The Polar Pathfinder Daily 25 km EASE-Grid Sea Ice Motion Vectors, Version 4 data set, available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) has been updated through 31 December 2022. This data set provides daily and weekly sea ice motion vectors including browse images of the weekly data.
