... sources, experienced elevated surface air pollution under low wind and surface temperature inversion at night and early morning. Survey drives in the basin identified multiple CH 4 and ethane (C 2 H 6 ) sources with distinct C 2 H 6 -to-CH 4 emission plume ratios for coal bed methane (CBM), natural gas...

... ) are lower than inventory predictions (14 Mg hr –1 ) but the proportion of fossil fuel sources is higher than indicated by the inventory. Apportionment of methane emissions between thermogenic and biogenic source types used ethane/methane ratios in aircraft flasks and ground-based source characterization. We...
