• In recent years, a large amount of attention has been paid to the health effects of PM2.5 and the agricultural effects of tropospheric ozone as effects of air pollution. However, the effects of differences in the horizontal resolution of the chemical transport models used for the above effects have not yet been clarified. Therefore, this study calculates ozone and PM2.5 concentrations for fine-resolution regional scale and coarse-resolution global scale simulations using a chemical transport model (CTM). Furthermore, the model evaluates the compatibility of the observed concentrations and the impact on estimates of the agricultural and health impacts. The results showed slight variation in future global impact analysis with the acceptable resolution. However, depending on the region, the variation in the yield loss with the satisfactory resolution was considerable. Therefore, we conclude that a higher resolution of CTM could change the agricultural impact analysis for some regions but have little effect on others, and therefore, the change in the overall impact analysis is limited.
