Abstract
Gamma and lidar observations from a UAV were collected over two seasons from shallow, wind-blown, prairie snowpacks in Saskatchewan, Canada with validation data collected from manual snow depth and density observations. The data included herein includes the snow survey point observations, the gamma spectrometer count rates, and raster’s of snow depth (at 0.25m resolution) and snow water equivalent from combining lidar snow depth and manual snow density observations at 0.25 and 22.5m resolutions, and snow water equivalent directly from gamma observations at 22.5m. This dataset provides the means to test the ability of UAV-gamma spectroscopy to resolve the areal average and spatial variability of snow water equivalent directly. Data processing and analysis is described in the associated submitted manuscript:
