/vsicurl/https://rmbl-sdp.s3.us-east-2.amazonaws.com/data_products/basemaps/UER_snowdepth_basemap_2018_v3.tif en dataset This is a styled basemap showing snow depth on March 31st, 2018 derived from repeat LiDAR data collection by the Airborne Snow Observatory. This dataset is derived directly from: Painter, T. 2018. ASO L4 Lidar Snow Depth 3m UTM Grid, Version 1. Boulder, Colorado USA. NASA National Snow and Ice Data Center Distributed Active Archive Center. doi: https://doi.org/10.5067/KIE9QNVG7HP0. Small areas outside of the UER region, but within the extent of this map had missing data. These gaps were filled with linear regression relating 2018 and 2019 ASO snow depths (where one map was available), or regressions related snow depth to elevation (where neither 2018 nor 2019 data was available). Peak snow depths in 2018 were near the 20th percentile of the long-term average estimated from the Butte SNOTEL station. The color scale ranges from <20 cm (gray), through red (20 - 100 cm), yellow (100 - 200 cm), green (200 - 300 cm), and blue (300 - 400+ cm).
