Abstract

For the purpose of low tropospheric ozone and water vapor lidar measurements, a recent method, avoiding the high sensitivity to the inhomogeneous aerosols of the elastic DIAL, is offered by the Raman shifts of a single pump beam in the UV. In this work, we investigate the sensitivity of the method to both atmospheric and device perturbations by numerical simulation. The following effects have been modelled: inhomogeneous aerosol load, statistical error, deterioration due to cross-talk between the N₂ & O₂ Raman-shifted channels, deterioration due to intrusion of the elastically backscattered signal in the Raman-shifted signals, after-pulse noise.
