O3, aerosol and CO2 are very important species in atmosphere. CO2 is a green-house gas with long life time. O3 and aerosols are short-lived air pollutants. They are radiative reactive species which will have impact on climate. On the other hand, they can interact with each other, thus variation of one species can have impact on other species. In China, CO2 is increasing stably in last 20 years and O3 is increasing sharply in last five years. Aerosol(or PM2.5) shows a significant decrease trend. In order to study on O3-aerosol-CO2 interactions, the regional climate chemistry models RegCM-CHEM and weather research forecast model wrf-chem were used to simulate the distribution of CO2, O3 and different kinds of aerosol. Especially, the interactions among the three species were investigated respectively. The talk will present some preliminary modeling results on this topic.

 

Brief Biography: Tijian Wang got Ph.D from Nanjing Institute of Meteorology in 2000 and now is a professor of School of Atmospheric Science, Nanjing University, China. He worked as a research scientist in University of Getoborg/Sweden, University of Iowa/USA, NCAR/USA and Hong Kong Polytechnic University during the some periods of 2000-2008. His research interests center around atmospheric environment and chemistry modeling in mesoscale, air pollution and climate change in regional scale, atmospheric deposition and air-soil exchange. He has publicated more than 250 papers in national and international journals.
