Airborne Lidar Aerosol Measurements.
Abstract
A least-square-fit technique was used to fit lidar range-corrected power returned, S(R), data to a straight line for lidar shots made from an aircraft. These fits were made for data over a range of 0.12 to 1.0 km, regardless of the goodness-of-fit. The large difference between the lidar results and the Knollenberg data needs to be explained. While the slope method does not appear to be a good way to obtain accurate backscatter and extinction data, differences between the lidar and Knollenberg data of the magnitude observed cannot be explained on this basis. Additional lidar-data-gathering flights would be useful to further test the results observed here. In particular, a wider range of the relative humidity values would be of interest. Also, longer horizontal runs and more accurate determinations of the time of the lidar shots should be made. Keywords includes: atmospheric aerosols, range-corrected power returned, least-square fit, Knollenberg backscatter coefficient, and lidar backscatter-to-extinction ratio.
