Description

The data set is a time-series of snow pit measurements obtained by the SnowEx community during the 2020 campaign. Between October 2019 and May 2020, data were collected from 454 snow pits at 12 regional locations throughout California, Colorado, Idaho, New Mexico, and Utah, USA. At each of the locations, between 1 and 11 sites covering a range of conditions (terrains, snow depths, etc.) were chosen for weekly snow pit observations. Also available are photos of the field notes and snow pit sites.

Note: As of July 2024, this data set is retired and no longer available for download. An updated version of this data is available for download as <a href="https://doi.org/10.5067/KZ43HVLZV6G4">SnowEx20 Time Series Snow Pit Measurements, Version 2</a>.
