^aProxy flux maps were centered at one of the two flux tower sites and created with one of the three methane mole fraction enhancement maps or an averaged map. Each methane mole fraction map is interpolated onto a 0.5 m × 0.5 m resolution grid. An estimate of uncertainty for each integrated flux estimate is provided by calculating an overall emission using values of α (μmol ppm^–1 m^–2 s^–1) that fall within 10 and 90% of the distribution.
