Polar Pathfinder Daily 25 km EASE-Grid Sea Ice Motion Vectors, Version 3

This data set provides daily sea ice motion vectors derived from a wide variety of sensors in both gridded and non-gridded (raw) files. For the gridded data, weekly and monthly mean fields are also provided for the entire time series—from November 1978 through May 2015. Browse images of these mean fields are also available.

Version Summary:
  • Eliminated unrealistic AVHRR and IABP buoy velocities
  • Improved browse images
  • Reprocessed SSMI fields using GDAL map transformations on the DMSP SSM/I-SSMIS Daily Polar Gridded Brightness Temperatures Data Set, NSIDC-0001
  • Used the Sea Ice Concentrations from Nimbus-7 SMMR and DMSP SSM/I-SSMIS Passive Microwave Data Set, NSIDC-0051, to mask ice extent
