Journal ArticleDOI
Investigation of nucleation events vertical extent: a long term study at two different altitude sites
J. Boulon,Karine Sellegri,Maxime Hervo,David Picard,Jean-Marc Pichon,Patrick Fréville,Paolo Laj +6 more
TL;DR: Hovewer et al. as discussed by the authors presented an analysis of the occurrence of nucleation events during more than three years of measurements at two different rural altitude sites, the puy de Dome research station (1465 m a.s.l.) and the Opme station (660 m a sl.), central France.

TL;DR: In this article, the decay phase of an unprecedented, record-breaking stratospheric perturbation caused by wildfire smoke is reported and discussed in terms of geometrical, optical, and microphysical aerosol properties.
Journal ArticleDOI
Physical and optical properties of 2010 Eyjafjallajökull volcanic eruption aerosol: ground-based, Lidar and airborne measurements in France
Maxime Hervo,Boris Quennehen,Nina Iren Kristiansen,J. Boulon,Andreas Stohl,Patrick Fréville,Jean-Marc Pichon,David Picard,Philippe Labazuy,Mathieu Gouhier,Jean-Claude Roger,Aurélie Colomb,Alfons Schwarzenboeck,Karine Sellegri +13 more
TL;DR: In this article, a combination of in situ optical and physical characterization of the volcanic ash allowed the calculation of the mass-to-extinction ratio (η) with no assumptions on the aerosol density.
Journal ArticleDOI
Near-source Doppler radar monitoring of tephra plumes at Etna
Franck Donnadieu,Patrick Fréville,Claude Hervier,Mauro Coltelli,Simona Scollo,Michele Prestifilippo,Sébastien Valade,S. Rivet,P. Cacault +8 more
TL;DR: The VOLDORAD 2B radar system as discussed by the authors is integrated into a volcano instrumental network dedicated to the continuous near-source monitoring of tephra emissions from Etna's summit craters.
Journal ArticleDOI
