From anthropogenic sources to natural oceanic emissions, the concentration of methane in the atmosphere has more than doubled in the last 200 years. Since methane represents a global warming potential 23 times an equivalent mass of carbon dioxide, monitoring this species is of great interest. In terms of anthropogenic emissions, landfills represent a significant source of atmospheric methane. We have developed an in-house algorithm for extracting methane concentrations directly from FTIR spectra for gas samples from a local landfill. In this work, we will describe the method and present some preliminary measurements.
