Fig. 4: Comparison of net atmospheric emissions derived using PBREAK and CATHARE with satellite and tall tower estimates used in our analysis.
From: Methane emissions from the Nord Stream subsea pipeline leaks
Total CH4 emissions from the Aliso Canyon blowout45 are shown for comparison. The symbols and error bars for inversions 1, 2 and 4–6 represent central (average) estimates and ranges, respectively. It is noted that initial tall tower inverse estimates are not plotted here, nor inversion 3, which derives only a minimum estimate of atmospheric CH4 emissions (see text and Supplementary Table 1).
