BVLOS UAS Operations in Highly-Turbulent Volcanic Plumes.
Long-range, high-altitude Unoccupied Aerial System (UAS) operations now enable in-situ measurements of volcanic gas chemistry at globally-significant active volcanoes. However, the extreme environments encountered within volcanic plumes present significant challenges for both air frame development and in-flight control. As part of a multi-disciplinary field deployment in May 2019, we flew fixed wing UAS Beyond Visual Line of Sight (BVLOS) over Manam volcano, Papua New Guinea, to measure real-time gas concentrations within the volcanic plume. By integrating aerial gas measurements with ground- and satellite-based sensors, our aim was to collect data that would constrain the emission rate of …
Aerial strategies advance volcanic gas measurements at inaccessible, strongly degassing volcanoes
Aerial measurements using unoccupied aerial systems (UAS) transform our ability to measure and monitor volcanic plumes.
