Figure 1. Residuals (simulated - observed) for aircraft profiles at the specified site, shown as a function of date and sample elevation. Units are μmol mol-1 of CO2. Each dot represents one observation.

Figure 2. Statistical summary of residuals (simulated - observed) for aircraft profiles at the specified site, shown as a function of season and elevation. Units are μmol mol-1 of CO2. The shaded area spans the 25th to 75th quantile range, with the median residuals given by the red line. These statistics are generated using all observations falling within the specified months and within each 1000m layer.
