Abstract
Ozone measurements using the LAMP (Laser Atmospheric Measurement Program) and LAPS (Laser Atmosphere Profiling System) lidars have been characterized and will be presented in this thesis. The LIDAR (Light Detector And Ranger) systems were developed to measure molecular density, atmospheric temperature and atmospheric concentrations of water vapor. The ozone (03) measurement capability was added to correct the daytime water vapor measurement by removing the absorption effect of tropospheric ozone. These signals are now used to characterize ozone in the lower atmosphere. The Raman DIAL technique provides range-resolved measurements of ozone in the atmosphere up to an altitude of 3 km. The accuracy and robustness has been increased over traditional measurement techniques. The Raman DIAL error is mainly associated with statistical error from the returned photon count. The typical smallest error, about 4 ppb, is measured near l km with a 75 m resolution and a 60 minute integration.
