EGM08 is being developed using the best available terrestrial gravity from surface and airborne sources, gravity from satellite altimetry and marine sources over the oceans, and the latest GRACE‐derived satellite solutions. Critical to the success of this endeavour is the compilation of a complete and accurate 5′ × 5′ global gravity anomaly database that takes advantage of all the latest data and modeling for both land and marine areas worldwide. This paper will provide an overview of the data being used in the new model; describe the development of the EGM08 and show comparisons of the final model with independent truth data.Permalink:
