• The LRTP/HTAP flow of air pollutants is likely to increase as overseas economies grow.• Pollutant influx leads to significant exceedances of O3 PM NAAQS in some regions• Even after domestic controls, some US areas will be no-compliant because of LRTP

Asian Dust Cloud over N. America
On April 27, 1998 the dust cloud arrived in North America.
Regional average PM10 concentrations increased to 65 g/m3
In Washington State, PM10 concentrations exceeded 100 g/m3
Asian Dust 100 g/m3
Hourly PM10
Origin of Fine Dust Events over the US
Sulfate is local, no major spikes
Gobi dust transport in springSahara dust import in summer
Fine dust spikes over the entire US are mainly from intercontinental transport

Summary • Global Sensing – Modeling Revolution – ‘May you live in interesting
times’– We are in the midst of an observational revolution (satellites, monitoring
networks).– The global distribution and transport of some pollutants can be monitored daily– Global models are maturing into effective analytical and predictive tools
• Results to Date: – Compelling evidence for global-scale transport of PM and Ozone
– Qualitative evidence of ‘extra-jurisdictional’ impact on the US air quality– Potential for quantification of natural and non-US impact
• Such massive job will require:– International, interagency, interdisciplinary collaboration.– Open flow of data/knowledge– Scientific ‘value-adding chains’
FUTURE
For instance,
• Health– effects/outcomes associations (PHASE)– Public health warnings/forecasting
• Air program support– defining attainment/nonattainment areas
(and projection, current practice)– developing emission strategies– accountability
• Environmental– Ecosystem deposition assessments/support– AQ trends in National Parks– Regional haze assessments
• Atmospheric science– Diagnosing emissions and models
Benefit from Air quality characterizations
And benefit even more from rich (t,s,c) AQ characterizations
Building an integrated observation-modeling complex: an air program perspective
• Health– effects/outcomes associations (PHASE)– Public health warnings/forecasting
• Air program support– defining attainment/nonattainment areas
(and projection, current practice)– developing emission strategies– accountability
• Environmental– Ecosystem deposition assessments/support– AQ trends in National Parks– Regional haze assessments
• Atmospheric science– Diagnosing emissions and models
Benefit from Air quality characterizations
And benefit even more from rich (t,s,c) AQ characterizations
Note: IGACO; AQ, ox eff., strat-O3, climate
Consequently
• A simple overarching goal or vision,
– Strive for maximum and efficient AQ characterization in time, space and compositional terms
• the intersecting or common link between air programs and satellite data and integrated advanced systems
• Assimilation of data to improve
– air quality models for forecast
– Current and– Retrospective
assessments
• Global-Regional Air Quality Connections
• Climate-AQ connections
