TPChange – The Tropopause Region in a Changing Atmosphere – DFG TRR 301

Projections of climate change rely on an adequate representation of UTLS processes and their feedbacks in climate models. In the Collaborative Research Centre TPChange this will be addressed by a combination of field measurements, laboratory studies, theoretical approaches, and multiscale numerical modelling. Based on an improved understanding of relevant processes at different scales, we will develop parameterisations to improve state-of-the-art climate models. Our goal is to specify the impact of UTLS processes on composition, dynamics and ultimately on future climate and climate variability.

Earth System Chemistry integrated Modelling (ESCiMo)

Within the “Earth System Chemistry Integrated Modelling (ESCIMo)” initiative chemistry-climate-simulations are planned by the MESSy Consortium with the ECHAM/MESSy Atmospheric Chemistry (EMAC) model for special topics related to the national project of the DFG-Forschergruppe SHARP (Stratospheric Change and its Role for Climate Prediction) and the international IGAC/SPARC Chemistry-Climate Model Initiative (CCMI). These simulations will be carried out in support of upcoming WMO/UNEP ozone and IPCC climate assessments and will help to answer emerging science questions as well as to improve process understanding. To meet these scientific needs, the CCMI community with active support from SHARP scientists jointly defined new reference and sensitivity simulations.
