TL;DR: The carbon isotope composition of mean global volcanic gas is considerably heavier, at -3.8 to -4.6 per mil (m) than the canonical mid-ocean ridge basalt value of -6.0 m as discussed by the authors.

TL;DR: In this article, the authors compare UAS-derived gas timeseries to simultaneous crater rim multi-GAS data and UV camera imagery to investigate early plume evolution, and observe good agreement between time-averaged molar gas ratios obtained from simultaneous UAS and ground-based multiGAS acquisitions, and conclude that UAS measurements made in the young, less diluted plume reveal additional short-term periodic structure that reflects active degassing through discrete, audible gas exhalations.

TL;DR: In this article, a time series of carbon fluxes into and out of the Earth's interior through the past 200 million years is used to compare the relative importance of different tectonic settings throughout Earth's history to carbon outgassing.

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: In this paper, the authors analyzed open-access data from the permanent air quality monitoring networks operated by the Hawai'i Department of Health (HDOH) and National Park Service (NPS), and report on measurements of atmospheric sulfur dioxide (SO2) between 2007 and 2018 and PM2.5 (aerosol particulate matter with diameter < 2.5 μm) between 2010 and 2018.
