Finnish Environment Institute snow course data from 2004 to 2024 and subset of longer time series

The data includes snow course data from Finland covering winters 2004/05 to 2023/24 and 14 quality checked longer timeseries starting from the 1940’s.

The data consist of snow water equivalent (swe), snow depth, and density observations. For the long snow courses, additional observations are made, including fraction of snow free-area, slope/topography, land use type, forest density, and ice on ground. For all snow course observations spatially representative mean values of swe and snow density are provided.
