(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. (b) The time series of model residuals--the difference between the simulated and measured mole fractions--shown with filled circles corresponding to the given version.
