Accuracy assessment of high and ultra high-resolution combined GGMs, and recent satellite-only GGMs – Case studies of Poland and Ethiopia
The launch of dedicated satellite gravity missions (CHAMP, GRACE, GOCE, and GRACE–FO), as well as the availability of gravity data from satellite altimetry and terrestrial/airborne gravity measurements have led to a growing number of Global Geopotential Models (GGMs) developed. Thus, the evaluation...

| description | The launch of dedicated satellite gravity missions (CHAMP, GRACE, GOCE, and GRACE–FO), as well as the availability of gravity data from satellite altimetry and terrestrial/airborne gravity measurements have led to a growing number of Global Geopotential Models (GGMs) developed. Thus, the evaluation of GGMs is necessary to ensure their accuracy in recovering the Earth’s gravity field on local, regional, and global scales. The main objective of this research is to assess the accuracy of recent GGMs over Poland in Central Europe and Ethiopia in East Africa. |
