• Relationships between Emission Reduction to Anthropogenic Burning Sources and Ambient Concentrations of Secondary Inorganic Aerosol in Greater Tokyo

抄録

The relationships between changes in secondary inorganic aerosol concentrations (SIA) and emission reductions in Greater Tokyo were investigated through numerical simulations. First of all, it was confirmed that the numerical model used in the simulations showed an acceptable performance in reproducing measurements. It was shown by analyzing the simulated results that both annual mean concentrations and high-episodic daily concentrations decreased with reduced emissions. The reduction of SIA concentrations appeared mostly in summertime, but the concentrations in wintertime increased with decreasing emissions in some cases. These changes in the SIA concentrations largely depended on the changes in nitrate concentrations.
