Abstract

AbstractThe Nested Air Quality Prediction Modeling System (NAQPMS) is a new-generation fully coupled Eulerian model independently developed by the Institute of Atmospheric Physics, CAS. It can simulate the behavior and predict the values of various air pollutants, including PM2.5. This study coupled NAQPMS with an aerosol microphysics module—advanced particle microphysics (APM) to form a category model of NAQPMS + APM, which can simulate the microdynamics of multi-scale aerosols. This model used a high resolution classification method to characterize the size distribution of aerosol particles, which not only shows the mass concentration of aerosol particles, but also the number concentration, its spectral distribution, and the mixing state of particles. The NAQPMS + APM model can provide data for detailed analysis of the microdynamics mechanisms of fine particle pollution.
