Version 3 of the ATLAS/ICESat-2 L3B Mean Inland Surface Water Data (ATL22) data set, accessible through the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), has been released. This data set contains mean water surface heights for transects over inland water bodies derived from ATLAS/ICESat-2 L3A Along Track Inland Surface Water Data (ATL13). Temporal coverage currently spans 14 October 2018 to 21 June 2023 and is updated regularly. Spatial coverage is global. Changes with Version 3 are detailed in Section 3 Version History of the user guide.
Version 2 of this data set will be retired from the NSIDC DAAC in six months. Upon retirement, data will no longer be accessible. All related documentation will remain available on the data set web pages for future reference.
