Extended Data Fig. 3: CryoSat-2 sea ice thickness validation against airborne observations from the AWI IceBird Program 2016–2018.
From: A year-round satellite sea-ice thickness record from CryoSat-2
(a) Map of the airborne EM observations used for sea ice thickness validation. Three annotations in the Beaufort Sea mark the locations of the BGEP Moorings (see Extended Data Fig. 4). (b) Comparison of CryoSat-2 sea ice thickness observations with coinciding AEM measurements. The airborne data were averaged to 80-km scale before comparing with CryoSat-2. (c) Mean ice thickness difference between CryoSat-2 and the AEM as a function of the distance of observations from the coast. Map in panel a produced using MATLAB code from ref. 42.
