CH4Time Series

Plots of time series of CH4 mole fractions, prior, post-assimilation and observed, at the CarbonTracker observation sites, and histograms of residuals at the sites for selected periods (residuals are the difference between the post-assimilation and measured mole fractions).

Aircraft Profiles

Plots include residuals (simulated - observed) for aircraft profiles at the observation sites, shown as a function of date and sample elevation. and statistical summaries of residuals for aircraft profiles at the observation sites, shown as a function of season and elevation.
