Optical and microphysical characterization of biomass-burning and industrial-pollution aerosols from multiwavelength lidar and aircraft measurements
(2002-11-16)
[1] During the Lindenberg Aerosol Characterization Experiment (LACE 98) simultaneous measurements with ground-based and airborne lidars and with two aircraft equipped with aerosol in situ instrumentation were performed. ...
Airborne observations of dry particle absorption and scattering properties over the northern Indian Ocean
(2002-11)
[1] Airborne measurements of the absorption and scattering coefficients of dry aerosols, at 525 and 545 nm, respectively, were performed over the northern Indian Ocean during the Indian Ocean Experiment (INDOEX). In the ...
Relative-humidity profiling in the troposphere with a Raman lidar
(2002-10-20)
We describe a Raman-lidar-based approach to acquiring profiles of the relative humidity of air. For this purpose we combined in one instrument the Raman-lidar techniques that are used for the profiling of water vapor and ...
European pollution outbreaks during ACE 2 : Microphysical particle properties and single-scattering albedo inferred from multiwavelength lidar observations
(2002-08-06)
We present vertically resolved physical particle properties and the single-scattering albedo at 532 nm of pollution plumes advected from the European continent out over the Atlantic Ocean. The parameters follow from the ...
European pollution outbreaks during ACE 2 : Optical particle properties inferred from multiwavelength lidar and star-Sun photometry
(2002-08)
[1] On the basis of multiwavelength backscatter and 532-nm extinction profiling with lidar at Sagres (37degreesN, 9degreesW), southern Portugal, and optical depth observations with a star photometer at the lidar site and ...
Tropospheric aerosol layers after a cold front passage in January 2000 as observed at several stations of the German Lidar Network
(2002-07)
Using the German Lidar Network, we analysed 2 years of lidar observations of aerosol layers. Here we report in particular on a cold front event in January 2000 with Rayleigh/Mie/Raman lidar measurements taken both in the ...
Inversion with regularization for the retrieval of tropospheric aerosol parameters from multiwavelength lidar sounding
(2002-06-20)
We present an inversion algorithm for the retrieval of particle size distribution parameters, i.e., mean (effective) radius, number, surface area, and volume concentration, and complex refractive index from multiwavelength ...
Dual-wavelength Raman lidar observations of the extinction-to-backscatter ratio of Saharan dust
(2002-05-01)
[1] For the first time, height profiles of the extinction-to-backscatter ratio (lidar ratio) of desert dust particles were simultaneously measured at 355 and 532 nm. The observations were performed with an advanced Raman ...
An intercomparison of aerosol light extinction and 180 degrees backscatter as derived using in situ instruments and Raman lidar during the INDOEX field campaign
(2002)
[1] Aircraft in situ and Raman lidar profiles of aerosol light extinction (sigma(ep)) and 180degrees backscattering (beta(p)) are compared for 6 days during the Indian Ocean Experiment (INDOEX). The measurements of sigma(ep) ...
