Lidar Observations of Smoke and Dust Clouds at 0.7-Micrometer and 10.6-Micrometer Wavelengths.
Abstract
An experimental program was conducted for the purpose of deriving basic data required to determine the capabilities of 10.6-micrometer-wavelength lidar systems for observation of dense smoke aerosols and for determining specifications for procuring an optimum lidar system for this application. A 10.6-micrometer-wavelength CO2 mobile lidar system was constructed and interfaced to the data-processing electronics of the 0.7-micrometer-wavelength Mark IX mobile lidar system. The real-time minicomputer-based data system of the Mark IX lidar was programmed for intensity-modulated TV pictorial display of backscatter data collected from the two lidar systems on an alternate-firing basis. The two-lidar system participated in scheduled tests involving the generation of dense smoke aerosols. Data collected on smoke aerosols and also on road dust consisting of larger-sized particles show that while the 10.6-micrometer system is slightly more sensitive to road dust, it is very insensitive to smoke, and only very dense smokes can be observed.
