Due to the heating caused by black carbon, the spring-time average increase in discharge was up to 20 % when compared to pure snow cases.
In cooperation with University of Oslo, the energy company Statkraft owned by the Norwegian state and the Finnish Meteorological Institute researchers did a modelling study how much black carbon influences snow melt in Norway at the lake Atnsjøen catchment area.
