Joint Seminar: Multiphase processes in the atmosphere of the Earth system – from air pollution control to climate change mitigation
Multiphase processes play a vital role in the atmosphere system. These chemical, microphysical, optical and biological processes involving gases and other phases constitute a close link between human and ecological environment, and between air pollution and climate change. Despite of their importance, the intrinsic complexity of multiphase processes makes it one of the least understood areas in the atmospheric science. Current atmospheric models often oversimplify its description and parameterization. Here I show that such simplification may introduce large uncertainties with up to orders of magnitude discrepancy between model predictions and observations. Based on recent developments in the study of reactive nitrogen chemistry, aerosol phase transition and radiative forcing, I show how a better understanding of multiphase processes can not only fill the gap in science, but also help policymakers in the control of air pollution and mitigation of climate change.
