Development And Application of WRF(v4.1.2)-uEMEP(v5) Model at the City with the Highest Industrial Density: A Case Study of Foshan

Abstract. The study aims to develop and apply the WRF-uEMEP model to simulate air quality at the city scale, with a focus on Foshan, the city with the highest industrial density. The interaction between atmospheric diffusion and chemical reactions in different regions further complicates the modeling process. Therefore, this study proposes a multi-scale approach to build an urban air quality model with a resolution of 250 meters by integrating different models. The model takes into account the effects of urban structure and takes into account atmospheric diffusion and chemical reactions in different regions. The research process included model development, calibration, and validation using existing air quality data in Foshan. The study shows that the WRF-uEMEP model effectively captures the impact of urban structure on air pollutant processes. The simulation results reveal the spatial and temporal distribution of air pollutants in Foshan, providing valuable insights for urban air quality management.
