Description:
The UQG2006 model is a gravimetry-only for the Ukraine
and Moldova area with a grid resolution of 2'x3'. It
is referred to the GRS80 ellipsoid and it was constructed from the
following two data sets: (a) digitized gravity anomalies from BGI and (b)
gravity anomalies in the Black Sea area derived from altimetry data of
TOPEX/POSEIDON, ERS-1, ERS
-2, JASON-1, ENVISAT, and GFO missions for
the period from 1992 to 2005 year. The remove-restore technique was applied
to get rid of the long wavelength constituent of the gravity field by using
the EIGEN-CG01C global model up to degree and order 360. Terrain reductions
were based on the 1'x1' DTM GEBCO. The prediction of the residual height
anomalies was performed by collocation with regularization, where the
regularization parameter is a weighting factor multiplied to the noise
covariance. Comparisons of the gravimetric UQG2006 quasigeoid with GPS/levelling
data show differences with a standard deviation smaller than 8 cm.
