Global High-Resolution Fused Marine Gravity Field Product (V1)​

This global gravity field product is generated by fusing the new versions of the two most representative altimetry-derived marine gravity field models internationally—DTU21 and SIOv32.1—based on the corresponding relationship between the verification accuracy of JAMSTEC ship gravity data and water depth of SRTM15v2.4 model in the western Pacific Ocean. This product is a 1'X1' grid for global ocean gravity anomalies, covering latitude 90 degrees north and south and longitude from 0 to 360 degrees. This product contains three variables, where the variable lon represents longitude in degrees; The variable lat represents latitude in degrees; The variable grav represents a two-dimensional gravity anomaly grid, measured in milligals.
