The CO2-vadose project: Numerical modeling to perform a geochemical monitoring methodology and baseline performance assessment for various geochemical variables (gas flux, gas composition, stable isotopes and noble gases) in the carbonate vadose zone

► Monitoring strategy of gas phases based on preliminary modeling. ► Natural CO2 dynamics in the carbonate vadose zone. ► Role of establishing a natural baseline in the monitoring of the CO2 storage sites. ► Lower flux detection limit (LFDL).
