Table 2 Comparison between soil CO₂ fluxes at Furnas Lake and Furnas Village during 19 and 22 August 2014 (this study) and soil CO₂ fluxes calculated in previous study (March 2008 at Furnas Lake and June–July 2009 at Furnas Village). Areas (in m²), soil CO₂ flux, mean, median, minimum, maximum values (expressed in g m⁻² day⁻¹), and skewness are shown. Sp sampling period (year), Np number of points

From: Total (fumarolic + diffuse soil) CO₂ output from Furnas volcano
