ICESat-2 (short for Ice, Cloud and land Elevation Satellite) is an altimeter satellite able to retrieve information on sea ice topography. Using ICESat-2 ATL07 along-track sea ice heights, and a parameterization (Garbrecht. et al. 2002) that links sea ice topography with drag coefficients, monthly pan-Arctic drag coefficient maps have been produced. The figure shows data computed from April 2019 ICESat-2 ATL07 tracks (all three strong beams). Figures A and B show the averaged height and spacing of obstacles e.g., ridges, snow dunes, sastrugis, etc. The two parameters serve as the satellite-derived inputs for the Garbrecht et al. (2002) parameterization. C shows the sum of skin (drag associated to centimeter-scale roughness) and form (drag associated to larger distinct obstacles) drag coefficients. D shows the same map but with the form drag coefficients scaled by a regression that was derived between ICESat-2 ATL07 and Operation IceBridge (OIB) airborne topography data. The near-coincident OIB flights, used to derive the scaling factor, were flown in April 2019 in the area outlined by red in A. This scaling is necessary as ICESat-2 ATL07 smooths out some sea ice features due to sampling and spatial resolution limitations. More on this procedure and the resulting data set can be found in Mchedlishvili et al. (2023).
