NGWOS Ground-Based Discrete Snowpack Measurements Data Release (ver. 2.0, March 2026)

Ground-based discrete snowpack measurements were collected during winter field campaigns starting in 2020. These data were collected as part of the U.S. Geological Survey (USGS) Next Generation Water Observing System (NGWOS) Upper Colorado River Basin project focusing on the relation between snow dynamics and water resources. This data release consists of three child items. Each child item contains snow depth, snow density, snow temperature, or snow water equivalent values measured discretely in the field. The data are provided in comma separated value (CSV) files. The data release was revised in 2026 with new discrete snowpack measurements of snow density and snow water equivalent and discrete snow depth data from 2023 to 2025. First posted June 2023 (contact author for original version files). Revised, March 2026, version 2.0.
