Abstract

The amount of thermal power generation has increased significantly in Japan since the Great
East Japan Earthquake in 2011, resulting in increase in emissions of air pollutants. This research evaluated
the impact of the emission increase on air quality in Kinki region, Japan by using the Community Multiscale
Air Quality model (CMAQ) driven by the Weather Research and Forecasting model (WRF). Three cases of
CMAQ simulations were conducted with emission data considering thermal power generation for the year
2010 and 2012, and without power plant emissions, using the meteorological field fixed to 2010.The
simulation for the year 2010 well agreed with observations. The emission increase caused higher air pollutant
concentrations around power plants, and the contribution of power plant emissions was up to 15 % of NO2
concentration in 2012.
