Ammonia, (NH3) is one important precursor of inorganic fine particles; however, knowledge of the impacts of NH3 emissions on aerosol formation in China is very limited. In this ,study,, we have developed China’s NH3 emission inventory for 2005 and applied the Response Surface Modeling (RSM) technique upon a widely used regional air quality model, the Community Multi-Scale Air Quality Model (CMAQ).
