Determination of time- and height-resolved volcanic ash emissions and their use for quantitative ash dispersion modeling: the 2010 Eyjafjallajökull eruption
Andreas Stohl,A. J. Prata,Sabine Eckhardt,Lieven Clarisse,Adam J. Durant,Adam J. Durant,Adam J. Durant,Stephan Henne,Nina Iren Kristiansen,Andreas Minikin,Ulrich Schumann,Petra Seibert,Kerstin Stebel,Helen Thomas,Thorsteinn Thorsteinsson,Kjetil Tørseth,Bernadett Weinzierl +16 more
TL;DR: In this article, an inversion scheme was used to estimate the volcanic ash source strength as a function of altitude and time, and the results showed that volcanic ash concentrations at some altitude in the atmosphere exceeded the limits for the "Normal" flying zone in up to 14 % (6-16 %), 2 % (1-3 %) and 7 % (4-11 %) of the European area.

Burkhart,Anne Fouilloux,Jerome Brioude,Anne Philipp,Petra Seibert,Andreas Stohl +21 more
TL;DR: The Lagrangian particle dispersion model FLEXPART as mentioned in this paper was designed for calculating the long-range and mesoscale dispersion of hazardous substances from point sources, such as those released after an accident in a nuclear power plant.

Sparks,Susan C. Loughlin,Matthew C. Hort,Susan Leadbetter,B. J. Devenish,Alistair J. Manning,Claire Witham,Jim Haywood,Brian Golding +19 more
TL;DR: In this article, the authors described the ash concentration forecasting method, its rationale and how it evolved over time in response to new information and user requirements, and compared the predicted peak ash concentrations with observations obtained by ground-based and research aircraft instrumentation.
Journal ArticleDOI
Remote sensing and inverse transport modeling of the Kasatochi eruption sulfur dioxide cloud
Nina Iren Kristiansen,Andreas Stohl,Alfred J Prata,Andreas Richter,Sabine Eckhardt,Petra Seibert,Anja Hoffmann,Christoph Ritter,L. Bitar,Thomas J. Duck,Kerstin Stebel +10 more
TL;DR: In this article, an analytical inversion method is used to estimate the vertical profile of sulfur dioxide (SO2) emissions from the major 2008 eruption of Kasatochi Volcano, located on the Aleutian Arc, Alaska.
