Increased respiratory morbidity associated with exposure to a mature volcanic plume from a large Icelandic fissure eruption. [PDF]
Nat Commun, 2021 The 2014–15 Holuhraun eruption in Iceland was the largest fissure eruption in over 200 years, emitting prodigious amounts of gas and particulate matter into the troposphere.

Multi-Sensor Analysis of a Weak and Long-Lasting Volcanic Plume Emission
Remote Sensing, 2020 Volcanic emissions are a well-known hazard that can have serious impacts on local populations and aviation operations. Whereas several remote sensing observations detect high-intensity explosive eruptions, few studies focus on low intensity and long ...

In situ and space-based observations of the Kelud volcanic plume: The persistence of ash in the lower stratosphere. [PDF]
J Geophys Res Atmos, 2016 Volcanic eruptions are important causes of natural variability in the climate system at all time scales. Assessments of the climate impact of volcanic eruptions by climate models almost universally assume that sulfate aerosol is the only radiatively ...

Advances in Bromine Speciation in Volcanic Plumes [PDF]
Frontiers in Earth Science, 2018 Volcanoes are a significant halogen source to the atmosphere. After water, carbon dioxide and sulfur compounds, halogens are often the most abundant gases in volcanic plumes. In the past, less attention was given to the heavy halogens bromine and iodine.

Volcanic Plume CO2 Flux Measurements at Mount Etna by Mobile Differential Absorption Lidar
Geosciences, 2017 Volcanic eruptions are often preceded by precursory increases in the volcanic carbon dioxide (CO2) flux. Unfortunately, the traditional techniques used to measure volcanic CO2 require near-vent, in situ plume measurements that are potentially hazardous ...

Reactive bromine chemistry in Mount Etna's volcanic plume: the influence of total Br, high-temperature processing, aerosol loading and plume–air mixing [PDF]
Atmospheric Chemistry and Physics, 2014 Volcanic emissions present a source of reactive halogens to the troposphere, through rapid plume chemistry that converts the emitted HBr to more reactive forms such as BrO.

Turbulence and particle dynamics in volcanic clouds in humid atmospheres [PDF]
Scientific ReportsThe eruption of Hunga Tonga–Hunga Ha’apai (HTHH), which began around 04:00 UTC on January 15, 2022, injected substantial amounts of water vapor above the stratosphere. The subsequent explosions occurred in an exceptionally humid environment. Although the

New particle formation in the volcanic eruption plume of the Piton de la Fournaise: specific features from a long-term dataset [PDF]
Atmospheric Chemistry and Physics, 2019 New particle formation (NPF) is a key atmospheric process which may be responsible for a major fraction of the total aerosol number burden at the global scale, including in particular cloud condensation nuclei (CCN).
