With the constant exploration to the atmosphere and the attention to the air quality of the
living environment, the applications of micro-pulse lidar are more and more important. Micro Pulse
Lidar can be used to observe the distribution of atmospheric aerosol and analyse structure, spatial and
temporal evolution of the aerosol. The paper gives the introduction about the reference of micro-pulse
lidar which is researched in the laboratory. Through the precision optical design, the blind area of
Micro Pulse Lidar can be less than 45m. The portable requirement in the structure is implemented. The
software function of micro-pulse lidar includes: extinction coefficiency monitoring, tracking the
pollution source, distinguish spherical particular (fog) from no-sphercial particular(ice or dust)，
simulating the Mass concentration, scanning date integrating with GIS, and so on. The average height
of the boundary layer measured by micro-pulse lidar. The relationship between the cloud height and
aerosol echo signal can be seen from the data received from micro-pulse lidar and the peak is at 6KM.
By acquiring corresponding visibility values from probing different heights, a conclusion can be drawn
that visibility and extinction coeffcient is inversely proportionate. Take a 24 hour day as a circle and
divide it into several time periods. An atmosphere evolution diagram of the backscattering of the height
of atmospheric boundary layer and the atmospheric aerosol particles can be derived according to the
difference in sun radiation. Information like structure and the evolution characteristics of atmospheric
boundary layer, cloud height, cloud cover structure, atmospheric visibility and space particles obtained
by the laser radar detection provides a basis for the establishment of the correct atmospheric model. At
the same time because lidar can monitor the emissions of industrial soot and detect the law of diffusion
of environmental pollutants of the sky over cities, it is of great significance to the environmental
monitoring of the atmosphere and atmospheric science research.
