(a) Time series of CO2 mole fractions, both simulated and observed, for this dataset. In the top panel, measured mole fractions (black points) are plotted along with simulated values (open circles) and withheld values (open triangles).
(b) The time series of model residuals--the difference between the simulated and measured mole fractions--shown with open circles corresponding to the given version plotted along with the difference between the withheld and measured mole fractions--shown with open triangles corresponding to the given version.
(c) Summary statistics for model residuals from to . Residuals are defined as simluated values minus observed values. "Bias" is the mean of the residuals; "std. dev." is the standard deviation, and RMSE is root-mean-square error. All quantities are in ppm of CO2. The time period over which these quantities are computed is set by the graphs (a) and (b).

(d) Taylor diagram for this dataset.
