    • Ash and fine-mode particle mass profiles from EARLINET-AERONET observations over central Europe after the eruptions of the Eyjafjallajökull volcano in 2010 

      Ansmann, A.; Tesche, Matthias; Seifert, P.; Gross, Silke; Freudenthaler, V.; Apituley, A.; Wilson, K. M.; Serikov, I.; Linné, H.; Heinold, B.; Hiebsch, A.; Schnell, F.; Schmidt, J.; Mattis, I.; Wandinger, U.; Wiegner, M. (2011-01-01)
      A combined lidar-photometer method that permits the retrieval of vertical profiles of ash and non-ash (fine-mode) particle mass concentrations is presented. By using a polarization lidar, the contributions of non-ash and ...

    • Four-dimensional distribution of the 2010 Eyjafjallajökull volcanic cloud over Europe observed by EARLINET 

      Pappalardo, G.; Mona, L.; D'Amico, G.; Wandinger, U.; Adam, M.; Amodeo, A.; Ansmann, A.; Apituley, A.; Alados Arboledas, L.; Balis, D.; Boselli, A.; Bravo-Aranda, J. A.; Chaikovsky, A.; Comeron, A.; Cuesta, J.; De Tomasi, F.; Freudenthaler, V.; Gausa, M.; Giannakaki, E.; Giehl, H.; Giunta, A.; Grigorov, I.; Groß, S.; Haeffelin, M.; Hiebsch, A.; Iarlori, M.; Lange, D.; Linné, H.; Madonna, F.; Mattis, I.; Mamouri, R.

A.; Schmidt, J.; Schnell, F.; Seifert, P.; Serikov, I.; Sicard, M.; Simeonov, V.; Spinelli, N.; Stebel, K.; Tesche, Matthias; Trickl, T.; Wang, X.; Wagner, F.; Wiegner, M.; Wilson, K. M. (2013-04-29)
      The eruption of the Icelandic volcano Eyjafjallaj ökull in April-May 2010 represents a "natural experiment" to study the impact of volcanic emissions on a continental scale. For the first time, quantitative data about the ...

    • Ice formation in ash-influenced clouds after the eruption of the Eyjafjallajkull volcano in April 2010 

      Seifert, P.; Ansmann, A.; Gross, Silke; Freudenthaler, V.; Heinold, B.; Hiebsch, A.; Mattis, I.; Schmidt, J.; Schnell, F.; Tesche, Matthias; Wandinger, U.; Wiegner, M. (2011-10-27)
      The influence of volcanic ash on heterogeneous ice nucleation in tropospheric clouds is investigated on the basis of 90 observed cloud cases. The clouds were observed with polarization lidars at the two central-European ...
