Description

The data set contains manual snow depth measurements collected as part of the NASA SnowEx 2021 Time Series campaign. Data were collected at five out of seven Time Series study sites: Cameron Pass, Fraser Experimental Forest, and Senator Beck, Colorado; Boise River Basin, Idaho; and the Central Agriculture Research Center (CARC), Montana.

Snow depth measurements were collected with either an avalanche probe or a SnowMetrics depth probe, with location data recorded using either a Mesa2 tablet with a geode GPS or handheld Garmin GPS unit.
