Airborne high-altitude snow depth on sea ice during aircraft flight P6_211_RESURV79_2018_1804100301, Version 1

Airborne observations of snow depth on sea ice were made in April 2018 as part of the RESURV79 (Re-survey of the 79° Glacier) campaign under the AWI IceBird campaign series. The data consist of one survey spanning sea-ice covered area in the Fram Strait. For the flight, the geolocated snow depth data from an airborne frequency-modulated continuous-wave ultrawideband radar using an algorithm based on signal peakiness are provided with a point spacing of approximately 7-9 meters. The trajectory data contain the full and unfiltered data record with quality flags. Each snow depth value represents the average depth within the radar footprint that has a theoretical smooth surface cross-/along-track diameter of 7.2/13.0 m.
