Simultaneous tropospheric ozone monitoring using lidar and DOAS systems

摘要

Three remote-sensing systems for atmospheric trace species monitoring have been constructed in our group and have been simultaneously applied to monitor tropospheric ozone. An ozone differential absorption (DIAL) lidar based on a Raman shifted KrF excimer beam laser could be used for height profiling, and also for horizontal measurements after beam folding. This new system is described, including a presentation of measurements of Raman shifting efficiencies in hydrogen and deuterium. A Nd:YAG/dye laser based lidar system was used for horizontal and slant angle measurements. A differential optical absorption spectroscopy (DOAS) system, operated with high-pressure xenon lamps, was also used to measure the average concentration over a horizontal path. 11 refs, 6 figs, 1 tab (ERA citation 19:034264)
