CryoSat-2 Level-4 Sea Ice Elevation, Freeboard, and Thickness, Version 1 (RDEFT4)
This is the most recent version of these data.
This data set contains estimates of Arctic sea ice thickness and concentration, ice freeboard and surface roughness, as well as snow density and depth, derived from the ESA CryoSat-2 Synthetic Aperture Interferometric Radar Altimeter (SIRAL). The data are provided daily on a 25 km grid as 30-day averages for the months between September and May.
