TL;DR: In this article, the authors demonstrate the successful deployment of a multirotor UAV system with custom-made lightweight payloads for the compositional analysis and gas flux estimation of volcanic plumes.

TL;DR: It is found that aerial strategies reduce uncertainties associated with ground-based remote sensing of SO2 flux and enable near–real-time measurements of plume chemistry and carbon isotope composition and the need to account for time averaging of temporal variability in volcanic gas emissions in global flux estimates is emphasized.

TL;DR: A review on volcanic bromine data achieved from established and cutting edge measurement techniques as well as their treatment and interpretation in recent model experiments can be found in this paper, where the authors provide an overview of the existing and proposed methods for the extraction of bromines from volcanic plumes.

TL;DR: In this article, the influence of emissions from the Nyamuragira-Nyiragongo volcanoes in Africa on Amazonian aerosol properties and atmospheric composition during September 2014 was investigated.

TL;DR: In this article, a multi-rotor drone has been adapted for studies of volcanic gas plumes, which includes improved capacity for high-altitude and long-range, real-time SO2 concentration monitoring, longrange manual control, remotely activated bag sampling and plume speed measurement capabilities.
