This dataset contains datasets of sub-canopy meteorological variables acquired in coniferous forest stands in Switzerland (Davos, Engadine) and Finland (Sodankylä) during the winters 2018 and 2019. The data are presented and used in the publication: Mazzotti, G., Essery, R., Webster, C., Malle, J., & Jonas T. (2020) Process-level evaluation of a high-resolution forest snow model using observations from mobile multi-sensor platforms Water Resources Research, under review

The above publication must be cited when using this dataset, and the user is referred to the publication for additional detail.

Data are grouped into 4 folders: 1) Point data includes wind speed data measured with stationary meteorological stations 2) Transect data includes data of incoming short- and longwave radiation, air and snow surface temperature acquired with an automated calblecar system along within-stand transects 3) Grid data includes data of incoming short- and longwave radiation, air and snow surface temperature acquired on 40x40m gridded plots using a handheld instrument, as well as snow depth data measured at the same grids.

Canopy structure information derived from hemispherical images is included for each all surveyed locations as well, and an overview of the field sites is provided.
