Evolution of the ice phase in tropical altocumulus : SAMUM lidar observations over Cape Verde
(2009-09-16)
The formation of the ice phase in tropical altocumulus has been studied with multiwavelength aerosol-cloud Raman lidar, wind Doppler lidar, and radiosonde, providing information on geometrical and optical properties, cloud ...
Ten years of multiwavelength Raman lidar observations of free-tropospheric aerosol layers over central Europe : Geometrical properties and annual cycle
(2008-10-27)
We present geometrical properties and seasonal variations of appearance of aerosol particle pollution in the free troposphere over the central European lidar site at Leipzig, Germany. The data set has been acquired with ...
Aerosol-type-dependent lidar ratios observed with Raman lidar
(2007-08-17)
[1] We summarize our Raman lidar observations which were carried out in Europe, Asia, and Africa during the past 10 years, with focus on particle extinction-to-backscatter ratios ( lidar ratios) and (A) over circle ngstrom ...
Multiwavelength Raman lidar observations of particle growth during long-range transport of forest-fire smoke in the free troposphere
(2007-03-02)
We present particle effective radii and Angstrom exponents of aged free-tropospheric forest-fire smoke. The particle plumes were observed with different multiwavelength Raman lidars downwind of the fires that burned in ...
Characterization of atmospheric aerosols with multiwavelength Raman lidar
(SPIE, 2007)
Multiwavelength Raman lidar observations have matured into a powerful tool for the vertical resolved characterization of optical and microphysical properties of atmospheric aerosol particles. Raman lidars that operate with ...
Raman lidar observations of aged Siberian and Canadian forest fire smoke in the free troposphere over Germany in 2003 : Microphysical particle characterization
(2005-09-02)
Dual-wavelength Raman lidar observations were regularly carried out at Leipzig (51.3 degrees N, 12.4 degrees E) from May to August 2003. The measurements showed that particle backscatter and extinction coefficients in the ...
Daytime operation of a pure rotational Raman lidar by use of a Fabry-Perot interferometer
(2005-06-10)
We propose to use a Fabry-Perot interferometer (FPI) in a pure rotational Raman lidar to isolate return signals that are due to pure rotational Raman scattering from atmospheric nitrogen against the sky background. The ...
Ice formation in Saharan dust over central Europe observed with temperature/humidity//aerosol Raman lidar
(2005-04-26)
[1] Three gravity-wave-induced clouds and a glaciating altocumulus layer were continuously monitored with lidar at Leipzig, Germany, on 21 November 2003. The midtropospheric clouds formed in Saharan dust at heights from ...
Multiyear aerosol observations with dual-wavelength Raman lidar in the framework of EARLINET
(2004-07-10)
For the first time, a Raman lidar operating simultaneously in the ultraviolet (UV) and in the visible wavelength range was employed to measure vertical profiles of volume extinction coefficients of particles at 355 and 532 ...
Closure study on optical and microphysical properties of a mixed urban and Arctic haze air mass observed with Raman lidar and Sun photometer
(2004-07)
[1] We present a comprehensive optical and microphysical characterization of an intense haze event observed over Leipzig ( 51.3 degreesN, 12.4 degreesE), Germany, in April 2002. This event was characterized by unusually ...
