摘要：

Vertical profiles of the volume backscatter and extinction coefficients of the atmospheric aerosol have been derived from lidar measurements. The analysis assumes a horizontally uniform atmosphere, in which case the attenuation between the lidar and a fixed height is proportional to cosec θ, where θ is the angle of elevation. Observations at two angles of elevation thus suffice to determine the attentuation and hence the true backscatter coefficient. Two examples, based on observations at several angles of elevation, are presented to illustrate the technique. © 1969.
