Paper Abstract

Owing to understanding the transportation and chemical reaction of the aerosols, it is important to observe the aerosol density, depolarization ratio, wind profiles, temperature profiles and water vapor density simultaneously. We have prepared several lidar systems for simultaneous measurement of these constituents and parameters. The polarization lidar consists of the frequency-doubled Nd:YAG laser and polarizer for measurement of density and non-sphericity of the aerosol. The wind lidar consists of the incoherent Doppler lidar using the frequency-doubled Nd:YAG and the iodine vapor filter for measurement of the wind profiles. The temperature lidar is realized by the rotational Raman lidar with the Mie scatter blocking filter. And water vapor profiles are measured by a vibrational Raman lidar using the frequency doubled Nd:YAG laser. We got preliminary results of these parameters in the aerosol layer.
