大気汚染物質の動態・拡散過程の研究 pp. 40-47 Technical Review: Pollutant diffusion/variations using 3-D coherent Doppler lidar measurement 髙島 久洋 Hisahiro Takashima |

Abstract The Doppler lidar is a powerful tool for direct observation of 3-D wind speed/direction. Combining observations of trace gas/air pollutants with the Doppler lidar allows us to understand the finer diffusion process of air pollutants. In this report, we present a study of pollutant diffusion over the Fukuoka urban areas using the MAX-DOAS trace gas profile and ground-based gas/aerosol observations combined with Doppler lidar wind observations. |
