The C8 project aims to improve the understanding of aerosol and cloud processes and their representation in regional and global climate models. We have developed a new numerical method that consistently computes atmospheric trace gas and aerosol chemistry, and can be applied to compute the initial stage of cloud formation. It will allow for a direct coupling in climate models between aerosol chemical composition, being influenced by pollution emissions, and the continuum between hazes and clouds. The project focuses on the Mediterranean region because it is a hot spot in climate change exposed to drying and air pollution. By simulating realistic meteorological conditions at high spatial resolution our method will be tested against observations. The project is part of the Energy, Environment and Water Research Centre, in cooperation with the Max Planck Institute for Chemistry in Mainz, and will help assess human impacts on air quality and climate.
