(a) Time series of CH4 mole fractions, both observed and simulated, at this CarbonTracker-CH4 observation site. The measured mole fractions (black circles) are plotted along with CarbonTracker-CH4 simulated values with prior fluxes (dark green circles) and posterior fluxes (blue circles).
(b) The time series of model residuals, the difference between the measured and simulated mole fractions, for simulation with prior fluxes (dark green circles) and posterior fluxes (blue circles).
(c) Summary statistics for model residuals from to . Residuals are defined as observed values minus simulated 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 ppb of CH4. The time period over which these quantities are computed is set by the graphs (a) and (b).
