- Sheet 1 (Calibration_data) contains calibration data, including simulated fluxes, the measured rate of CO2 concentration change observed by the accumulation chamber, and the resulting recalculated measured fluxes.\r
- Sheet 2 (Calibration_raw_data) contains the raw CO2 concentration time-series data for each individual measurement trial conducted during the calibration process.\r
- Sheet 3 (Nea_Kameni_data) contains diffuse flux data and geographic coordinates from fieldwork carried out at the Nea Kameni volcano in Santorini.""" ;
