Global marine vertical deflection model SDUST2025DOV_SWOT and gravity anomaly model SDUST2025GRA_SWOT derived from SWOT/KaRIn data using local geoid fitting method

Le résumé fourni par la source

Description of the SDUST2025_SWOT Dataset: The SDUST2025_SWOT compressed package contains three NetCDF (.nc) files: north_SDUST2025DOV_SWOT.nc, east_SDUST2025DOV_SWOT.nc, and SDUST2025GRA_SWOT.nc. The file north_SDUST2025DOV_SWOT.nc contains the meridian component of the global marine deflection of the vertical (DOV), while east_SDUST2025DOV_SWOT.nc contains the prime vertical component of the global marine DOV. The file SDUST2025GRA_SWOT.nc contains the global marine gravity anomaly model. All three data files cover the region spanning longitudes 0°–360° and latitudes −77.6°–77.6°, with a grid resolution of 1′ × 1′. In the two DOV files, values over land areas are filled using the reference DOV values derived from the XGM2019e_2159 gravity field model.In the gravity anomaly file, values over land areas are filled using the reference gravity anomalies derived from XGM2019e_2159.The reference ellipsoid is the WGS84 ellipsoid. The unit of the DOV data is μrad, and the unit of the gravity anomaly data is mGal.
