Abstract With the rapid growth of industries and population in India, increase of air pollutants emissions is expected and will result in higher pollution levels in future than nowadays without proper control measurements in addition to climate change. This study will investigate the effects of emission and climate change on concentrations of ozone and particulate matter (PM) in India, 2050 using the Community Multi-scale Air Quality (CMAQ) model. The current meteorology will be generated using Weather Research and Forecasting (WRF) model version 3.7.1 and the future meteorology will be generated using the same model under the Representative Concentration Pathways (RCP) 4.5, 6.0 and 8.5 emission scenario. The three future emission scenarios will be developed based on Emissions Database for Global Atmospheric Research (EDGAR) version 4.3 as following: no change case will directly use 2015 emissions for 2050, business as usual (BAU) case will use adjusted emissions in 2050 with proper factors to reflect the growth of industry and population, and controlled case will be based on potential control strategies. The differences in spatial and temporal variations of air pollutants between 2015 and 2050 will be analyzed and the contributions of emission change and climate change in three scenarios will be quantified.
