Previous versions of multiple ATLAS/ICESat-2 along-track data sets will be retired from the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) on 26 February 2024. After this date, access to the data will no longer be available. Data set documentation will remain accessible for future reference. We recommend using the latest versions of these data sets, which have been available since August 2023. Version-specific details can be found under “Version Summary” on each data set’s web page. Additionally, a version history is included in Section 3 of the User Guides.
