Halogen activation in the plume of Masaya volcano: field observations and box model investigations
Rüdiger, Julian; Gutmann, Alexandra; Bobrowski, Nicole; Liotta, Marcello; De Moor, J. Maarten; Sander, Rolf; Dinger, Florian; Tirpitz, Jan-Lukas; Ibarra, Martha; Saballos, Armando; Martínez, María; Mendoza, Elvis; Ferrufino, Arnoldo; Stix, John; Valdés, Juan; Castro, Jonathan M.; Hoffmann, Thorsten (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 ... -
Implementation of electrochemical, optical and denuder-based sensors and sampling techniques on UAV for volcanic gas measurements: examples from Masaya, Turrialba and Stromboli volcanoes
Rüdiger, Julian; Tirpitz, Jan-Lukas; de Moor, Joost Maarten; Bobrowski, Nicole; Gutmann, Alexandra; Liuzzo, Marco; Ibarra, Martha; Hoffmann, Thorsten (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 ...
