The NASA Jet Propulsion Laboratory (JPL) Glacier and Ice Surface Topography Interferometer (GLISTIN-A) sensor was flown over the SnowEx study sites in Grand Mesa and Senator Beck Basin (labeled Telluride), Colorado in September 2016 (baseline, snow-off conditions) and in February 2017. The instrument was mounted in the wing pod of a Gulfstream-III jet. Ka-Band data from the GLISTIN-A sensor were collected along 14 flight lines flown between 27 September and 28 September 2016 and 63 flight lines flown between 09 February and 25 February 2017. All SnowEx GLISTIN-A data are stored and available for download from the JPL UAVSAR Data Search page. Find the SnowEx 2017 data on the JPL website by selecting “Ka-band” from the list of Band options and typing “Telluride, CO” or “Grand Mesa, CO” in the search box under Find.
