Recent low-Earth orbiting satellite missions such as CHAMP, GRACE, GOCE and Swarm provide a wealth of data to study dynamic processes in the Earth and its space environment. They are used to investigate variations in Earth's interior, the atmosphere, the ocean, and in
near-Earth space. These variations affect in particular Earth's magnetic and gravity fields. Special emphasis is given to gain new insight from studying interactions of these processes.
The session invites contributions on any of the subjects, in particular by combining two or more aspects of magnetosphere/ionosphere and thermosphere/ionosphere coupling, magnetic field and gravity studies. Contributions involving complementary observations from other satellite missions and ground stations as well as empirical and physical models to gain better process understanding are likewise highly welcome.
