DynamicEarth - SPP 1788

Activity

blue arrow OVERVIEW

DynamicEarth - SPP 1788 is a Priority Programme established by Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) SPP ("SchwerPunktProgramme").

System Earth changes continuously. Variations of Earth's interior, the atmosphere, the oceans, and near-Earth space give rise to changes in global potential fields, particularly in Earth's magnetic and gravity fields. The underlying processes can be identified and studied through monitoring and analysis of fundamental geomagnetic and gravity parameters.

The main focus of this Priority Programme is to quantify terrestrial transport mechanisms and solar-terrestrial interactions. The research programme builds on data from satellites on low-Earth orbits, such as CHAMP, GRACE, and GOCE. Of particular importance is the multi-satellite mission Swarm. Variations of the potential fields can be measured across a broad spectral range of spatial and temporal scales. Other parameters can be analysed, as well as ground-based observations and modelling results, to complement the understanding of the system Earth. The key to successfully investigating the range of topics in this programme is a multi-disciplinary approach.

The focus of work will be on the following areas:

  • Geomagnetic field
  • Gravity field
  • Current systems of the ionosphere/magnetosphere
  • Thermosphere/ionosphere.
