Pushing the limits: using ICESat-2 level 3A products to measure snow depth in remote, mountainous watersheds

Seasonal snowpack accounts for ~70% of the water supply in the western United States, and measuring snow accumulation and ablation remotely has long been a stated goal of NASA. The 2018 launch of ICESat-2, a spaceborne Lidar system, has offered unparalleled spatial and temporal coverage of mountainous terrain with unprecedented vertical accuracy. Data from ICESat-2 are used to measure seasonal snowpack in two watersheds of interest in Idaho. Accumulation and ablation measurements taken via ICESat-2 for the Dry Creek and Reynolds Creek experimental watersheds are compared to in situ and aerial lidar data. While the in situ and aerial lidar measurements are more precise and accurate, they are found to lack the temporal resolution and spatial coverage afforded by ICESat-2 data.
