ATLAS/ICESat-2 L3B Monthly Gridded Dynamic Ocean Topography V004
Listed in NASA Earthdata CMR
ATL19 contains monthly gridded dynamic ocean topography (DOT) over midlatitude, north-polar, and south-polar grids derived from the along-track ATLAS/ICESat-2 L3A Ocean Surface Height product (ATL12).
Description
Monthly gridded sea surface height (SSH) can be calculated by adding the monthly gridded DOT and the weighted average geoid height also provided. Both single beam and all-beam gridded averages are available: single beam averages are useful for identifying potential biases among the beams, and the all-beam averages are useful in physical oceanography.
Simple averages, degree-of-freedom uncertainty averages, and averages interpolated to the center of grid cells are included, as well as uncertainty estimates.
