Distinguishing between column methane enhancements due to emission events and meteorologically driven variability in column methane enhancements due to routine emissions using a regional type of satellite with a resolution larger than 1.33 km will be challenging, as demonstrated by the case studies examined in this work. Coupling methane column observations with observations of ground concentrations could lead to significant improvements in emission event detection capabilities, however. Local enhancement ratios for ground concentrations due to emission events are orders of magnitude larger than the local enhancement ratios in column concentrations due to emission events (SI Figure ). Spatial coverage for ground concentration observations is currently relatively sparse, limiting the availability of these data for event detection, however, many oil and gas operators are deploying large numbers of fixed-point sensors.
