Short summary
Here, we present the results of tunable diode laser observations at four quiescent volcanoes: Nea Kameni, Hekla, Krýsuvík, and Vulcano Island, which display a range of fumarolic activity from weak to moderate. This study contributes to better characterising the typical levels of CO2 emission from such feeble volcanic point sources, suggesting that the cumulative contribution from weakly degassing volcanoes may be significant at global scale.
