    The effect of wind and plume height reconstruction methods on the accuracy of simple plume models — a second look at the 2010 Eyjafjallajökull eruption 
    Dürig, Tobias; Guðmundsson, Magnús T.; Ágústsdóttir, Thorbjörg; Högnadóttir, Thórdís; Schmidt, Louise (Springer, 2022-02-28)
    Real-time monitoring of volcanic ash plumes with the aim to estimate the mass eruption rate is crucial for predicting atmospheric ash concentration. Mass eruption rates are usually assessed by 0D and 1D plume models, which are fast and require only a ...

    Eruption dynamics of Anak Krakatau volcano (Indonesia) estimated using photogrammetric methods 
    Hochfeld, Isabell; Hort, Matthias; Schwalbe, Ellen; Dürig, Tobias (Springer, 2022-07-08)
    Analyzing video data from an uncrewed aerial vehicle (UAV) of two short-lived dome building events at Anak Krakatau volcano (Indonesia), we determine vertical and horizontal movements of the dome surface prior to explosions, as well as initial eruption ...

    Ground-Based Measurements of the 2014–2015 Holuhraun Volcanic Cloud (Iceland) 
    Pfeffer, Melissa; Bergsson, Baldur; Barsotti, Sara; Stefansdottir, Gerdur; Galle, Bo; Arellano, Santiago; Conde, Vladimir; Donovan, Amy; Ilyinskaya, Evgenia; Burton, Mike; Aiuppa, Alessandro; Whitty, Rachel; Simmons, Isla; Arason, Þórður; Jónasdóttir, Elín; Keller, Nicole; Yeo, Richard; Arngrímsson, Hermann; Jóhannsson, Þorsteinn; Butwin, Mary; Askew, Robert; Dumont, Stéphanie; von Löwis, Sibylle; Ingvarsson, Þorgils; La Spina, Alessandro; Thomas, Helen; Prata, Fred; Grassa, Fausto; Giudice, Gaetano; Stefansson, Andri; Marzano, Frank; Montopoli, Mario; Mereu, Luigi (MDPI AG, 2018-01-18)
    he 2014–2015 Bárðarbunga fissure eruption at Holuhraun in central Iceland was distinguished by the high emission of gases, in total 9.6 Mt SO2, with almost no tephra. This work collates all ground-based measurements of this extraordinary eruption cloud ...

    Quantifying the Effect of Wind on Volcanic Plumes: Implications for Plume Modeling 
    Dürig, Tobias; Guðmundsson, Magnús T.; Dioguardi, Fabio; Schmidt, Louise Steffensen (American Geophysical Union (AGU), 2023-01-13)
    The considerable effects that wind can have on estimates of mass eruption rates (MERs) in explosive eruptions based on volcanic plume height are well known but difficult to quantify rigorously. Many explicitly wind-affected plume models have the ...

    REFIR- A multi-parameter system for near real-time estimates of plume-height and mass eruption rate during explosive eruptions 
    Dürig, Tobias; Gudmundsson, Magnus Tumi; Dioguardi, Fabio; Woodhouse, Mark; Björnsson, Halldór; Barsotti, Sara; Witt, Tanja; Walter, Thomas R. (Elsevier BV, 2018-07)
    Meaningful forecasting of the atmospheric concentration and ground accumulation of volcanic ash during explo-sive eruptions requires detailed knowledge of the eruption source parameters. However, due to the large uncer-tainties in observations and ...
