By: T. M. Vanreken; M. Wen; C. L. Faiola

Description: Laboratory for Atmospheric Research, Department of Civil and Environmental Engineering, Washington State University, Pullman, Washington, USA. The largest global source of secondary organic aerosol (SOA) in the atmosphere is derived from the oxidation of biogenic emissions. Plant stressors associated with a changing environment can alter both the quantity and composition of the compounds that are emitted. Alterations to the biogenic volatile organic compo...

By: M. Rex; I. Wohltmann

Description: Alfred Wegener Institute for Polar and Marine Research, Potsdam, Germany. Stratospheric vertical winds from analysis data in pressure (p) or hybrid pressure (σ-p) coordinates, for use in e.g. chemical transport models (CTMs) or trajectory models, often suffer both from excessive noise and errors in their mean magnitude, which in turn can introduce errors in important dynamical quantities like vertical mixing or constituent transport with...

Description: Department of Chemistry, Inha University, Incheon, 402-751, Korea. Haze is an atmospheric phenomenon that leads to low visibility, and is mostly due to elevated levels of fine particulate matter. It can have effects on cloud formation, public health, agriculture, and even the global climate. Although urban haze has been increasing in occurrence over the past several years over the Seoul-Incheon metropolis, Korea, studies of the morphology and chemical c...
