Using Automated Eddy-covariance Stations for Studying Landfill Methane Emissions

摘要

Our results show that the eddy covariance can be used to quantify the landfill methane emission as long as certain requirements, relatively flat surface and large enough fetch, are met. Our results show that the methane emission rates at the landfill strongly depend on changes in barometric pressure; i.e., rising barometric pressure suppresses the emission, while falling barometric pressure enhances the emission. There was up to 6-fold variation of methane emissions from day-to-day due to changes in barometric pressure.
