Now and Later
PM model evaluation workshop
Also troubling is the delineated use of measurements and modeled predictions.
…..Measurements are the current tool for strict regulatory applications, and models are used as a planning tool.
………The reality is that measurements really are just estimates of surrounding reality, and in one sense no different from a predictive output from a model.
……. Both these tools need to be more effectively merged to support in unity a host of regulatory and planning applications.
2000-2002 3-Year Average Annual Mean PM modeled predictions. 2.5
Data from AQS 7/9/03. Sites that operated anytime 2000-2002 (n=1239)
Urban and Rural PM2.5 Speciation Networks modeled predictions.
Active Sites as of 1/20/04: EPA data from AQS, IMPROVE data from VIEWS
Supersites IRD Study Domain modeled predictions.
8 modeled predictions.
~ 54 Trends
~ 1050 FRMs
~ 200 cont.
Don’t believe it modeled predictions.
Areas with PAMS Networks modeled predictions.
Air Toxics Monitoring Network: modeled predictions. Pilot sites and proposed trend sites

I’d like to say…………
“Characterize air quality as efficiently as possible in time, space and composition (physical and chemical properties)”
Since any data use or objective relies on a fundamental characterization and benefits by enhancement….
