This is the most recent version of these data.
Version Summary
Version Summary
Data are provided in georeferenced netCDF format rather than ASCII and raw binary files; Merged 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 and ERA5 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.
