|dc.description.abstract||This study describes the effect of pollution transport between East Asia and South Asia on tropospheric ozone (O3), using model result from the Task Force on Hemispheric Transport of Air Pollution (TF HTAP). Ensemble mean O3 concentration is evaluated against satellite-data and ground observations of surface O3 at four stations in India. Although modeled surface O3concentrations are 10-20ppb higher than those observed, the relative magnitude of the seasonal cycle of O3 is reproduced well. Using 20% reductions in regional anthropogenic emissions, we quantify the seasonal variations in pollution transport between East Asia and South Asia. While there is only a difference of 0.1 to 0.05 ppb in the magnitudes of the regional contributions from one region to the other, O3 from East Asian sources affects the most densely populated parts of South Asia while Southern Asian sources only partly affect the populated parts of East Asia. We show that emission changes over East Asia between 2000 and 2010 have had a larger impact on populated parts of South Asia than vice versa. This study will help inform future decisions on emission control policy over these regions.||en_GB|
