[edit] Exceptional Air Pollution Events: Regional and Intercontinental Dust and Smoke
The national air quality standards for PM2.5 and ozone provide for the exclusion of data for a given day when it is strongly influenced by "exceptional events" (EE), such as smoke from wildfires or windblown dust. In order to apply for EE exclusion, states must provide appropriate documentation to support the dominance of uncontrollable sources on that day. Most of EE days are due to regional or continental-scale smoke and dust events. Here we report the candidate methodologies that are being developed for the quantification and documentation of EE over the US, including: (1) Observed/modeled pollutant transport based on trajectory and regional models; (2) Spatial pattern of pollutant derived from surface (AIRNOW, FRM, Visibility) and satellite data (TOMS, GOES, AVHRR, SEAWiFS, MODIS); (3) Temporal pattern analysis; (4) Chemical fingerprinting and source apportionment. The characteristics and initial climatology of EE over the US will also be be presented.
