Outline of Final Research Achievements |
Knowledge of localized air quality within street canyons is important in urban areas with high-rise buildings that alter wind and pollutant transport. The purpose of this study is to construct a mobile lidar for profiling optical properties of near-surface aerosols along the street canyon while maintaining the safety condition of the laser beam. We tested the practical applicability of the proposed lidar for aerosol detection in the Tokyo Bay area and found the multi-layered structure near the surface before progressions of the convective mixing along with the increase in traffic.

Academic Significance and Societal Importance of the Research Achievements |
近年の都市大気環境問題は、広域汚染に加えて、住環境や健康被害を建物(~10 m)・街区(~100 m)スケールで考える環境影響評価が重要視されている。本研究課題で開発した前例のない高い時空間分解能での大気汚染物質分布を提供する技術は、大気汚染物質の予測精度向上のための評価や数値モデルへのデータ同化、都市大気環境の理解深化、それらの結果を反映した大気汚染対策や都市計画に貢献する。
