attribute NC_GLOBAL summary String ETOPO 2022, a global relief model with 15 arc-second resolution seamlessly integrating topographic and bathymetric data. The ETOPO 2022 model uses a combination of numerous airborne lidar, satellite-derived topography, and shipborne bathymetry datasets from U.S. national and global sources. ETOPO 2022 uses bare-earth topographic data from NASAs ICESat-2 and other vetted data sources to independently validate both the input datasets and the final ETOPO 2022 model. ETOPO 2022 is available in "Ice Surface" (top of Antarctic and Greenland ice sheets) and "Bedrock" (base of the ice sheets) versions. ETOPO Global Topography and Bathymetry. NOAA National Centers for Environmental Information (NCEI) data from a local source.
