Key methane observations. Time series of CH4 (ppb) between 28 November 2015 and 9 January 2016 at the four observation locations within the Uintah Basin (HPL, orange line; ROO, green line; CSP, purple line; FRU, black line). The two shaded periods (28 November 2015–6 December 2015 and 1–6 January 2016) represent two cold-air pool periods (Events A and B, respectively) chosen for this study where significant clouds, mixing or precipitation did not occur.
