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.
Aerosol particles play important role in both global climate system and earth observation application. We have
developed a portable scanning Mie lidar, with the combination of spectrograph, active and passive earth observation
satellite data, and the ground sensor data, severe weather research and earth observation atmospheric correction work
could be conducted. To obtain more accurate aerosol information, we are developing a new multi-channel Raman lidar
system. Also we have developed a simulation model for system performance simulation and data simulation. In this
paper, the lidar system development, simulation modeling, and primary experimental work result will be described.
