Abstract

Currently, satellite altimetry has rightfully taken its place among the methods of remote sensing of the Earth from space. The area of application of satellite altimetry is growing. In addition to the classical problems of geodesy, satellite altimetry data are actively used in many Earth sciences. The use of satellite altimetry data to compute marine gravity anomaly provides good results with relatively low costs. Those advantages make geodesists utilize this method as an alternative in geoid determination, especially over the seas. The issue of determining the characteristics of the gravitational field over the oceans according to satellite altimetry is considered. On the basis of the “remove-compute-restore” parameter, special software was developed and digital models of the Black Sea area (longitude: 36.1°–37.76°, latitude: 42.74°–44.38°) were constructed. The RMS of gravity anomalies from the EGM2008 data in this area does not exceed 6 mGal. Based on the methodology for processing altimetry measurement considered in this paper, it is planned to build a global geoid model within of the Global Ocean.

AB  - Currently, satellite altimetry has rightfully taken its place among
the methods of remote sensing of the Earth from space. The area of
application of satellite altimetry is growing. In addition to the
classical problems of geodesy, satellite altimetry data are actively
used in many Earth sciences. The use of satellite altimetry data to
compute marine gravity anomaly provides good results with relatively
low costs. Those advantages make geodesists utilize this method as an
alternative in geoid determination, especially over the seas.  The
issue of determining the characteristics of the gravitational field
over the oceans according to satellite altimetry is considered. On
the basis of the “remove-compute-restore” parameter, special software
was developed and digital models of the Black Sea area (longitude:
36.1°–37.76°, latitude: 42.74°–44.38°) were constructed. The RMS of
gravity anomalies from the EGM2008 data in this area does not exceed
6 mGal.  Based on the methodology for processing altimetry
measurement considered in this paper, it is planned to build a global
geoid model within of the Global Ocean.
