Description:
This gravimetric model for the Ukraine area was derived from terrestrial free-air gravity anomalies and Geosat altimeter data over the
Black and Azov Seas. A remove-restore procedure was adopted for the geoid computation, considering the NFME model as reference field.
This model was composed by a set of 5 central and 1417 non-central radial multipole, approximating the area under study better than OSU91A.
The residual gravity anomalies were approximated by a set of 296 radial multipoles, which were determined by using the Sequential Multipole
Analysis (SMA). Therefore the UFM model consists of 5 central and 1713 non-central radial multipoles. Finally the UFMC model was computed by
adjusting the UFM solution to the absolute gravity measurements of 7 stations located on the seashore. Both the UFM and UFMC models are referred
to the GRS80 reference ellipsoid and approximate gravity anomalies in the study terrestrial/marine area with an accuracy of 2 mGal.
