Fig. 9: Average diurnal variations in contribution and contribution fractions of the three sources to the change in column-integrated concentrations (CICs) of Ox in the boundary layer in the strongly stable (P2) and moderately stable (P3) periods.

a and b are the contribution of the three sources (namely residual layer contribution, chemical formation, and surface emission) to the change in CICs of Ox in the boundary layer in P2 and P3, respectively. c and d are the contribution fractions of the three sources to the change in CICs of Ox in the boundary layer in P2 and P3, respectively.
