“…Soil CO 2 flux was measured using a West Systems Fluxmeter (West Systems) based on the accumulation chamber method (e.g., Chiodini et al, 1998), with accuracy and repeatability of -12.5% (Evans et al, 2001) and ±10% (Chiodini et al, 1998), respectively. An opaque chamber was used and vegetation within the chamber footprint area was clipped so that only soil CO 2 efflux (ecosystem respiration + leakage) was 6 measured.…”

“…The biogas flux measurements were carried out with the stationary method of accumulation chamber (Witkamp, 1969;Kucera and Kirkham, 1971;Kanemasu et al, 1974;Parkinson, 1981, Tonani andMiele, 1991;Chiodini et al, 1996;Chiodini et al, 1998) considering the lower weather dependence conditions indicated by Trégourès et al (1999). This method allows to measure the increase of concentration of a given gas specie inside a sealed chamber, open only on the bottom, in touch with the ground; a non stationary version has been used to measure the diffused gas emissions in landfills (Cossu et al, 1997).…”

“…A detailed description of this instrumentation has been reported by Chiodini et al (1996Chiodini et al ( , 1998 and in Raco et al (2005). In Raco et al (2005), also the influence of weather parameters, especially of atmospheric pressure, was considered.…”

“…Soil CO 2 effluxes (expressed in g m -2 d -1 ) were measured at all selected sampling sites using the method of the dynamic accumulation chamber [e.g., Parkinson 1981, Chiodini et al 1998, Farrar et al 1995. CO 2 effluxes were measured in at least duplicate during each survey, and the arithmetic average of the values was considered for the temporal analysis of data.…”
