Abstract
The Mie scattering lidar data acquisition and processing system based on LabView graphical programming software platform and data acquisition card (PicoScope 54444B) was developed. By calling PicoScope 5444B dynamic link library, atmospheric return signal data can be acquired and displayed. The Klett method was used to retrieve aerosol extinction coefficient profile and its' time-height-indication (THI) figure. Some preliminary experiments have been carried out to verify the feasibility of data acquisition and processing system. The results show that the system can process and display the atmosphere return signals, aerosol extinction coefficient and THI with good real-time performance and reliability, and it is convenient to understand the temporal and spatial evolution of atmospheric aerosol and cloud.
