An intercomparison of Arctic ice drift products to deduce uncertainty estimates
We made an intercomparison of four low-resolution remotely sensed ice-drift products in the Arctic Ocean (ice drift products from OSISAF, CERSAT, Kimura et al., 2013 and NSIDC). The purpose of the study is to examine the uncertainty in space and time of these different drift products. The ice drifts...
