2026-07-01 Marine Gravity Anomaly Dataset Derived from Wide-Swath Altimeters (TG2 InIRA, SWOT KaRIn, and Their Fusion) over the Western Pacific Ocean and South China Sea doi:10.57760/sciencedb.space.03736 en This dataset provides high-resolution marine gravity anomaly grids over the Western Pacific Ocean and the South China Sea. The data are recovered based on the observations from two wide-swath altimeters, Tiangong-2 (TG2) InIRA and SWOT KaRIn, along with their fused data. The inversion process primarily adopts the remove-restore method, where deflections of the vertical (DoVs) are first derived from sea surface height gradients, and the final gravity anomalies are subsequently computed using the inverse Vening-Meinesz (IVM) formula. This dataset aims to serve as a valuable reference for the validation of multi-sensor wide-swath altimeter data fusion and high-precision marine geodesy research.
