英文摘要: Future changes in anthropogenic emissions of ozone precursors will likely impact seasonal vegetative ozone exposure, W126, in the western U.S. To investigate this, source-receptor relationships are calculated with the GEOS-Chem adjoint model and are separated by location, species, and sector. These are used to project changes in W126 through midcentury following representative concentration pathway (RCP) emissions. The overall behavior of W126 is governed by declining domestic emissions. However, foreign emissions of NOx , non-methane volatile organic compounds, and CO and CH4 abundance can either slow or enhance this trend, depending on scenario. The relative importance of foreign emissions increases as U.S. emissions decline, and, in some cases, the contribution of foreign sources exceeds that of domestic as early as 2020. In 2050, W126 in the western U.S. contributed by Chinese emissions alone, dominated by the industrial sector, is up to 15% higher than in 2000, although such estimates are strongly dependent on scenario. ©2015.
