    • The EMEP Intensive Measurement Period campaign, 2008-2009: characterizing carbonaceous aerosol at nine rural sites in Europe 

      Yttri, Karl Espen; Simpson, David; Bergström, Robert; Kiss, Gyula; Szidat, Sonke; Ceburnis, Darius; Eckhardt, Sabine; Hueglin, Christoph; Nojgaard, Jacob Kleno; Perrino, Cinzia; Pisso, Ignazio; Prevot, Andre Stephan Henry; Putaud, Jean-Philippe; Spindler, Gerald; Vana, Milan; Zhang, Yan-Lin; Aas, Wenche (European Geosciences Union (EGU), 2019-04-03)
      Carbonaceous aerosol (total carbon, TCp) was source apportioned at nine European rural background sites, as part of the European Measurement and Evaluation Programme (EMEP) Intensive Measurement Periods in fall 2008 and ...

    • Sea-spray regulates sulfate cloud droplet activation over oceans 

      Fossum, Kirsten N.; Ovadnevaite, Jurgita; Ceburnis, Darius; Preißler, Jana; Snider, Jefferson R.; Huang, Ru-Jin; Zuend, Andreas; O’Dowd, Colin (Nature Research (part of Springer Nature), 2020-04-08)
      Sulfate aerosols are typically the dominant source of cloud condensation nuclei (CCN) over remote oceans and their abundance is thought to be the dominating factor in determining oceanic cloud brightness. Their activation ...

    • Sophisticated clean air strategies required to mitigate against particulate organic pollution 

      Grigas, Tomas; Ovadnevaite, Jurgita; Ceburnis, Darius; Moran, E.; McGovern, F.M.; Jennings, Stephen G.; O'Dowd, Colin (Nature Publishing Group, 2017-03-17)
      Since the 1980's, measures mitigating the impact of transboundary air pollution have been implemented successfully as evidenced in the 1980-2014 record of atmospheric sulphur pollution over the NE-Atlantic, a key region ...

    • Summertime primary and secondary contributions to Southern Ocean cloud condensation nuclei 

      Fossum, Kirsten N.; Ovadnevaite, Jurgita; Ceburnis, Darius; Dall'Osto, Manuel; Marullo, Salvatore; Bellacicco, Marco; Simó, Rafel; Liu, Dantong; Flynn, Michael; Zuend, Andreas; O'Dowd, Colin (Nature Research (part of Springer Nature), 2019-07-18)
      Atmospheric aerosols in clean remote oceanic regions contribute significantly to the global albedo through the formation of haze and cloud layers; however, the relative importance of ‘primary’ wind-produced sea-spray over ...

    • 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. (European Geosciences Union (EGU), 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 ...

    • Volcanic sulphate and arctic dust plumes over the North Atlantic Ocean 

      Ovadnevaite, Jurgita; Ceburnis, Darius; Dupuy, Regis; Berresheim, Harald; O Dowd, Colin D. (Elsevier, 2009)
      High time resolution aerosol mass spectrometry measurements were conducted during a field campaign at Mace Head Research Station, Ireland, in June 2007. Observations on one particular day of the campaign clearly indicated ...
