Short summary

We consider the possibility of using the CRDS Picarro G2201-i instrument, originally designed for isotopic CH₄ and CO₂, for measurements of ethane : methane in near-source conditions. The work involved laboratory tests, a controlled release experiment and mobile measurements. We show the potential of determining ethane : methane with 50 ppb ethane uncertainty. The instrument can correctly estimate the ratio in CH₄ enhancements of 1 ppm and more, as can be found at strongly emitting sites.
