A new ATLAS/ICESat-2 L3A Along Track Coastal and Nearshore Bathymetry, Version 1 dataset is available at NASA’s National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). This product contains global along-track coastal and nearshore bathymetry, consisting of refraction-corrected seafloor and sea surface heights (orthometric and ellipsoidal heights and instantaneous depths), as well as associated uncertainties. The data are derived from ATLAS/ICESat-2 L2A Global Geolocated Photon Data (ATL03).
Delivery of new Suomi NPP data ceases on Nov. 2, 2026. Users should transition to alternative products.
