High-Resolution Snow Depth on Arctic Sea Ice From Low-Altitude Airborne Microwave Radar Data
We present new high-resolution snow depth data on Arctic sea ice derived from airborne microwave radar measurements from the IceBird campaigns of the Alfred Wegener Institute (AWI) together with a new retrieval method using signal peakiness based on an intercomparison exercise of colocated data at d...
