a standard snow pillow (NVE1997) in the period 1967-2007).

* The Automatic snow measurements began in 1967, while precipitation and wind are measured continously since 1998, ground water level is recorded automatically since 2003, while automatic measurements of snow depth, air humitity, air temperature, radiation and snow temperature began in 2009.
