Table 2 Accumulation measurements. Concentration rate α and saturation values C s retrieved by fitting Eq. (3) to the experimental data. In the last column we list the respective flux of CO2 (at Standard Temperature and Pressure). The sites were labelled in the first column (see the text for details).

From: Continuous in situ measurements of volcanic gases with a diode-laser-based spectrometer: CO2 and H2O concentration and soil degassing at Vulcano (Aeolian islands: Italy)
