Abstract

In the context of the regional gravity field modelling, the smoothing effect of the topographical correction on the high-frequency part of the gravity signal is well documented. In this study, the effect of the long-wavelength topographic correction on the low-degree Earth's gravity potential and attraction is investigated. For this purpose, the Earth's gravity field and the topography-corrected gravity field are compared for various spectral resolutions. The topography-corrected gravity field is obtained from the low-degree Earth's gravity field after subtracting the long-wavelength gravitational field generated by the topography. The Earth's gravity field is computed from a global geopotential model (GGM). The gravitational field generated by the topography is modelled from a global elevation model (GEM), adopting the constant topographical mass-density distribution.
