Abstrakt EN: Numerous global gravitational field models have already been derived from GOCE satellite gravitational gradiometry mission. Generally, these differ by the harmonic analysis approach and the time span of exploited measurements. Quality of individual solutions is assessed by validating of the global gravitational field models with respect to independent datasets. Global gravitational field models based on the time-wise and the direct approach are validated in this contribution. All five releases are compared with respect to height anomalies, deflections of the vertical and gravity anomalies over the continental part of Norway. The spectral enhancement method is applied to overcome the spectral inconsistency between the gravitational models and the terrestrial data.
