Raman Augmentation for Rayleigh Lidar

Abstract : Raman detection has recently been added to the Air Force Geophysics Laboratory's ground based lidar system (GLEAM) to augment that system's Rayleigh lidar measurements. In this paper we examine the possibilities of using the Raman measurements to self-normalize, and downwardly extend our measurements of stratosphere and lower mesosphere molecular density. By combining inelastic (Raman) and elastic (Rayleigh plus Mie) scatter measurements, one can isolate the Mie component of the scattering using the techniques of Cooney and correct the data to eliminate the effects of atmospheric attenuation.
