NSIDC DAAC Updates Sea Ice Motion Vectors Data Set

Version 3 of the Polar Pathfinder Daily 25 km EASE-Grid Sea Ice Motion Vectors data set is now available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). The data was updated through 31 May 2015. The following changes were made to the data set:

  • Eliminated unrealistic AVHRR and IABP buoy velocities
  • Extended buoy ice motion estimates to the present
  • 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 Ice concentration estimates greater than 15 percent from the Sea Ice Concentrations from Nim bus-7 SMMR and DMSP SSM/I-SSMIS Passive Microwave Data Set, NSIDC-0051, to indicate where ice extent is present.
