New version available: Polar Pathfinder Daily 25 km EASE-Grid Sea Ice Motion Vectors

The Polar Pathfinder Daily 25 km EASE-Grid Sea Ice Motion Vectors, Version 4 data set is now available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). Version 4 of this data set includes improved filtering of the SSMI inputs, an update to the method for merging the input ice motion vectors, and an update to the averaging of the input buoy data. This data set provides daily and weekly sea ice motion vectors including browse images of the weekly data. The source data used to generate the daily and weekly ice motion estimates are derived from AVHRR, AMSRE, SMMR, SSMI, and SSMI/S sensors; IABP buoys; and NCEP/NCAR Reanalysis forecasts. The data are now provided in NetCDF format and extend through December 2018.
