Airborne low-altitude snow depth on sea ice during aircraft flight P6_217_ICEBIRD_2019_1904101401, Version 1


Airborne observations of snow depth on sea ice were made in April 2019 during the winter campaign of the AWI IceBird campaign series. The data consist of five surveys, some with overlapping segments at low and high altitude, spanning sea-ice covered areas in the Lincoln Sea, Central Arctic Ocean, as well as the Beaufort Sea. For each 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 4-5 meters for low-altitude flights and 7-9 meters for high-altitude flights. The trajectory data contain the full and unfiltered data record with quality flags. Longer sections of altitude-flagged data in the low-altitude data arise from calibrations of an EM sensor. Each snow depth value represents the average depth within the radar footprint that has a theoretical smooth surface cross-/along-track diameter of 2.6/1.0 m at low altitude and 7.2/5.1 m at the high altitude.
