Atmospheric temperature measurement by a high spectral resolution lidar

Abstract

Following the suggestion of Young and Kattawar, we used the S6 model to recalculate Rayleigh-Brillouin spectra of nitrogen and the required measurement time for a high spectral resolution lidar (HSRL) which we proposed for atmospheric parameter measurements. As expected, the calculated sensitivity for atmospheric temperature using this model and a simpler SM model previously used is nearly the same. In this paper, the procedures for selecting the optimum temperature for an atomic vapor filter as well as for error analysis and sensitivity estimation were carried out. It is verified that the precision of atmospheric temperature measurement with a HSRL system under construction is feasible for practical use.
