    • Composition and properties of atmospheric particles in the eastern Atlantic and impacts on gas phase uptake rates 

      Allan, J. D.; Topping, D. O.; Good, N.; Irwin, M.; Flynn, M.; Williams, P. I.; Coe, H.; Baker, A. R.; Martino, M.; Niedermeier, N.; Wiedensohler, A.; Lehmann, S.; Mueller, K.; Herrmann, H.; McFiggans, G. (2009)
      Marine aerosol composition continues to represent a large source of uncertainty in the study of climate and atmospheric chemistry. In addition to their physical size and chemical composition, hygroscopicity plays a significant ...

    • 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, ...

    • Reactive Halogens in the Marine Boundary Layer (RHaMBLe) : the tropical North Atlantic experiments 

      Lee, J. D.; McFiggans, G.; Allan, J. D.; Baker, A. R.; Ball, S. M.; Benton, A. K.; Carpenter, L. J.; Commane, R.; Finley, B.

L.; Keene, W. C.; Lawler, M. J.; Lehmann, S.; Lewis, A. C.; Long, M. S.; Mahajan, A.; Methven, J.; Moller, S. J.; Mueller, K.; Mueller, T.; Niedermeier, N.; O'Doherty, S.; Oetjen, H.; Plane, J. M. C.; Pszenny, A. A. P.; Read, K. A.; Saiz-Lopez, A.; Saltzman, E. S.; Sander, R.; von Glasow, R.; Whalley, L.; Wiedensohler, A.; Young, D. (2010)
      The NERC UK SOLAS-funded Reactive Halogens in the Marine Boundary Layer (RHaMBLe) programme comprised three field experiments. This manuscript presents an overview of the measurements made within the two simultaneous remote ...

    • 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 ...
