Satellite based global gravity field models represent EarthпїЅs long-wavelength static or time-variable gravity field. Their progress and development in the recent years has been induced by successful satellite missions, such as GOCE, GRACE and CHAMP and this will continue in the future missions. Resolution and agreement with quality terrestrial data are two attributes that indicate potential usability of each model. Maximum degree of spherical harmonics determines resolution of the satellite-based models. Agreeme...

Topographic and topoisostatic reductions of gravity field measurements are important in geodesy and geophysics. Reductions filter high frequencies from gravity which are then used in geoid modelling or investigations of the EarthпїЅs structure. Practical computations of reductions are performed using digital elevation/bathymetric models as input data and some approximation scheme of the EarthпїЅs structure. The main parameters describing the EarthпїЅs structure are crustal, mantle and water density, density contra...

The land cover changes of the area result from both nature-induced activities that are sometimes indirectly caused by human influence, and direct human-induced activities such as land use change, deforestation, city expansions, and other. Therefore, the land cover change can indicate climate changes of the geographic area as well as the change of the socio-economic factors. This study aims at analyzing the land cover change over the territory of the Republic of Croatia from 1990 onwards. The study is based on CORI...

A rise of a mean global sea level recorded during the 20th and 21st century is one of the most important indicators of climate change, which induces the thermal expansion of the oceans (steric effect) and ice melting. The mean rates of global sea level rise are estimated at around 3.1 mm a year. Those rates are routinely calculated from tide gauge measurements and satellite altimetry. However, regional rates that are driven by local geophysical processes can vary significantly. Thus, the impact of sea level change...
