Airborne low-altitude snow depth on sea ice during aircraft flight P5_205_PAMARCMIP_2017_1704021401, Version 1


Airborne observations of snow depth on sea ice were made in March and April 2017 as part of the Polar Airborne Measurements and Arctic Regional Climate Model Simulation Project (PAMARCMIP) under the AWI IceBird campaign series. The data consist of six surveys spanning sea-ice covered areas in the Lincoln Sea, Central Arctic Ocean, as well as the Beaufort and Chukchi Seas. 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. The trajectory data contain the full and unfiltered data record with quality flags. Longer sections of altitude-flagged 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.
