Abstract
Several laser remote sensing techniques are used to characterize the properties of aerosols. The various techniques include: backscatter, optical extinction using Raman scatter, and bistatic/multistatic scattering using the polarization ratio of the scattering phase function. The number density, size, and size distribution are obtained under the assumption of spherical scatterers. Other measurements can be used to describe additional properties, such as aerosol type based upon approximate refractive index and detected departure from spherical, when simultaneous measurements at several wavelengths and several angles are analyzed. Examples are shown to demonstrate our present capability to characterize aerosol particles using recently developed techniques.
