| Abstract: | Seasonal and latitude dependent corrections to the gravity and height anomalies are developed in order to account for the
neglect of the atmospheric masses outside the geold, when using Stokes’ equation. It is shown that the atmospheric correction
to gravity at sea level is almost constant, equal to0.871 mgals with a variation of2 μ gals whereas the height anomaly correction varies between −0.1 cm and −1.3 cm. Further, when the combined latitudinal/seasonal dependence is neglected in the atmospheric corrections, the maximum error
introduced is of the order of40 μ gals for the gravity corrections and0.7 cm for the height anomaly corrections. |
