Micrometeorological measurements of methane (CH4) and nitrous oxide (N2O) emissions were made at the decommissioned Park Road Landfill in Grimsby, Ontario, Canada between June and August 2002. The influence of precipitation, air temperature, wind speed and barometric pressure on the temporal variability of landfill biogas emissions was assessed. Gas flux measurements were obtained using a micrometeorological mass balance measurement technique [integrated horizontal flux (IHF)] in conjunction with two tunable diode laser trace gas analyser (TDLTGA) systems. This method allows for continuous, non-intrusive measurements of gas flux at high temporal resolution. Mean fluxes of N2O were negligible over the duration of the study (–0.23 to 0.02 [.proportional]gm–2 s–1). In contrast, mean emissions of CH4 were much greater (80.4 to 450.8 [.proportional]gm–2 s–1) and varied both spatially and temporally. Spatial variations in CH4 fluxes were observed between grass kill areas (biogas ‘hot spots’) and the densely grass-covered areas of the landfill. Temporal variations in CH4 fluxes were also observed, due at least in part to barometric pressure, wind speed and precipitation effects.

Key Words: landfill • biogas emissions • temporal variability • methane • nitrous oxide • Micrometeorological measurements • wmr 840-9
