Tropospheric ozone change from 1980 to 2010 dominated by equatorward redistribution of emissions.

ABSTRACT: Since 1980, anthropogenic emissions of ozone precursors have decreased in developed regions, but increased in developing regions, particularly East and South Asia, redistributing emissions equatorwards^1-4. Modeling studies have shown that the tropospheric ozone burden (B _O3) is much more sensitive to emission changes in the tropics and Southern Hemisphere (SH) than other regions^5-9. However, the effect of the spatial redistribution of emissions has not been isolated. Here we use a global chemical transport model to consider changes in anthropogenic short-lived emissions from 1980 to 2010, and separate the influence of changes in the spatial distribution of emissions from the total emission increase, on B _O3 and surface
