Table 1 CO2 fluxes (in t day−1) and standard deviation (±1 σ) calculated in the investigated areas based on TDL and accumulation chamber surveys. The plume transport vertical speed (in m s−1) is also given for each site. Fumarolic CO2 outputs are given for each fumarole emissions (WJ and ST at Furnas Lake; CdA and CG at Furnas Village). Soil CO2 flux values are given for the entire areas (Lake and Village, respectively). Total CO2 emissions (fumarolic + soil) are also given
