Abstract: | There is an increasing interest on the intercontinental transport of air pollution among the three main emission regions at
northern mid-latitudes: North America, Europe, and East Asia. Air pollutants with sufficient long lifetime can be transported
from one continent to another. Observations from ground sites, aircraft and satellites have demonstrated this intercontinental-scale
transport of air pollutants in the free troposphere. Numerical models have been applied to understand the pathways of the
transport and the impact of intercontinental pollution transport. This paper reviews current observational evidence and modeling
studies of intercontinental transport of ozone and its precursors, and the resulting impacts on air quality. |
