A global marine bathymetry-derived gravity model SWOTBatGRA computed using the SWOT data

SWOTBatGRA is the first global marine bathymetry-derived gravity model computed using the Surface Water and Ocean Topography (SWOT) data. SWOTBatGRA focuses on enhancing short-wavelength signals at spatial scales finer than those resolved by altimetric gravity data. SWOTBatGRA maps the global marine gravity field (80°S~80°N, 0°E~360°E) at a spatial resolution of 1 arc-minute. The computation of SWOTBatGRA is based on the BathDNN25, developed by the University of Newcastle, Callaghan, Australia, using the SWOT gravity data (Salajegheh et al., 2025). SWOTBatGRA comprises five components: gravity anomaly (SWOTBatGRA_GRA.nc), gravity disturbance (SWOTBatGRA_GD.nc), quasi-geoid height (SWOTBatGRA_QG.nc), and north and east components of the deflection of the vertical (SWOTBatGRA_DOVN.nc and SWOTBatGRA_DOVE.nc).
