• On Wednesday, October 29 from 9:00 a.m. to 3:30 p.m. (US Mountain Time), this data set may not be available in the legacy data archive due to a planned system maintenance. Earthdata Cloud access will remain available for data sets that have migrated. Users of the SMAP near real-time products should use the NASA LANCE HTTPS File System for data access.

  • The NSIDC DAAC is retiring access to its legacy, on-premises data archive and transitioning to the NASA Earthdata Cloud as the primary data archive. View planned retirement dates here.

Overview

As of 23 September 2022, this data set is retired and no longer available for download. Per our agreement with the data provider, NSIDC only archives the most recent version of each of the ICESat-2 standard products and the version that preceded it. The most recent version is available from https://nsidc.org/data/icesat-2/data-sets

This data set provides time series of land-ice surface heights derived from the ICESat-2 ATL06 Land-ice Height product. It is intended primarily as an input for higher level gridded products, but can also be used on its own as a spatially organized product that allows easy access to height-change information derived from ICESat-2 observations.
