Abstrakt EN: Based on reprocessed GOCE gravitational gradients, that are spectrally filled in with a long-wavelength signal from GRACE/GOCE models, we provide global grids of gravitational gradients in the local north-oriented frame. These grids have the equiangular resolution of 30 and 15 arc-min that correspond to 360 and 720 in terms of spherical harmonic degree, respectively. The signal content of the data grids is analyzed with respect to that provided by state-of-the-art GRACE/GOCE Earth gravitational models. Grids of gravitational gradients reduced for effects of topographic, sea water, continental ice as well as sediments and crustal layers can be then used for geodetic and geophysical applications. These data products represent a particular output from the STSE GOCE+ Theme 2 project ?Towards a better understanding of the Earth?s interior and geophysical exploration research? funded by ESA.
