The emissions of CO₂ and other volatiles from the world's subaerial volcanoes.

ABSTRACT: Volcanoes are the main pathway to the surface for volatiles that are stored within the Earth. Carbon dioxide (CO₂) is of particular interest because of its potential for climate forcing. Understanding the balance of CO₂ that is transferred from the Earth's surface to the Earth's interior, hinges on accurate quantification of the long-term emissions of volcanic CO₂ to the atmosphere. Here we present an updated evaluation of the world's volcanic CO₂ emissions that takes advantage of recent improvements in satellite-based monitoring of sulfur dioxide, the establishment of ground-based networks for semi-continuous CO₂-SO₂ gas sensing and a new approach to estimate key volcanic gas parameters based on magma compositions.
