Current and Past Project

We will observe atmospheric aerosols from the main air pollutant sources in Asia using a newly developed multi-wavelength Lidar system located in three sites in Japan. This new Lidar system is designed to retrieve the composition of aerosols including black carbon, air pollutants, mineral dust and sea salt based on the measurement of the aerosol extinction coefficient, backscatter coefficient and depolarization ratio. We are planning to make multi-year continuous Lidar observations. These observations will generate a 5-D aerosol distribution database used to develop a new data assimilation model. Based on this integrated analysis, it will be possible to provide a detailed aerosol re-analysis field covering all of Asia.
