Arctic haze over Central Europe
Heintzenberg, J.; Tuch, T.; Wehner, B.; Wiedensohler, A.; Wex, H.; Ansmann, A.; Mattis, I.; Mueller, D.; Wendisch, M.; Eckhardt, S.; Stohl, A. (2003-07)An extraordinary aerosol situation over Leipzig, Germany in April 2002 was investigated with a comprehensive set of ground-based volumetric and columnar aerosol data, combined with aerosol profiles from lidar, meteorological ... -
Hygroscopic properties and extinction of aerosol particles at ambient relative humidity in South-Eastern China
Eichler, H.; Cheng, Y. F.; Birmili, W.; Nowak, A.; Wiedensohler, A.; Brüggemann, E.; Gnauk, T.; Herrmann, H.; Althausen, D.; Ansmann, A.; Engelmann, R.; Tesche, Matthias; Wendisch, M.; Zhang, Y. H.; Hu, M.; Liu, S.; Zeng, L. M. (2008-08)During the "Program of Regional Integrated Experiments of Air Quality over Pearl River Delta 2004 (PRIDE-PRD2004)" hygroscopic properties of particles in the diameter range 22 nm to 10 μ m were determined. For that purpose, ... -
Measurements of desert dust optical characteristics at Porte au Sahara during SAMUM
Von Hoyningen-Huene, W.; Dinter, T.; Kokhanovsky, A. A.; Burrows, J. P.; Wendisch, M.; Bierwirth, E.; Mueller, D.; Diouri, M. (2009-02)Main optical characteristics of desert dust, such as phase function and single scattering albedo, have been derived from combinations of sun-/sky-radiometer and satellite measurements during the SAMUM experiment (10 May-10 ... -
Microphysical particle parameters from extinction and backscatter lidar data by inversion with regularization : experiment
Mueller, D.; Wagner, F.; Wandinger, U.; Ansmann, A.; Wendisch, M.; Althausen, D.; von Hoyningen-Huene, W. (2000-04-20)We present effective radius, volume, surface-area, and number concentrations as well as mean complex refractive index of tropospheric particle size distributions based on lidar measurements at six wavelengths. The parameters ... -
Optical and microphysical characterization of biomass-burning and industrial-pollution aerosols from multiwavelength lidar and aircraft measurements
Wandinger, U.; Mueller, D.; Boeckmann, C.; Althausen, D.; Matthias, M.; Bosenberg, J.; Weiss, A.; Fiebig, M.; Wendisch, M.; Stohl, A.; Ansmann, A. (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. ... -
Radiative and dynamic effects of absorbing aerosol particles over the Pearl River Delta, China
Wendisch, M.; Hellmuth, O.; Ansmann, A.; Heintzenberg, J.; Engelmann, R.; Althausen, D.; Eichler, H.; Mueller, D.; Hu, M.; Zhang, Y.; Mao, J. (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 ... -
