Atmospheric boundary layer observations based on raman lidar

The structure of atmospheric boundary layer and its changes during the night at Wuhan in china are observed based on a Raman lidar. The heights of the mixed layer and the entrainment zone are measured by the visual inspection method and the SBH99 method. The SBH99 method is also improved to be based on aerosol extinction coefficient, which can avoid the errors brought in calculating the backscatter coefficient. The results indicate that the Raman lidar system has good ability to detect atmospheric boundary layer.
