Project on Solar Effects on Chemistry and Climate Including Ocean Interactions (ProSECCO)

Subject Area Atmospheric Science
Term from 2005 to 2013
Project identifier Deutsche Forschungsgemeinschaft (DFG) - Project number 5453804
 
The objective of ProSECCO III is to study the impact of variations in solar activity on Earth in simulations with state-of-the-art climate model systems and observations. The project will address aspects of coupling processes from the upper atmosphere to the oceans. Like in the two preceeding phases (ProSECCO I and ll) the project is split into two parts investigating the impact of solar variability on the decadal time-scale (Part A) and on the centennial to millennial time-scale (Part B). In Part A, we will study three current research topics: a) the impact of decadal solar variability on the stratosphere, specifically the solar signal in stratospheric ozone and temperature, and the role of the Quasi-Biennal Oscillation (GBO), b) the tropospheric and climate response to the decadal solar forcing, and c) the role of atmosphere-ocean interactions for decadal solar and climate variability. We will perform and analyze simulations with the state-of-the-art chemistry-climate-model (CCM) MA-ECHAM5/MESSy. The new aspect of ProSECCO III will be the focus on atmosphere-ocean coupling processes and the implementation of a newly developed ocean-atmosphere CCM. In Part B, effects of solar variability on climate of different pre-industrial periods will be studied with the atmosphere-ocean model EGMAM, focussing on the period from the Maunder Minimum until today and the Holocene.
