Figure 1. Longitude, latitude, and altitude information of specific aircraft profiles.

Figure 2. Residuals of posterior simulation (posterior - observed) for specific aircraft profiles, shown as a function of date and sample elevation. Units are 10-9 mol mol-1 of CH4 (ppb). Each dot represents one observation.

Figure 3. Statistical summary of residuals for specific aircraft profiles, shown as a function of elevation. Units are 10-9 mol mol-1 of CH4 (ppb). The top figure shows the residuals with no data assimilation (Prior-Observed), and the bottom figure shows the post-assimilation residuals (Posterior-Observed). The black line represents mean residuals, the red lines represent the standard deviation of residuals, and the blue lines represent the upper and lower limits of model-data-mismatch (MDM), binned at every 1-km interval. Statistics in the top-left box of each subplot indicate averaged residuals (mu), a standard deviation of residuals (sigma), averaged model-data-mismatch (MDM), and chi-squared statistics (chi-squared).
