The source sector categories are taken from the EDGAR inventory. Black dots represent the measured increments over the simulated background. Error bars on simulated peaks are the RMSE of simulated vs measured mole fractions using EDGAR (20.8 ppb, see Fig. 4), error bars on the measured increments include both the σ of hourly measurements and the σ of simulated background for that hour.
