Source-Receptor Relationships Between Precursor Emissions and O and PM Air Pollution Impacts.

Reduced complexity tools that provide a representation of both primarily emitted particulate matter with an aerodynamic diameter less than 2.5 μm (PM), secondarily formed PM, and ozone (O) allow for a quick assessment of many iterations of pollution control scenarios. Here, a new reduced complexity tool, Pattern Constructed Air Pollution Surfaces (PCAPS), that estimates annual average PM and seasonal average maximum daily average 8 h (MDA8) O for any source location in the United States is described and evaluated.
