Description

This data set contains the results of a ground penetrating radar survey conducted at Grand Mesa, Colorado. Data include the two-way travel time, calculated snow depth, and calculated snow water equivalent. Data were collected between 08 February 2017 and 25 February 2017 as part of the 2017 SnowEx campaign.

The unprocessed, raw data are also archived at NSIDC (DOI: 10.5067/ZPOLBRHVWG5V).

Version Description

Updated the radar velocity used to convert radar travel time to snow depth; updated the assumed density used to calculate snow water equivalent, which is now provided in cm rather than mm; updated data files to no longer include column 12 (Transect #); and removed Week 3 data (21 February to 23 February 2017). Week 3 data (21 February to 25 February) was later added as part of a minor version update.
