ATLAS/ICESat-2 L3B Daily and Monthly Gridded Sea Ice Freeboard, Version 5, ATLAS/ICESat-2 L3B Daily and Monthly Gridded Polar Sea Surface Height Anomaly, Version 4, and ATLAS/ICESat-2 L3B Slope-Corrected Land Ice Height Time Series, Version 7 are now available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). These data sets contain higher level products derived from the Advanced Topographic Laser Altimeter System (ATLAS) instrument on board the ICESat-2 observatory: Sea ice freeboard heights and sea surface anomalies (ATL20 and ATL21) and time series for land ice heights (ATL11).
Previous versions 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.
