Title: Asian emissions contribute to air pollution in western United States: study
Date: March 2, 2012
[...] To learn more about the mechanisms that transport air pollution across the ocean and determine the effects of Asian air pollution on air quality in the western United States, Lin et al. analyzed in situ and satellite measurements [...]
[...] They find that Asian pollution contributes as much as 20 percent of total ozone during springtime pollution episodes in western U.S. surface air.
[...] in Southern California, the authors estimate that 53 percent of the instances where that limit was exceeded would not have occurred without the contribution from Asian air pollution.
The researchers also find that an index based on satellite observations of Asian pollution plumes could serve as a qualitative early warning indicator, with a lead time of one to three days, of Asian pollution influence on western U.S. air quality.

[...] we examine the mechanisms involved in the transport of Asian pollution plumes into western U.S. surface air through an integrated analysis of in situ and satellite measurements in May–June 2010
[...] a maximum enhancement to ozone occurs over the southwestern U.S., including the densely populated Los Angeles Basin.
[...] Our analysis indicates the potential for Asian emissions to contribute to high-O3 episodes over the high-elevation western USA, with implications for attaining more stringent ozone standards in this region.
[...] using satellite CO column measurements as a qualitative early warning indicator to forecast Asian ozone pollution events in the western U.S. with lead times of 1–3 days.
