Ozone(O3)and Secondary organic aerosol(SOA)are important pollutants in theurban atmosphere.Benzene is one of the most important aromatic precursors,which couldproduce O3 and SOA in the presentence of
The frequent occurrence of regional air pollution makes it challenging to control.Based on sensitivity research performed with the Chinese Unified Atmospheric ChemistryEnvironment(CUACE)model and the
Particulate matter(PM)pollution has led to great scientific,governmental andpublic concerns due to its adverse effects on air quality and human health.Among all theconstituents in particle matter,orga
This study focuses on the importance of initial conditions in air-quality prediction.Assimilation experiments are employed using WRF-Chem model and Grid-point StatisticalInterpolation(GSI)for a 9-day
O3 is mainly produced by photochemical reaction of the nitrogen oxides(NO+NO2= NOx)emitted from vehicles and VOCs.H2O2 plays a role as a reservoir for amounts of HOx andNOx which triggers increasing o
Eighteen polycyclic aromatic hydrocarbons(PAHs)in PM2.5 collected near the NanjingOlympic Sport Center across the Asian Youth Games(AYG)period(from August 2 to August 28,2013)were analyzed using GC-MS
Traffic emissions are a significant source of airborne particulate matter(PM)inambient environments.These emissions contain an abundance of toxic metals and thus poseadverse effects on human health.In
Despite extensive efforts into the characterization of air pollution during the lastdecade,real-time characterization of aerosol particle composition above the urban canopy inmegacity Beijing has neve
Rice-wheat(R-W)rotation systems are ubiquitous in South and East Asia,which play an important role in modulating weather and climate.Long-term,continuous fluxmeasurements help better understand the se
