Abstract
The size distribution function of aerosols in the lower atmosphere (_??_0km-2km)measured by the two-wavelength lidar technique is compared with the results determinedby an airborne optical particle counter. The comparison shows following facts, 1) The vertical changes of size distribution functions determined by the lidar techniqueshow good agreements with the results of the airborne particle counter in a qualitativesense.
2) The parameter of γ in the size distribution function for aerosol radius R, n(R)=AR-γ can be fully accurately determined by the lidar measurements, but the estimation of the other parameter A contains some uncertainty.
The remote sensing technique for the size distribution, function should contribute to the study of aerosol growth process, aerosol transformation process, aerosol transport process due to air motion in lower atmosphere, and so on.
