* Derived by scaling 2017/2018 relative VOC/methane ratios observed in O&NG plumes at the Boulder Reservoir to the Peischl et al. [2018] year 2015 DJB methane flux estimate.

** Same as above, but applying the 2017/2018 relative VOC/ethane ratios observed in O&NG plumes at the Boulder Reservoir to the Peischl et al. [2018] year 2015 DJB ethane flux estimate.
