Abstract:
This dataset contains airborne radar data acquired using the AWI ultra-wideband microwave radar (UWBM) during the Arctic season of 2017 (2.-8. April 2017). The profiles extend over sea ice in the Beaufort and Chukchi Seas in the western Arctic as part of the Polar Airborne Measurements and Arctic Regional Climate Model Simulation Project (PAMARCMiP). The data were utilized to derive snow freeboard and snow depth measurements. The AWI UWBM radar operated in a quad-polarized high-resolution mode. The data are available as netCDF files (including waveforms and metadata), KML files of the profile line locations, and quicklook images of the radargrams. For every profile we provide four radar products (img_01, img_02, img_03, img_04), which correspond to the four polarizations (VV, VH, HH, HV).
