Portable Mie lidar for monitoring atmospheric aerosol extinction

A portable Mie lidar has been developed for both daytime and nighttime aerosol measurements. The overall structure and specifications of the portable Mie lidar are described. The primary observational aerosol extinction profiles at 532nm are also presented and discussed in this paper. Signals detected by portable Mie lidar can reach about 25km at nighttime and 15km at daytime. It can also be used to measure the thickness and peak extinction value of cirrus．
