Each station is equipped with infrared (IR) sensors for the precise measurement of CO₂ concentrations, along with meteorological sensors that record key environmental parameters including air temperature, atmospheric pressure, wind speed and direction, and precipitation. These data enable the estimation of CO₂ soil fluxes through the application of the method proposed by Gurrieri and Valenza (1988) (see Methods for details). The ETNAGAS network represents a high-resolution geochemical surveillance system and constitutes an integral component of the national framework for monitoring volcanic gas emissions. Its primary objective is to contribute to the assessment of the volcanic activity state of Mount Etna through systematic and spatially distributed measurements of gaseous emissions. completed Liuzzo, Marco Istituto Nazionale di Geofisica e Vulcanologia - INGV marco.liuzzo@ingv.it https://orcid.org/0000-0002-3099-7505 ORCID pointOfContact notPlanned https://data.ingv.it/dataset/cover/1118.jpg thumbnail image/jpeg EU open data Local Spatial scope 2019-05-22 publication Soil CO2 Vocanic CO2 concentration Etna Geochemical monitoring theme otherRestrictions Creative Commons Attribution 4.0 International (CC BY 4.0) otherRestrictions no limitations to public access http://publications.europa.eu/resource/authority/licence/CC_BY unclassified 1000 eng utf8 Sicily - Etna 3C 15.0822, 37.6086 Agro 14.8989, 37.5336 Albano 14.9422, 37.7253 brunek 15.0742, 37.8081 Maletto 14.8997, 37.7936 msm1 14.9836, 37.8258 P78 15.1433, 37.6953 Parcoetna 15.0231, 37.6306 Roccacampana2 15.1369, 37.8003 SML1 14.9208, 37.6569 SML2 14.905, 37.6636 SV1 15.1353, 37.6967 Fondachello 15.2167, 37.7706 Passop 15.0456, 37.8669 Primoti 15.118, 37.7021 Ripenaca 15.0975, 37.7625 P39 14.8837, 37.5493 N1 14.6971, 37.3248 N2 14.7172, 37.3391 Istituto Nazionale di Geofisica e Vulcanologia (INGV) ufficiogestionedati@ingv.it http://www.ingv.it distributor https://oedatarep.ct.ingv.it/records/03adr-hbp54 WWW:LINK-1.0-http--link other homepage accessPoint dataset m 1 Commission Regulation (EU) No 1089/2010 of 23 November 2010 implementing Directive 2007/2/EC of the European Parliament and of the Council as regards interoperability of spatial data sets and services 2010-12-08 Publication This data set is conformant with the INSPIRE Implementing Rules for the interoperability of spatial data sets and services true The monitoring stations of the ETNAGAS network were entirely developed by the Istituto Nazionale di Geofisica e Vulcanologia (INGV), Palermo section. These stations are capable of continuously measuring several environmental and geochemical parameters, including soil CO₂ concentration, atmospheric temperature, pressure, relative humidity, rainfall, wind speed, and wind direction. Data are acquired at hourly intervals and automatically transmitted to the monitoring center at INGV-Palermo. It should be noted that not all stations are equipped with the full suite of meteorological sensors. CO₂ fluxes from the soil can be derived from the recorded data using the dynamic (or dilution) method described by Gurrieri and Valenza (1988). This method is based on measuring the CO₂ content in a mixture of soil gas and atmospheric air (Cd), obtained using a probe inserted approximately 50 cm into the ground. Soil gases enter the probe through its base and are mixed with ambient air; this mixture is then pumped into an infrared (IR) spectrophotometer, which measures the CO₂ concentration. According to Gurrieri and Valenza, the measured diluted concentration (Cd) is empirically related to the actual soil CO₂ flux (ϕCO₂) through a relationship established under laboratory conditions, across a range of gas permeabilities (0.36–123 mm²) and pumping flow rates (0.4–4.0 L/min) [Camarda et al., 2006a, 2006b].
