From volcanic emissions gases carbon dioxide (CO2) is generally the most abundant with the lowest solubility among the volatile compounds of magmatic liquids and the less susceptible than most other magmatic substances. Thus, volcanic CO2 emission rates could play an important role for constraining the role of magma degassing in the biogeochemical cycle of carbon. However, measurements of CO2 emission rates from volcanoes remain challenging, mainly due to the difficulty of measuring volcanic CO2 against the high level of CO2 in the atmosphere. In this work, infrared multispectral imaging was used to identify and quantify volcanic carbon dioxide |
