    • Surface tension prevails over solute effect in organic-influenced cloud droplet activation 

      Ovadnevaite, Jurgita; Zuend, Andreas; Laaksonen, Ari; Sanchez, Kevin J.; Roberts, Greg; Ceburnis, Darius; Decesari, Stefano; Rinaldi, Matteo; Hodas, Natasha; Facchini, Maria Cristina; Seinfeld, John H.; O’ Dowd, Colin (Springer Nature, 2017-06-21)
      The spontaneous growth of cloud condensation nuclei (CCN) into cloud droplets under supersaturated water vapour conditions is described by classic Kohler theory(1,2). This spontaneous activation of CCN depends on the ...

    • The composition of nucleation and aitken modes particles during coastal nucleation events: evidence for marine secondary organic contribution 

      Vaattovaara, P.; Huttunen, P. E.; Yoon, Y. J.; Joutsensaari, J.; Lehtinen, K. E. J.; O'Dowd, C. D.; Laaksonen, A. (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 ...

    • Top-down and bottom-up aerosol–cloud closure: towards understanding sources of uncertainty in deriving cloud shortwave radiative flux 

      Sanchez, Kevin J.; Roberts, Gregory C.; Calmer, Radiance; Nicoll, Keri; Hashimshoni, Eyal; Rosenfeld, Daniel; Ovadnevaite, Jurgita; Preissler, Jana; Ceburnis, Darius; O'Dowd, Colin; Russell, Lynn M. (Copernicus GmbH, 2017-08-22)
      Top-down and bottom-up aerosol-cloud shortwave radiative flux closures were conducted at the Mace Head Atmospheric Research Station in Galway, Ireland, in August 2015. This study is part of the BACCHUS (Impact of Biogenic ...

    • Transport of boreal forest fire emissions from canada to europe 

      Forster, Caroline; Wandinger, Ulla; Wotawa, Gerhard; James, Paul; Mattis, Ina; Althausen, Dietrich; Simmonds, Peter; O'Doherty, S.; Jennings, S. Gerard; Kleefeld, Christoph; Schneider, Johannes; Trickl, Thomas; Kreipl, Stephan; Jäger, Horst; Stohl, Andreas (Wiley-Blackwell, 2001-10-01)
      In August 1998, severe forest fires occurred in many parts of Canada, especially in the Northwest Territories. In the week from August 5 to 11, more than 1000 different fires burned >1 x 10(6) ha of boreal forest, the ...

    • Wind-driven influences on aerosol light scattering in north-east atlantic air 

      Vaishya, Aditya; Jennings, S. Gerard; O'Dowd, Colin (Wiley-Blackwell, 2012-03-01)
      Ten years (2001-2010) of aerosol light-scattering measurements in N.E. Atlantic marine air are analysed to determine wind-speed related influences on scattering properties. The scattering coefficient and the backscattering ...
