Abstract:
This dataset contains airborne radar data acquired using the AWI ultra-wideband microwave radar (UWBM) during the Arctic season of 2019 (2.-10. April 2019). The profiles extend over sea ice in the Lincoln Sea and Nansen Sound in the Arctic Ocean and overlap with the measurements in the Beaufort Sea in 2017. The survey flights were performed as part of the ICESat-2 Validation Data Acquisition and IceBird 2019 Winter campaign. 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).
