BVLOS UAS Operations in Highly-Turbulent Volcanic Plumes [PDF]

open access: yesFrontiers in Robotics and AI, 2020
Long-range, high-altitude Unoccupied Aerial System (UAS) operations now enable in-situ measurements of volcanic gas chemistry at globally-significant active volcanoes.

Advances in Bromine Speciation in Volcanic Plumes [PDF]

open access: yesFrontiers 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.

Atmospheric chemistry in volcanic plumes. [PDF]

open access: yesProc Natl Acad Sci U S A, 2010
Recent field observations have shown that the atmospheric plumes of quiescently degassing volcanoes are chemically very active, pointing to the role of chemical cycles involving halogen species and heterogeneous reactions on aerosol particles that have previously been unexplored for this type of volcanic plumes.

The vertical distribution of volcanic SO2 plumes measured by IASI [PDF]

open access: goldAtmospheric Chemistry and Physics, 2016
Sulfur dioxide (SO2) is an important atmospheric constituent that plays a crucial role in many atmospheric processes. Volcanic eruptions are a significant source of atmospheric SO2 and its effects and lifetime depend on the SO2 injection altitude ...

On the Fluctuations in Volcanic Plumes [PDF]

open access: hybridGeophysical Research Letters, 2020
AbstractSome basaltic open vent volcanoes show that spectroscopic SO2 measurements of a volcanic gas plume are characterized by a fluctuating signal. Understanding the origin of these fluctuations is of great interest for interpreting volcanic gas emission regimes. Although some fluctuations may be associated with intermittency in the source flux, some

Monitoring and forecasting Etna volcanic plumes [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2009
In this paper we describe the results of a project ongoing at the Istituto Nazionale di Geofisica e Vulcanologia (INGV). The objective is to develop and implement a system for monitoring and forecasting volcanic plumes of Etna.

Ash production by attrition in volcanic conduits and plumes [PDF]

open access: goldScientific Reports, 2017
Tephra deposits result from explosive volcanic eruption and serve as indirect probes into fragmentation processes operating in subsurface volcanic conduits.
