Description:
How stratospheric are deep stratospheric intrusions? LUAMI 2008 Thomas Trickl, Hannes Vogelmann, Andreas Fix, Andreas Schäfler, Martin Wirth, Bertrand Calpini, Gilbert Levrat, Gonzague Romanens, Arnoud Apituley, Keith M. Wilson, Robert Begbie, Jens Reichardt, Holger Vömel, and Michael Sprenger Atmos. Chem. Phys., 16, 8791-8815, doi:10.5194/acp-16-8791-2016, 2016 A rather homogeneous deep stratospheric intrusion event was mapped by vertical sounding over central Europe and by model calculations along the transport path. The very low minimum H 2 O mixing ratios demonstrate almost negligible mixing with tropospheric air during the downward transport. The vertical distributions of O 3 and aerosol were transferred from the source region to Europe without major change. A rather shallow outflow from the stratosphere was found.
