Abstract

The observational studies of the distribution and movement of aerosols using a lidar network and surface observation networks are reviewed in this paper. This study was conducted for a project with the Grant in-Aid for Scientific Research on Innovative Areas entitled “Impacts of Aerosols in East Asia on Plants and Human Health.” Three-dimensional distribution and movement of aerosols were studied in various temporal and spatial scales using the lidar network, a surface monitoring network which includes mountainous areas, the existing air pollution monitoring network, and chemical transport models. The Raman lidar receivers for measuring the extinction coefficient profiles were added to the lidars in six primary stations of the network (AD-Net), and continuous observations were performed. In the intensive observation periods, aerosol sampling was carried out in the mountainous area, and analyses using transmission electron microscope (TEM) and energy dispersive X-ray (EDX) were performed to study the composition and mixing states of aerosols. A long-term data set of the lidar extinction coefficients for dust and air pollution aerosols was constructed and provided for the studies of the effects of aerosols on human health.
