World ocean annual mean absolute geostrophic velocity on marine geoid of EIGEN‐6C4 from WOA13
This data set was established from two open sources: (a) geoid undulation (N) from EIGEN‐6C4, which is a static global combined gravity field model up to degree and order 2,190, and (b) ‘World ocean geostrophic velocity inverted from World Ocean Atlas ...

Multiband raster datasets in order to use global gravimetric models for the territory of the Republic of Kosova [PDF]
Due to current situation in Kosova with the national geoid, which is still under development, utilization of global EGM’s is more than necessary. In this research, multiband raster datasets with 1km spatial resolution of existing EGM 2008, 1996, and ...

Determination of correlation coefficient between geoid-to-quasigeoid separation calculated by the satellite data in Sjöberg’s equation and GPS/Levelling method [PDF]
In this paper, two techniques for calculating the geoid-to-quasigeoid separation are employed. One of them is GPS/Levelling customary method as a criterion where the geoid undulation and height anomaly are computed by subtracting the ellipsoid height ...
