    Abstract
  • The key instruments and its equipment of the third generation movable atmospheric environment Lidar monitoring system (AML-3) were introduced, and the advantages of this system in monitoring the particles and gaseous pollutants described. The experiments focusing on the atmospheric environment issues and meteorological elements were carried out in Chinese Research Academy of Environmental Sciences (40.04°N,116.41°E). The results show that compared with the normal monitoring systems, the AML-3 has obvious advantages in integrated and movable observation of near-surface, vertical and slanting route profile distribution of normal pollutants concentrations and particle extinction coefficients, as well as the surface meteorological elements, such as temperature, relevant humidity, wind speed, wind direction and atmospheric pressure. The aerosol backscattering coefficients reach its highest value near the surface and gradually decrease with the altitude increase at the experimental site in Beijing; the aerosol concentration layer during the clear sky with strong winds is obviously higher than that during the clear sky with week winds. At the experimental place, when the relative humidity is low, the number concentration of particles has negative correlation relationship with relative humidity; meanwhile, when the relative humidity is higher, the number concentration of particles in atmosphere has positive correlation relationship with relative humidity.
