In-situ snowpack physical properties in northeastern Canada (Québec, Nunavik, Nunavut)
Abstract
This data set is a compilation of in-situ snow cover measurements acquired during multi-site and multi-date measurement campaigns. It includes snow depth, bulk density and snow water equivalent data for each site and each measurement date. The period covered by the data is 2000-2019. For each site and date, the number of variables measured varies.
