Journal ArticleDOI
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.
Journal ArticleDOI
Measurement of atmospheric aerosol extinction profiles with a Raman lidar
TL;DR: 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.
Journal ArticleDOI
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.
Journal ArticleDOI
Two-mirror multipass absorption cell.
TL;DR: A multipass cell for absorption measurements with laser light is described, where the number of passes is adjusted by variation of the distance of two parallel concave mirrors.
Journal ArticleDOI

TL;DR: The Experimental Cloud Lidar Pilot Study (ECLIPS) was initiated to obtain statistics on cloud-base height, extinction, optical depth, cloud brokenness, and surface fluxes as mentioned in this paper.
