Implications of RCP emissions on future PM2.5 air quality and direct radiative forcing over China

With rapid industrialization and urbanization over the past decades, China has experienced widespread air pollution induced by fine particulate matter with a diameter of 2.5 μm or less (PM2.5). To protect human health and meet the newly implemented annual PM2.5 target (less than 35 μg m-3), great efforts are needed to reduce emissions effectively. It is, therefore, essential to understand how future PM2.5 concentrations are affected by changes in anthropogenic emissions.
