High spectral resolution lidar using spherical Fabry-Perot to measure aerosol and atmospheric molecular density

Abstract : In theory, the HSRL method should expand the domain of validity of the atmospheric molecular density and temperature profiles of the Rayleigh LIDAR. This, in the UTLS under 30 km with the accuracy of 1 K, while suppressing the particulate contribution. We tested a Spherical Fabry-Perot which achieves these performances while keeping a big flexibility in optical alignment. Performances and limitations of this device will be shown.
