NARSTO EPA Supersite Atlanta 1999: Air Chemistry, PM, and Meteorological Measurements

July to September 1999 data from the U.S. EPA Particulate Matter Supersites Program's Atlanta Experiment. The dataset contains air chemistry, particulate matter (PM2.5), and meteorological measurements from a field campaign in Midtown Atlanta, aimed at testing new particle measurement techniques and advancing scientific understanding of atmospheric processes. The data product was developed by the Southern Oxidants Study and Georgia Institute of Technology under the NARSTO partnership.

Use Cases

• Compare and contrast state-of-the-science particulate matter measurement techniques based on the field experiment's instrumentation.
• Analyze relationships between fine particles, ozone, and meteorological conditions in an urban atmosphere based on the combined air chemistry and weather data.
• Evaluate the precision and accuracy of EPA PM monitoring networks based on the supersite's comprehensive measurement campaign.
• Study source-receptor relationships for particulate matter in a polluted urban setting based on the chemical composition data.

Strengths

• Data originates from a focused 4-week field campaign in August 1999 with a specific scientific plan.
• Part of the multi-year (1999-2004) EPA PM Supersites Program designed to address key research priorities.
• Includes measurements from a wide array of instrumentation deployed at a single site for direct comparison.

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 a single location (Jefferson Street, Midtown Atlanta) and a specific season, limiting geographic and temporal generalizability.
