Gridded snow depth and snow water equivalent data (2020-2023) for eight watersheds in Southwest British Columbia, Canada

This dataset contains gridded snow depth and snow water equivalent (SWE) data for eight watersheds in southwest British Columbia, Canada, along with associated field observations. These data were generated in association with the following publication: Bisset, R., Floyd, W.C., Menounos, B., Bishop, A., Marchenko, S., Fisk, G., Cebulski, A., Marshall, P., Heathfield, D., Beffort, S., White, R., Gonzalez Arriola, S., Viner, N. (2026) Snow water storage within eight Pacific Coastal watersheds in British Columbia (Canada) inferred from four years of airborne lidar data. Water Resources Research. https://doi.org/10.1029/2025WR040837 More specifically, this dataset includes: Monthly/sub-monthly gridded snow depth data, for the snowmelt season each year between 2020 and 2023, generated based on airborne lidar data acquired by the Hakai Airborne Coastal Observatory. Monthly/sub-monthly gridded snow water equivalent data for the snowmelt season each year between 2020 and 2023, generated based on airborne-lidar-derived snow depth and modelled snow density. In-situ observations of snow depth and density collected during the snowmelt season each year between 2021 and 2023. Associated metadata, including variable descriptions and data formats, is provided in the accompanying README files. Further details on the methods used to generate this dataset are available in the publication referenced above.
