The ATLAS/ICESat-2 L3A Ocean Surface Height (ATL12) data set, accessible through the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), has been updated to Version 5. This global data set contains along-track sea surface heights relative to the WGS 84 ellipsoid at variable length scales over cloud-free regions. Estimates of height distributions, surface roughness, surface slope, and apparent reflectance are also provided. ATL12 is available 13 October 2018 to present.
