USE OF THE UNB_TopoDens MODEL FOR LOCAL MODELLING OF CHOSEN GRAVITY FIELD PARAMETERS IN THE WESTERN CARPATHIANS

Popis výsledku v původním jazyce

The latest, global density model of topographical masses (UNB TopoDms model) was used to determine complete Bouguer anomalies and the differences between geoid undulations and height anomalies in an area of the Western Carpathians, within the Polish-Slovak-Czech border region. The ranges of the calculated values are between approximately -74 and +23 mGal for Bouguer anomalies and -10 and +5 cm for differences between geoid and quasigeoid heights. Calculations were also performed for constant densities of topographical masses (2200, 2500 and 2670 kg/m(3)). The results show significant differences due to the various densities adopted for the calculations. For example, differences between the version using densities from the UNB TopoDens model and the version using a constant density of 2670 kg/m(3) ranged between -3.4 mGal and +37.5 mGal, for Bouguer anomalies, and between -0.5 cm and +7.4 cm for differences between geoid undulation and height anomalies. It has also been shown that, for high mountain areas, differences between geoid and quasigeoid height should be determined on the basis of exact formula (not on the basis of Bouguer anomalies).
