Abstract

We present a new method of the rotational Raman lidar using an absorption cell of metallic vapor. The conventional rotational Raman lidar can hardly measure the temperature profiles in the atmosphere containing a lot of aerosol particles like in the lower troposphere. In this paper, it is shown by the computer simulation that the aerosol scattering contamination disturbing the measurement can be easily eliminated by using a metallic vapor filter in addition to the interference filters. Moreover, the interference filters of which the characteristics affect decisively the measurement accuracy can be designed more suitably. We design and fabricate the lidar system with a Na vapor cell and a narrowband dye laser to prove the usefulness of this method experimentally.
