Multi-wavelength lidar system for the characterization of tropospheric aerosols and clouds

Atmospheric Data Collection Lidar (ADCL) of the Center for Environmental Remote Sensing (CEReS), Chiba University, is a multi-wavelength lidar system designed for measuring tropospheric aerosols and clouds with ancillary data from ground-based aerosol measurement instruments. In this paper, we report on the concept of aerosol and cloud retrieval based on vertical, slant-path, and plan-position indicator (PPI) lidar measurements in combination with aerosol measurements conducted with a three-wavelength integrating nephelometer, an aethalometer, and a particle counter. It is expected that such a combined approach makes it possible to study the detailed features of aerosols in the troposphere, including the aerosol-cloud interaction.
