Equal Area Scalable Earth Grid (EASE-Grid) Sea Ice Age, Version 4, 1984-2019

This data set provides weekly estimates of sea ice age for the Arctic Ocean derived from remotely sensed sea ice motion and sea ice extent. The temporal coverage for this data set is January 1984 through December 2019. For more recent data, see the Quicklook Arctic Weekly Equal Area Scalable Earth Grid (EASE-Grid) Sea Ice Age data product (https://nsidc.org/data/nsidc-0749). The main parameter for this data set is sea ice age, measured in years. Data are provided in georeferenced netCDF (.nc) format. PNG (.png) browse images are also provided. Each netCDF file contains 52 weeks of sea ice ages, coded as integers in a 722 x 722 gridded subset of the 12.5 km Northern Hemisphere EASE-Grid. Tschudi, M., W. N. Meier, J. S. Stewart, C.
