Outcome of inversion using CH₃CCl₃ data alone from either the AGAGE network (blue) or NOAA network (red). Upper shows the derived OH concentration, and Lower shows the derived CH₃CCl₃ emissions. Shading indicates the $16\mathrm{t}\mathrm{h}$ and $84\mathrm{t}\mathrm{h}$ percentile range, and the solid lines show the medians. The black lines show the AGAGE-only inversion with an assumed zero temporal correlation-length scale in the model mismatch uncertainty, which removes the long-term drift in the model data residual (Fig. S3). Inset shows CH₃CCl₃ emissions from 2000 to 2014.
