Versions 7 of ATLAS/ICESat-2 L3A Sea Ice Height (ATL07), ATLAS/ICESat-2 L3A Sea Ice Freeboard (ATL10), and ATLAS/ICESat-2 L3A Ocean Surface Height (ATL12) are now available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). These data sets contain along-track sea ice height, sea ice freeboard and sea surface height (SSH) acquired by the Advanced Topographic Laser Altimeter System (ATLAS) instrument on board the ICESat-2 observatory.
Versions 6 of these data will be retired from the NSIDC DAAC in 6 months time. Upon retirement, data will no longer be accessible, but all related documentation will remain available on the data set web page for future reference.
