This paper focuses on estimating a new high-resolution Earth's gravity field model named SGG-UGM-2 from satellite gravimetry, satellite altimetry, and Earth Gravitational Model 2008 (EGM2008)-derived gravity data based on the theory of the ellipsoidal harmonic analysis and coefficient transformation (...
-6C2, EIGEN-6C4, GOSG-EGM in frequency domain has been done, which shows that SGG-UGM-1 is close to the reference models and that the coefficients lower than degree 220 of SGG-UGM-1 are more accurate than that of...

UGM-2 together with other models,such as European improved gravity model of the earth by new techniques(EIGEN)-6C4,GECO,EGM2008,and SGG-UGM-1(the predecessor of SGG-UGM-2).Compared to other models,the model SGG-UGM-2 shows a promising performance in the GPS/leveling validation.All GOCE-...
The present study deals with mapping of the crustal structure over the Central Indian Ridge (CIR) covering 3°S–11°S using SGG-UGM-2 Free-air gravity data. We have discussed the importance of mantle temperature correction along with Bouguer, sediment thickness, and curvature corrections to ...
This study presents a comprehensive analysis of the Garoua sedimentary basin (GSB) utilizing the high-resolution SGG-UGM-2 model, which offers a refined depiction of the Earth's gravity field. The primary objective was to elucidate the structural lineaments underpinning the basin....
