Bougueranomalie UTM32 100 m
Description
Bougueranomaly (completely topographically reduced open-air anomaly) at the surface of the earth, i.e. predicted gravity minus normal heaviness (Geodetic Reference System 1980) at terrain level minus the complete effect of the topography above zero level area, with standard density 2.67 g/cm³ and integration radius 100 km (deviating from the 167 km usual in geophysics).
The up-to-dateness of the data stock (2016) corresponds to that of the quasigeoid model GCG2016.
The spatial data set is the basis for the representation of the quasigeoid in WMS severity. For this purpose, the original grid of the GCG2016 was sampled with a 100 m resolution in UTM32 projection.

Gravity system: International Gravity Standardisation Net 1971 (Morelli et al., 1974)
Normal heaviness: Geodetic Reference System 1980 (Moritz, 1964), no consideration of atmospheric influence
Level reduction: Direct calculation of normal heaviness as a function of geographical latitude and NHN height by means of ball function development up to degree 8
Bouguer plate reduction: none
Terrain correction: Spherical calculation of the complete topographic effect (excl. indirect effect of topography on gravity) up to 100 km, digital terrain model with grid width 1" (approx. 25 m), cuboid method (Forsberg, 1984) near 5', outside Tesseroid method (Grombein, 2013)
Reduction density/level: Mainland 2 670 kg/m³/Bathymetry (North Sea, Baltic Sea, Lake Constance) 1 000 kg/m³, 0 m asl. NHN (DHHN92)
Grid processing: Interpolation by collocation (Forsberg et al. 2008), grid width 30“x 45“, resampling to grid width 3.6” x 5.4”; Projection on UTM32 grid with grid width 100 m
Unit: mGal = 10^-5 m/s-2
Up-to-dateness: 2016
