Abstract: In order to achieve monitor for the spatial and temporal variation information of atmospheric aerosol all the time, a data acquisition and remote monitoring systems about a B/S mode of Mie scattering lidar was designed. The design is built an embedded system on ARM-Linux platform to realize the real-time atmospheric echo signal acquisition and get real-time processing of the atmospheric echo signal and display extinction coefficient curve Time-Height -Indicator (THI) figure by using Fernald method. The design based on a B/S architecture is remote monitoring system with monitoring platform-independent and location-independent features, which made the staff more convenient and intuitive understanding the information of the spatial and temporal variation of atmospheric aerosols from Mie scattering lidar day consecutive probing. Experiments show that the system is not only real-time display to extinction coefficient curve and THI figure, but also has good accuracy.
