原始语种摘要: Although stringent emission mitigation strategies havebeen carried out since 2013 in Beijing–Tianjin–Hebei (BTH), China, heavyhaze with high levels of fine particulate matter (PM 2.5 ) stillfrequently engulfs the region during wintertime and the nitrate contributionto PM 2.5 mass has progressively increased. N2O5 heterogeneous hydrolysis is the most important pathway of nitrateformation at nighttime. In the present study, the WRF-Chem model is appliedto simulate a heavy haze episode from 10 to 27 February 2014 in BTH toevaluate contributions of N2O5 heterogeneous hydrolysis tonitrate formation and effects of organic coating. The model generallyperforms reasonably well in simulating meteorological parameters, airpollutants,...
