There is a long tradition of snow science at Filefjell. In 1967 our first automatic snowpillow was established at Filefjell, and the site was central during the hydrological decade (1960-1970). Since the autumn 2009 we have established a new snow research station at Filefjell.
The snow research station at Filefjell was established to study the following objectives:
In addition, we want to measure the small-scale variability in SWE and to use it for validation of different snow models.
The research station is located at Filefjell at 953 m a.s.l., Oppland County, nearby E16 between Tyin and Borlaug along the road from Oslo – Bergen. It is located at the main water- and weather divide between the western and the eastern part of Norway. The station is located close to the NVE cottage "Varden" and the station is easy to reach from both our head office in Oslo and from our regional office in Førde. In winter, the station is frequently visited by our field hydrologists. Every year there are on average 300-400 mm of snow (in SWE) at the snow station, and the snow season lasts normally from late October to June.
Snow depth and SWE are measured using different measuring techniques. Both snow pillows (different shapes and sizes) and snow weights (different sizes) are used for measuring SWE, while snow depth is measured by ultrasound and gamma sensors. In addition, manual measurements of snow depth and snow density are done on a regular basis during the snow season. Also snow and soil temperature are measured at different depths. Ground water level is also measured at the site. The Norwegian Meteorological Institute (met.no) has also established an automatic weather station at the site. This station measures precipitation, temperature, humidity, wind speed and also snow depth (ultrasonic).
There is a long tradition of measuring snow at Filefjell. During the international hydrological decade (1965-1974) Filefjell was chosen as one out of three representative areas in Norway. In the period 1967-1974 there was an extensive field measurement program for validation of estimates of water balance. In autumn 2009 the station at Filefjell was extensively upgraded - from simply measuring the water equivalent (SWE) using one snow pillow, until today having a total of 99 automatically measured parameters.
Data from NVE is public. Please contact us if you need further information or want to analyze data from the site.
