This is the most recent version of these data.
Version Summary
Changes to this version include:
Data are provided in georeferenced netCDF format rather than ASCII and raw binary files
Merge 15 highest-weighted rather than 15 closest input vectors
Improved filtering of SSMI inputs
Each buoy provides one daily motion estimate instead of separate noon and midnight estimates
Monthly ice motion estimates are no longer provided

Overview

This data set contains daily and weekly sea ice motion vectors, as well as browse images representing the weekly data. Input data sources, derived from AVHRR, AMSRE, SMMR, SSMI, and SSMI/S sensors; IABP buoys; and NCEP/NCAR Reanalysis forecasts, used to generate the daily and weekly sea ice motion estimates are also included. For more recent data, see the Quicklook Arctic Weekly EASE-Grid Sea Ice Motion Vectors data set (https://nsidc.org/data/nsidc-0748).
