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, ... -
Relative humidity dependence of aerosol optical properties and direct radiative forcing in the surface boundary layer at Xinken in Pearl River Delta of China : An observation based numerical study
Cheng, Y. F.; Wiedensohler, A.; Eichler, H.; Heintzenberg, J.; Tesche, Matthias; Ansmann, A.; Wendisch, M.; Su, H.; Althausen, D.; Herrmann, H.; Gnauk, T.; Brüggemann, E.; Hu, M.; Zhang, Y. H. (2008-08)In a numerical study, influences of relative humidity (RH) on aerosol optical properties and direct radiative forcing in the surface boundary layer at Xinken (XK) in Pearl River Delta of China are investigated based on the ... -
Strong particle light absorption over the Pearl River Delta (south China) and Beijing (north China) determined from combined Raman lidar and Sun photometer observations
Mueller, D.; Tesche, Matthias; Eichler, H.; Engelmann, R.; Althausen, D.; Ansmann, A.; Cheng, Y. F.; Zhang, Y. H.; Hu, M. (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) ...
