Abstract

In studies of the internal boundary layer, it is important to make the lidar both eye-safe and capable of measuring near range extinction to high accuracy. The inversion of data is much more challenging due to the weaker signal from an eye-safe lidar. The method of inversion employed in this paper is the Fernald's method. Because the digitization system is capable of obtaining returns in the time interval of a few seconds, formal statistical analysis and error propagation are introduced in the inversion. Different weighting schemes are used during the averaging of the inversion and the results from scattered cloud data as well as pure aerosol profiles will be discussed. Results from several sites and under different meteorological conditions will be reported.
