Short summary
Passive microwave (PMW) satellite data have been widely used to monitor Antarctic sea ice velocity (SIV) on a pan-Antarctic scale. We present a comprehensive evaluation of a PMW-derived Antarctic SIV by leveraging high-resolution SIV fields derived from synthetic aperture radar imagery. We found a widespread ~ 1 km d−1 underestimation of ice drift speed across the Southern Ocean, caused by optimal interpolation.
