Methane, the second most important greenhouse gas after carbon dioxide, is emitted from a variety of sources, including biological sources—such as landfills, wastewater treatment plants, and dairies—and fossil sources–such as leaks in the natural gas distribution infrastructure, refineries, and power plants. Large uncertainties in current estimates of methane emissions impede our ability to develop effective methane reduction measures. In fall 2016, the Air District collaborated with UC Davis Professor Steve Conley to measure methane fluxes from aircraft over Bay Area sources. Professor Conley and UC Davis partners applied an innovative measurement technique by flying around methane sources and estimating measurement-based emission fluxes. This talk will present study methods and compare measurement-based methane emission flux estimates with those from traditional ‘bottom-up’ inventories and facility-reported estimates.
