Aerosol formation during parforce: ternary nucleation of h2so4, nh3, and h2o
(Wiley-Blackwell, 2002-01-01)A new version of a ternary nucleation (sulphuric acid-ammonia-water) model based on classical nucleation theory, but with an improved ability to predict nucleation rates over a larger temperature range (258-303 K) compared ... -
Iodine dioxide nucleation simulations in coastal and remote marine environments
(Wiley-Blackwell, 2009-01-27)Aerosol dynamical box model simulations of coastal new particle formation were performed in order to investigate the nucleation and growth mechanisms in this environment. In the simulations the nucleating vapor was assumed ... -
Observations of high concentrations of i2and io in coastal air supporting iodine-oxide driven coastal new particle formation
(Wiley-Blackwell, 2010-02-01)Theoretical studies have predicted that concentrations of gaseous I-2 and IO of the order of 80-100 ppt and 4050 ppt, respectively, are required in coastal air to account for photochemically-driven coastal new-particle ... -
Statistical characteristics and predictability of particle formation events at mace head
(Wiley-Blackwell, 2006-01-01)[ 1] The seasonal characteristics of coastal nucleation events at the Mace Head Atmospheric Research Station, resulting from exposure of macroalgae to the atmosphere, were analyzed for a 2-year period from August 2002 to ... -
The composition of nucleation and aitken modes particles during coastal nucleation events: evidence for marine secondary organic contribution
(Copernicus GmbH, 2006-10-12)Newly-formed nanometer-sized particles have been observed at coastal and marine environments world wide. Organic species have so far not been detected in those newly-formed nucleation mode particles. In this study, we ... -
The spatial distribution of the reactive iodine species io from simultaneous active and passive doas observations
(Copernicus GmbH, 2010-03-01)We present investigations of the reactive iodine species (RIS) IO, OIO and I-2 in a coastal region from a field campaign simultaneously employing active long path differential optical absorption spectroscopy (LP-DOAS) as ...
