This data set, obtained as part of the NASA SnowEx 2017 field campaign, contains in situ snow depth measurements along multiple transects at two locations in Colorado, USA: Grand Mesa, a snow-covered, forested study site about 40 miles east of Grand Junction; and Senator Beck Basin approximately 80 miles to the SSE of Grand Mesa.

The NASA IceBridge UAF Lidar Scanner L1B Geolocated Surface Elevation Triplets, Version 1 data set, available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), has been updated through 18 December 2017. This data set contains scanning laser altimetry data points of Alaska Glaciers acquired using the airborne University of Alaska Fairbanks (UAF) Glacier Lidar system beginning 19 August 2009.

In situ measurements of snow temperature, density, stratigraphy, grain size, wetness, depth, and snow water equivalent (SWE) are now available for 265 snow pits across two study sites in Colorado, USA: Grand Mesa, a snow-covered, forested study site about 40 miles east of Grand Junction and Senator Beck Basin approximately 80 miles to the SSE of Grand Mesa. These data were obtained during the NASA SnowEx 2017 campaign. To access the data, visit the data set landing page here: SnowEx17 Community Snow Pit Measurements, Version 1
