Abstract
The vertical crustal displacements and temporal variations of the gravity field within the Baltic Shield are considered based on a joint analysis of observations from global navigation satellite systems and data from the GRACE/ GRACE-FO satellite missions. An increased rate of geoid uplift is noted in the zone of junction of the Baltic Shield with the East European Platform. It is shown that the region of increased rate of geoid uplift is associated with a band of lateral compression, within which the redistribution of gravitating masses can lead to additional anomalies of the gravity field, thereby explaining the noted feature in the ratio of variations in the gravity field and vertical motions of the earth's surface. The importance of taking into account both vertical and horizontal motions when jointly analyzing satellite geodetic and gravity-inertial data to study the geodynamics of regions of postglacial isostatic rebound is noted.
