Abstract
Within the framework of the REAL GOCE project, one of the main objectives is the validation of the GOCE products. In this contribution, the focus is on the regional validation of the GOCE products by independent terrestrial data sets in Europe and particularly in Germany, including terrestrial gravity anomalies, height anomalies from the high-resolution gravimetric quasigeoid models EGG2008 and GCG05, and astrogeodetic vertical deflections. Differences between the terrestrial data sets and the available GOCE geopotential models, with envisaged accuracies of 1 mgal for gravity and 1-2 cm for geoid heights, both at a resolution of 100 km, are computed and analyzed. The progress with respect to the GRACE models and the impact on regional gravity field modelling is outlined.
