Description

The data set provides digital terrain models (DTM), digital surface models (DSM) snow depth models, and canopy height models (CHM), derived from point cloud data (available as <a href="https://nsidc.org/data/SNEX_MCS_Lidar_Raw">SnowEx Mores Creek Summit (MCS) Airborne LiDAR Survey Raw, Version 1</a>) acquired by airborne lidar scanning. Data were collected as part of a multi-year effort to monitor monthly snow distribution over a 35 km² region of the Mores Creek Headwaters in the Boise Mountains of central Idaho between 2021 and 2025. Data acquisition in 2021 overlapped temporally with the NASA SnowEx 2021 field campaign.
