Gravity

The research group maps the gravity field of the Earth both in Finland and globally, and studies its variation in time due to geophysical phenomena. For this we use both terrestrial gravimetry and data from satellite gravity missions like GRACE and GOCE. The results are used among other things, for the calculation of the geoid for GPS height determination, and for understanding geodynamical phenomena like postglacial rebound and the various aspects of global change.
