Description

ATL24 provides 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).
