The application regards five data sets of soil CO<jats:sub>2</jats:sub> fluxes measured with the accumulation chamber methodology at the volcanic areas of Solfatara of Pozzuoli (Italy), Vesuvio cone (Italy), Nisyros (Greece), and Horseshoe Lake (California) and at the nonvolcanic degassing area of Poggio dell'Olivo (Italy). The sGs algorithm was used to generate 100 realizations of CO<jats:sub>2</jats:sub> flux for each area. Probabilistic summaries of these simulations, together with the information given by probability plots, were used (1) to draw maps of the probability that CO<jats:sub>2</jats:sub> fluxes exceed thresholds specific for a background flux, i.e., to define the probable extension of the degassing structures, (2) to calculate the total CO<jats:sub>2</jats:sub> output, and (3) to quantify the uncertainty of the estimation. The results show that the sGs is a suitable tool to model soil diffuse degassing, producing realistic images of the distribution of the CO<jats:sub>2</jats:sub> fluxes that honor the histogram and variogram of the original data. Moreover, the relation between the sample design and the uncertainty of estimation was investigated leading to an empirical relation between uncertainty and the sampling density that can be useful for the planning of future CO<jats:sub>2</jats:sub> flux surveys.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1580009751476070400","@type":"Researcher","foaf:name":[{"@value":"C.
