| Outline of Final Research Achievements |
We generalized effect of atmospheric stability on pollutant concentration in urban areas, and it enabled prediction of pollutant concentration by wind tunnel experiments (WT) or Computational Fluid Dynamics (CFD) only under neutral atmospheric condition. Unmanned automatic measuring system of gas concentration was developed, which drastically decreased laver for the WT. Field measurements, WT and CFD of gas dispersion in an urban area were conducted, which proved prediction accuracy of WT and CFD. Furthermore, appropriate calculation conditions for meso-scale simulation model were examined by comparison between observation data and calculated results. By using the appropriate conditions, seven years calculation was conducted. Using the calculated data, standard wind database for environmental assessment of pollutant concentration were prepared. Based on these research results, plan for reforming environmental assessment methods for pollutant concentration was proposed.
