Abstract
A basic lidar system performs the expected function of light detection and ranging via simultaneous Rayleigh scattering from atmospheric (air) molecules and Mie scattering from suspended aerosol particles, including water droplets and ice crystals. As such, the spatial distribution of scattering centers may be qualitatively displayed. However, no atmospheric parameters can be measured directly since the backscattered light from air molecules and aerosol particles is not separated spectroscopically. Useful information such as aerosol backscattering profile can be obtained from a basic lidar system only if assumptions such as air molecular density based on modeling or other measurements are made. In doing so, a large number of uncertainties are introduced. A more direct method is clearly needed.
