Table 2.

Population-weighted multi-model mean change in O₃ (ppb) in receptor regions due to 20% regional (NAM, EUR, SAS, MDE and RBU), sectoral (PIN, TRN and RES) and global (GLO) anthropogenic emission reductions, for the 6-month O₃ season average of 1-hr. daily maximum. The diagonal, showing the effect of each region on itself, is underlined. All numbers are rounded to the nearest hundredth, and are shown with standard deviations among models.
