NARSTO EPA Supersite: Pittsburgh Air Quality Study Gas and Particulate Data, 2001-2002

NARSTO_EPA_SS_PITTSBURGH_GAS_PM_PROPERTY_DATA is the North American Research Strategy for Tropospheric Ozone (NARSTO) Environmental Protection Agency (EPA) Supersite Pittsburgh Gas Concentration and Particulate matter (PM) Physical Properties Data product. Data was obtained between May 23, 2001 and September 1, 2002 during the Pittsburgh Air Quality Study (PAQS). The dataset provides particulate matter composition data, including measurements of PM10 and PM2.5 mass, particle surface area, size distribution, and surface air concentrations of gases like O3, NO, and SO2.

Use Cases

• Analyze temporal trends in urban air pollution based on the 14-month measurement campaign from July 2001 to September 2002.
• Model relationships between particulate matter size distribution and gas concentrations based on data from Scanning Mobility Particle Sizers and VOC measurements.
• Evaluate source apportionment of PM in the Pittsburgh region based on the multi-component monitoring strategy described.
• Calibrate next-generation aerosol monitoring instruments based on the instrument development and evaluation study component.

Strengths

• Data collection spanned a 14-month intensive monitoring campaign from July 2001 to September 2002.
• Includes measurements from a central supersite and five satellite sites to characterize spatial variation.
• Covers multiple particulate matter properties and gas concentrations as listed in the detailed description.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is from 2001-2002; freshness should be verified for contemporary applications.
