    keyword : PM2.5, Aerosol,Process analysis
  • Verification of an algorithm to retrieve four aerosol components using multi-wavelength Mie-Raman lidar and the analysis of the optical properties and aerosol components at Fukuoka, Okinawa, and Toyama.
    keyword : multi-wavelength Mie-Raman lidar, Mixing state of aerosols, Scattering Aerosol, Black Carbon, Mineral Dust, Sea Salt,

    keyword : Asian Dust, decreasing trend
  • Development of regional online coupled meteorology and chemistry model and the analysis of feedback effects between ozone and PM2.5
    keyword : online coupled meteorology - chemistry model

    keyword : Numerical model
  • Long-term Variation of Asian Dust and Related Climate Factors
    keyword : Asian Dust, Long-term variation, Regional numerical model
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.
