Abstract

The layered-sphere volumetric backscatter coefficient is examined for possibly enhancing the estimates of the aerosol component distributions and their physical parameters with examples utilizing a coherent Lidar at 10.6 microns. It is found that at this wavelength alumina particles coated with soot, water, or sulfuric acid may exhibit greatly reduced backscattering due to destructive interference of the reflected waves plus guided wave action in the absorbing layer. Also, the layered-sphere calculations easily reduce to solid-sphere calculations as needed.
