(a) Time series of column-average dry air CO2 mole fractions ("XCO2"), both simulated and retrieved, at this TCCON observation site. In the top panel, retrieved XCO2 (open black circles) is plotted along with CarbonTracker simulated values (filled light blue circles). All times are in UTC.

(b) The time series of model residuals--the difference between the simulated and retrieved XCO2--shown with dark green filled circles. All times are in UTC.
