Supporting Information Effect of regional precursor emission controls on long-range ozone transport: 1. Short-term changes in ozone air quality

Table S1 shows the annual average change in ozone, spatially-weighted over the receptor region, due to 10% anthropogenic NOx emission reductions in each source region. Table S2 shows these results for experiments where NOx, NMVOCs and CO are reduced simultaneously from three source regions. Comparing with the three-month population-weighted indicators in Tables 2 and 4 of the main paper, the strongest source-receptor pairs are generally the same, but there are important quantitative differences, suggesting that the quantification of long-range transport can vary strongly with the ozone concentration metric used.
