Measurement of atmospheric aerosol extinction profiles with a Raman lidar
TLDR
A method is presented that permits the determination of atmospheric aerosol extinction profiles from measured Raman lidar signals, no critical input parameters are needed, which could cause large uncertainties of the solution.Abstract:
A method is presented that permits the determination of atmospheric aerosol extinction profiles from measured Raman lidar signals. No critical input parameters are needed, which could cause large uncertainties of the solution, as is the case in the Klett method for the inversion of elastic lidar returns.read more

Independent measurement of extinction and backscatter profiles in cirrus clouds by using a combined Raman elastic-backscatter lidar
TL;DR: Examples covering the measured range of extinction-to-backscatter ratios (lidar ratios) in ice clouds are presented and simple backscatter lidars can provide reliable information about the cloud optical depth and the mean cloud lidar ratio.

Combined raman elastic-backscatter LIDAR for vertical profiling of moisture, aerosol extinction, backscatter, and LIDAR ratio
Albert Ansmann,Maren Riebesell,Ulla Wandinger,Claus Weitkamp,E. Voss,W. Lahmann,Walfried Michaelis +6 more
TL;DR: In this paper, a combined Raman elastic-backscatter lidar has been developed, where a XeCl excimer laser is used as the radiation source and inelastic Raman backscatter signals are spectrally separated from the elastic signal with a filter or grating polychromator.

Analysis of atmospheric lidar observations: some comments
TL;DR: A restatement of the more general solution of Fernald et al.l which is also applicable to mildly turbid atmospheres where both aerosol and molecular scatterers must be considered in the analysis.

Stable analytical inversion solution for processing lidar returns
TL;DR: A simple analytical method is presented that shows some potential for application to the problem of extracting attenuation and backscatter coefficients in an inhomogeneous atmosphere from the return signal of a monostatic single-wavelength lidar system.

Absorption Coefficients of Ozone in the Ultraviolet and Visible Regions
TL;DR: In this article, the absorption coefficients of ozone have been measured in the ultraviolet and visible regions using essentially 100% pure ozone, and the results confirm those of Inn and Tanaka in ultraviolet, and those of Vigroux in the visible region.
