  1. 14. Determining long-term volcanic gas emissions of SO$_2$ and BrO with DOAS

    Atmospheric Processes
    Poster

    Volcanic activity is usually connected to volcanic gas emissions. Observations of volcanic gas plumes could thus provide important information for studying the magmatic system and for risk assessment. Sulphur dioxide (SO$_2$), being directly emitted by volcanoes, and bromine monoxide (BrO), which is a secondary product from volcanic emissions of hydrogen bromine (HBr), are constituents of...

  2. 48. Evaluating a particle path of an eruption at Volcán de Colima

    Poster

    During its flight a volcanic particle experiences huge ranges of temperatures and chemical environments. To constrain the chemical and physical processes acting on this particle, we need to know its flight path.

    I studied 30 events measured by Doppler radar at Volcán de Colima, Mexico. From these I investigated the particle path of one event on 7th February 2015 at 15.15 UTC using...

  3. 38. High-Temperature Chemistry of Volcanic Gases in Air

    Atmospheric Processes
    Poster

    When volcanic gases enter the atmosphere, they encounter a drastically different chemical and physical environment, triggering a range of rapid processes including photochemistry, oxidation, and aerosol formation. These processes are critical to understanding the reactivity and evolution of volcanic emissions in the atmosphere yet are typically challenging to observe directly due to the nature...

  4. 41. The effect of pulsing of volcanic eruptions on eruption column height

    Atmospheric Processes
    Poster

    The correlation between the erupted mass and the height of volcanic eruption columns has been studied for quite some time. However, a recent study found, that the pulsing of an eruption also has an influence on column height and that certain types of pulsing behaviour can create higher eruption columns than non-pulsed eruptions even if the erupted mass is equal or even less. I am looking...
