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 ...
Vertically resolved separation of dust and smoke over Cape Verde using multiwavelength Raman and polarization lidars during Saharan Mineral Dust Experiment 2008
(2009-07-08)
Multiwavelength aerosol Raman lidar in combination with polarization lidar at Praia (14.9 degrees N, 23.5 degrees W), Cape Verde, is used to separate the optical properties of desert dust and biomass burning particles as ...
EARLINET observations of the 14-22-May long-range dust transport event during SAMUM 2006 : validation of results from dust transport modelling
(2009-02)
We observed a long-range transport event of mineral dust from North Africa to South Europe during the Saharan Mineral Dust Experiment (SAMUM) 2006. Geometrical and optical properties of that dust plume were determined with ...
Radiative and dynamic effects of absorbing aerosol particles over the Pearl River Delta, China
(2008-08)
Results are reported from a ground-based measurement campaign conducted in a highly polluted region in southeast of China in October-November 2004. The experiment focused on absorbing aerosol particles and their effects ...
Influence of Saharan dust on cloud glaciation in southern Morocco during the Saharan Mineral Dust Experiment
(2008-02-27)
Multiwavelength lidar, Sun photometer, and radiosonde observations were conducted at Ouarzazate ( 30.9 degrees N, 6.9 degrees W, 1133 m above sea level, asl), Morocco, in the framework of the Saharan Mineral Dust Experiment ...
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 ...
Strong particle light absorption over the Pearl River Delta (south China) and Beijing (north China) determined from combined Raman lidar and Sun photometer observations
(2006-10-24)
[1] Particle size and absorption properties have been determined from combined one-wavelength Raman lidar and Sun photometer measurements in the Pearl River Delta (South China) in October 2004, and in Beijing (North China) ...
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 ...
