摘要

There is a dense network of torsion balance stations in Hungary, covering an area of about 40000 km~2. These measurements are a very useful source to study the short wavelength features of the local gravity field, especially below 30 km wavelength. Our aim is thus to use these existing torsion balance data in combination with gravity anomalies. Therefore a method was developed, based on integration of horizontal gravity gradients over finite elements, to predict gravity anomaly differences at all points of the torsion balance network. Test computations were performed in a Hungarian area extending over about 800 km~2. There were 248 torsion balance stations and 30 points among them where Δg values were known from measurements in this test area.
