The main focus of this Priority Programme is to quantify terrestrial transport mechanisms and solar-terrestrial interactions through data analysis and modeling. The research programme builds on data from satellites on low-Earth orbits, such as CHAMP, GRACE, and GOCE. Special focus is given to the Swarm satellite mission.
This project is a part of the European Space Agency's (ESA's) Space Situational Awareness (SSA) programme, which includes the Space Weather (SWE) Segment. The objectives of this project are to coestimation of the definition and development activities within the Geomagnetic Conditions Expert Service Centre.

The aim of this study is to identify the role of atmospheric tides in the short-term variability of the global solar-quiet (Sq) current system. Atmospheric tides are global-scale waves generated mainly in the troposphere (<10 km) and stratosphere (<50 km). Tidal waves can propagate vertically into the ionosphere (>90 km), where the Sq currents flow. Understanding the tidal effect on the Sq current system is important for a better description of the Earth's magnetic field.
The project focuses on connecting and understanding long-term changes of the Earth’s magnetic field, paleomagnetosphere, solar variability and their implications on paleoclimate studies in an interdisciplinary manner, in particular considering geomagnetic excursions during the past 100 ka.
We study the configuration of the paleomagnetosphere and the solar variability over the past 100 ka, in particular during geomagnetic excursions, and their effects on the shielding against galactic cosmic rays and in situ cosmogenic nuclide production rates.
The projects aims at a description of the solar-cycle related variations of the large-scale magnetospheric contributions to the geomagnetic field, which can be used to eliminate this signal from decadal geomagnetic observatory or repeat station time-series for studies of internal core field secular variation.
