Extended Data Fig. 3: Consistency of bottom-up and top-down studies.
From: Large methane mitigation potential through prioritized closure of gas-rich coal mines
We independently calculate the correlation coefficient between bottom-up studies (emissions from Edgar V5.05 are excluded as they are not independent from CEDS9) and top-down analyses. Our estimate is much more consistent with all top-down studies compared to previous bottom-up studies in terms of correlation, except for CEDS (or Edgar V5.0). It is not surprising that CEDS (or Edgar V5.0) has slightly higher correlation than our study, as it was used as prior information by all of these top-down analyses.
