Fig. 3: Observationally derived and posterior CFC emissions.

Emissions estimates are shown for (a) CFC-11, (b) CFC-12, and (c) CFC-113. In each panel, an inset shows results after 2010 while the main panels cover 1955 to 2016. Red and blue lines show results for observationally derived emissions using the SPARC MMM and constant lifetimes, respectively. The gray line indicates the mean Bayesian estimate, the gray shaded region indicates the 95% confidence interval and the dashed line indicates the 99% confidence interval.
