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 ...
Raman lidar for monitoring of aerosol pollution in the free troposphere
(Springer Nature, 2008)
Geometrical, optical, and microphysical properties of free-tropospheric pollution have been determined with multiwavelength Raman lidar at Leipzig, Germany. Long-term observations carried out at fixed times (three times ...
Cirrus optical properties observed with lidar, radiosonde, and satellite over the tropical Indian Ocean during the aerosol-polluted northeast and clean maritime southwest monsoon
(2007-09-14)
Cirrus formation and geometrical and optical properties of tropical cirrus as a function of height and temperature are studied on the basis of INDOEX ( Indian Ocean Experiment) lidar and radiosonde measurements and satellite ...
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 ...
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 ...
