Methane (CH4 ) plays a critical role in the radiation balance and chemistry of the atmosphere. The major anthropogenic sources are anaerobic production from landfills, ruminant animals and their waste, release from the mining and use of fossil fuel, burning of biomass, etc.. On average, over the global scale, landfill methane emissions contribute between 10-19% of the anthropogenic methane burden into the atmosphere
CH4 is a potent greenhouse gas - about 25 times stronger than CO and outgases from reservoirs, landfills and permafrost soils. The ETG 6900 can reliably & selectively measure methane in low ppm concentrations without the need for frequent recalibrations.
It is thus ideally suited for study on emission CH4 monitoring in landfill or remote-site applications, e.g. in environmental research.
