7. Satellite Radar Altimetry for Determination of Geoid Undulations and Gravity Anomalies
Abstract : The sea level changes both temporally (due to dynamic effects) and spatially (due to sea bottom topography and inhomogeneities in the Earth's crust). Satellite radar altimetry is a remote sensing technique which can be used for e.g. determination of the instantaneous and mean sea level, and gravity anomalies at sea. READ MORE

8. Precise Gravimetric Geoid Model for Iran Based on GRACE and SRTM Data and the Least-Squares Modification of Stokes’ Formula : with Some Geodynamic Interpretations
Abstract : Iran is one of the most complicated areas in the world from the view of rough topography, tectonic activity, large lateral density and geoidal height variations. The computation of a regional gravimetric geoid model with high accuracy in mountainous regions, especially with sparse data, is a difficult task that needs a special attention to obtain reliable results which can meet the needs of the today geodetic community.

9. A height datum for Uganda based on a gravimetric quasigeoid model and GNSS/levelling
Abstract : This study is devoted to the determination of a high resolution gravimetric geoid model for Uganda based on the optimal combination of terrestrial and satellite gravity anomalies using the method of Least Squares Modification of Stokes’ formula with additive corrections. Specifically the study investigates the current status of the existing Uganda Vertical Network relative to the requirements of a modern height datum and includes a detailed evaluation and validation of terrestrial gravity data, several digital elevation models and some recent global geopotential models.

10. Study on the Earth’s Surface Mass Variations using Satellite Gravimetry Observations
Abstract : Our complex planet is continuously undergoing temporal and spatial changes. In this context, ongoing processes in the Earth subsystems (geosphere, biosphere, cryosphere, hydrosphere, and atmosphere) cause changes in the gravity field of the Earth across a wide range of temporal and spatial scales.
