The Senate of the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) has initiated the Priority Programme “Study of Earth System Dynamics with a Constellation of Potential Field Missions (DynamicEarth)“ (SPP 1788). The first funding period spans three years from early 2015 to 2018.

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, launched in November 2013. Three identically constructed satellites are equipped with a complimentary set of instruments to survey potential fields and fundamental physical parameters. 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 multidisciplinary approach. If possible, successful proposals should cover two of the main fields of work to emphasise the interdisciplinarity of this programme. The focus of work will be on the following areas:

·         geomagnetic field: study of its dynamics and evolution; analysing its different contributions, including the Earth’s core, mantle induction, lithosphere, and oceanic currents; geodynamo simulations and their link to the observations

·         gravity field: global variations of mass and mass balances, interaction and exchange mechanisms (hydrological cycle, ice melting in the polar regions, sea-level fluctuations, groundwater, relationship with anthropogenic influences, tides of oceans and atmosphere), length-of day variation, and high-resolution models of the gravity field

·         current systems of ionosphere/magnetosphere: ionospheric current systems from low to high latitudes, near-Earth verification of magnetospheric currents, field-aligned currents (FACs) – coupling of ionosphere and magnetosphere, contributions of ionospheric currents to the energy budget of the atmosphere

·         thermosphere/ionosphere: quantification of solar contributions (EUV, solar wind) and influence of the lower and middle atmosphere (waves and tides) on the variability of the upper atmosphere, interaction between ionospheric plasma and neutral gas, understanding and predicting ionospheric and atmospheric irregularities from equatorial to polar latitudes (e.g. signal disturbances in communication and navigation)

Research proposals for the first three-year funding period are now invited and can be submitted by 8 October 2014 (deadline). All proposals should be submitted in English and follow the guidelines in DFG form 50.05 (Priority Programmes) and 54.01 (Project Proposals). Please include a title page with your name, your address, and the title of your project in your application.
