The ATL03 product was designed to be a single source for all photon data and ancillary information needed by higher-level ATLAS/ICESat-2 products. As such, it also includes spacecraft and instrument parameters and ancillary data not explicitly required for ATL03.VIEW RELATED INFORMATIONhttps://doi.org/10.5067/ATLAS/ATL03.002DocumentationGET DATAhttps://nsidc.org/data/data-access-tool/ATL03/versions/2/Data Access ToolCEOS IDN DIFVERSION 9.92019-10-242024-01-25NSIDCVersion SummaryChanges for this version include:
<ul>
<li>Added the equilibrium tide as a parameter (/gtx/geophys_corr/tide_eq).</li>
<li>Corrected the ph_id_channel description.</li>
<li>Added additional ATLAS housekeeping/status values from ATL02 to the /atlas_engineering group to fully describe the ATLAS configuration state.</li>
<li>Adopted an improved inland water mask.</li>
<li>Added DEM height and flag at the 20m geolocation segment rate. DEM height (/gtx/geophys_corr/dem_h) is the best available height from one of several region-specific and global DEMs. The DEM flag (/gtx/geophys_corr/dem_flag) indicates the DEM from which the height was retrieved.</li>
<li>Added a composite flag for POD/PPD quality at the 20m geolocation segment rate. A non-zero value indicates a possibly degraded geolocation solution.</li>
<li>Updated default uncertainties (sigma_h = 30 m; sigma_along = 20 m; sigma_across = 20 m; sigma_lat ~= 0.00018 deg; and sigma_lon = 0.00018 deg) to better represent actual uncertainties in the ATL03 photon data.</li>
