Abstract: The interpretation of the gravity field in the 2D and 3D space requires an accurate Bouguer gravity anomaly map. This requirement is of particular importance, when different techniques, instrumentation and data processing methods have been used in different parts of the area of interest. This paper presents the Bouguer gravity anomaly map of the CELEBRATION 2000 countries (Austria, Czech Republic, Hungary, Poland and Slovak Republic) and reports on the calculation of Bouguer gravity data. The gravity map will serve as basis for 2D and 3D modeling of the gravity field in the CELEBRATION 2000 region (45^o–54^o latitude and 12^o–24^o longitude). To avoid truncation problems in the following quantitative interpretation, the map area consists of both the CELEBRATION 2000 countries and adjacent areas. Due to different average station density of gravity measurements in the countries (Austria — 1 station/9 km², Czech Republic — 1 station/2.6 km², Hungary — 4 stations/km², Poland — 2.74 stations/km² and Slovak Republic — 5 stations/km²) the gravity data were interpolated to grids by using different spacing and projection in each country. In the entire CELEBRATION area the average station density is approximately 2.4 stations/km² and the gravity data set contains more than 1,620,000 measurement points. Additionally, the most important regional gravity anomaly patterns of the map are presented with commentary.
