2026-01-15 Global High-Resolution Marine Gravity Field Product (FUSION_V1.0) doi:10.57760/sciencedb.space.02951 en Based on the JAMSTEC local high-density ship gravity data in the western Pacific Ocean (120°E–170°E, 0°–50°N), the correspondence between the errors of satellite altimetry-derived gravity models (DTU21 and SIOv32.1) and water depth from SRTM15+v2.4 was established. A weighted fusion method was applied to generate a global high-resolution marine gravity field product FUSION_V1.0 with a 1′×1′ grid. The product provides seamless coverage from 90°S to 90°N and 0° to 360°E, stored in NetCDF format with variables for longitude, latitude, and gravity anomaly. This dataset serves as a high-quality foundation for seafloor topography recovery, marine geophysical research, and related space science application.
