Smoke aerosols, clouds, rainfall and climate : aerosols from biomass burning perturb global and regional climate

Objective

SMOCC's goal is to investigate a novel mechanism, by which atmospheric aerosols may affect climate. Anthropogenic aerosols, especially from biomass burning, increase the numbers of cloud condensation nuclei over the tropics. This reduces cloud droplet size, which prevents raindrop formation at shallower levels in the atmosphere and forces precipitation to farm at much higher elevations through ice processes. This modifies rainfall location and intensity, but also leads to large-scale changes in atmospheric dynamics, which impact climate world-wide, including Europe. Integrating atmospheric chemistry and meteorology, we will characterize the aerosol chemically and physically; identify properties responsible for cloud droplet activation; model the effects of cloud microphysics, and test the models by satellite remote sensing; and model the effects on climate dynamics to predict the impact of the proposed mechanism on climate and hydrology.
