dc.description.abstractA new lidar instrument has been developed to measure tropospheric ozone and water vapor at low altitude. The lidar uses Raman scattering of an UV beam from atmospheric nitrogen, oxygen, and water vapor to retrieve ozone and water-vapor vertical profiles. By numerical simulation we investigate the sensitivity of the method to both atmospheric and device perturbations. The aerosol optical effect in the planetary boundary layer, ozone interference in water-vapor retrieval, statistical error, optical cross talk between Raman-shifted channels, and optical cross talk between an elastically backscattered signal in Raman-shifted signals and an afterpulse effect are studied in detail. In support of the main conclusions of this model study, time series of ozone and water vapor obtained at the Swiss Federal Institute of Technology in Lausanne and during a field campaign in Crete are presented. They are compared with point monitor and balloon sounding measurements for daytime and nighttime conditions.
dc.description.sponsorshipThis study was supported by the Swiss National Science Foundation under contract 21-50861.97 and the Swiss Federal Office for Science and Education under contract 97.0377. The balloon sounding was provided by NASA’s ~Total Ozone Mapping Spectrometer ~TOMS! project. The authors thank the organizers of the PAUR II project for logistical support in Crete and are grateful to Ed Browell and his team at NASA Langley for stimulating discussions.
