Bathymetric Estimation and Fusion Using SWOT-derived Gravity Anomaly in the South China Sea

GRASWOT and GRASS are the SWOT drived-marine gravity anomaly and the SSV32.1 marine gravity anomaly model released by SIO, respectively. SWOT_BAT is the bathymetry model result obtained by GRASWOT, SS_BAT is the bathymetry model result obtained by GRASS, and BPNN_BAT is the final model obtained by training and fusing SWOT_BAT, SS_BAT, and Topo25.1 using BPNN combined with single-beam and multi-beam data. The grd2xyz module in GMT software can be used to convert and utilize models into textual data.

The data range is 112 ° E-118 ° E, 10 ° N-18 ° N.
