Comparison of the simulated SO42− concentrations at the superstation from the five experiments and observations (IMAGE)
Caption
The time series of SO42− and SO2 concentrations and the corresponding observations for stations under each simulation scheme are shown. PE_OW used the priori emission and the original unmodified WRF-Chem. DE_OW was performed using the assimilated emissions and the original WRF-Chem. DE_PW used the assimilated emissions inventory and the addition reaction rate parameters from the initial ensemble expectations (prior parameters). DE_4W and DE_1W used assimilated emissions and new reactions added, using reaction rate parameters averaged from the last four posterior averages and from the last posterior average.
