Abstract
A combined Raman elastic-backscatter lidar for tropospheric profiling of moisture, ozone, and aerosols and stratospheric profiling of ozone, aerosols, and temperature is presented. A XeCl excimer and a frequency-tripled Nd:YAG laser serve as light sources. An eight-channel interference-filter polychromator is used as the receiver. Water vapor, particle extinction and backscatter coefficients, and the particle lidar ratio are determined by the use of the Raman-lidar technique. For depolarization studies the parallel- and cross-polarized components of the 355-nm elastic-backscatter signal are detected. Ozone can be derived from the Raman nitrogen channels as well as from the elastic-backscatter channels by applying the Raman-DIAL and the DIAL technique, respectively. The temperature is obtained from the Raman and Rayleigh signals in the particle-free stratosphere. The apparatus is described in detail. Measurement examples showing the capabilities of the new system are given.
