The dataset contains Heavy Lake Effect Snowfall (HLES) and related parameters from GEM outputs (RCP8.5, 10 km horizontal resolution, Laurentian Great Lakes region, driven by CanESM2 at the boundaries) and observation datasets. Observation data included are: interpolated to the model grid Daymet 2m air temperature and total precipitation, CIS-NIC ice concentration observations, and REA-Interim near-surface winds.
