Optimization of Emission Reduction Target in the Beijing-Tianjin-Hebei Region: An Atmospheric Transfer Coefficient Matrix Perspective.

ABSTRACT: In recent years, the problem of atmospheric pollution has been concerning in the Beijing-Tianjin-Hebei region, due to the frequent haze. It has become a significant issue to improve regional air quality through appropriate emission reduction measures. In this study, considering the regional atmospheric transmission of air pollutants, the WRF/CALPUFF model (the Weather Research and Forecasting model coupled with the California Puff air quality model) was used to describe the impact of each city's pollutant emissions on the concentrations of every city. Then, a new optimization model was designed to calculate the maximum allowable emissions of every city. The results showed that NOx and PM_2.5 emissions need to be reduced by 44% and 48%, respectively, in the traditional mitigation
