The University of Oulu studies the melting of snow and the migration of meltwater into nature


In the surroundings of the measuring booth located at the University of Oulu’s Oulanga research station, about one hundred meters of fiber optic cable as strong as a clothesline are being tested, which very precisely measures the temperature every meter. After this winter’s testing, the intention is to install up to a couple of kilometers of measuring cables in the terrain for the actual research during the next winter.

According to the University’s Snow Hydrology and Modeling research group, the snow measurement network already in use in Finland and the new measurement technology will provide new information about the importance of snow for northern water resources.

The amount of snow, rapid periods of snow melting and changes in frost conditions affect, among other things, water reserves and the water cycle.
