Phys., 14, 2419-2429, 2014
UV radiation Ratio of VOCs/NOx A clear weekly cycle in the fine aerosol concentration was observed, Higher concentrations of aerosol on weekdays can reduce the UV radiation flux by scattering or absorbing, which leads to a decrease in the ozone production efficiency O3 PM Concentrations A smaller decrease in volatile organic compounds (VOCs; using CO as a proxy) and much lower NOx concentrations
VOC/NOx ratio, which can enhance the
regime areas.
