The Commission’s work is organised across four complementary workgroups, bringing together researchers working with different approaches to measuring and understanding volcanic gases.
Direct Sampling
Focuses on the collection and analysis of volcanic gases directly from vents, fumaroles and other accessible sources, providing detailed information on gas composition and its variations.
Diffuse Degassing
Addresses the measurement and interpretation of gases released diffusely through volcanic edifices and surrounding areas, including methods for quantifying emissions and understanding their spatial and temporal variability.
Remote Sensing
Develops and applies remote-sensing techniques to detect and quantify volcanic gases from a distance, including ground-based, airborne and satellite observations.
In Situ Plume Measurements
Focuses on measurements made within volcanic gas plumes, using instruments deployed in or close to the plume to characterise gas composition, emissions and plume processes.
Together, these workgroups cover complementary scales and measurement approaches, advancing our understanding of volcanic degassing and the methods used to monitor it.
