Halogen activation in the plume of Masaya volcano: field observations and box model investigations
(Atmospheric Chemistry and Physics, 2020)
Volcanic emissions are a source of halogens to the atmosphere. Rapid reactions convert the initially emitted hydrogen halides (HCl, HBr, HI) into reactive species e.g. BrO, Br2, BrCl, ClO, OClO and IO. The activation ...
Drones Swoop in to Measure Gas Belched from Volcanoes
(EOS. Science News by AGU, 2018-07-25)
Los gases volcánicos son importantes herramientas de pronóstico de erupciones que se utilizan a menudo en el monitoreo de volcanes. Sin embargo, la recolección de muestras de gas requiere que los científicos ingresen a ...
Implementation of electrochemical, optical and denuder-based sensors and sampling techniques on UAV for volcanic gas measurements: examples from Masaya, Turrialba and Stromboli volcanoes
(European Geosciences Union, 2018-04-26)
Volcanoes are a natural source of several reactive gases (e.g., sulfur and halogen containing species) and nonreactive gases (e.g., carbon dioxide) to the atmosphere. The relative abundance of carbon and sulfur in volcanic ...
