NARSTO EPA St. Louis: Air Chemistry and Particulate Matter Data from 2001-2003

NARSTO_EPA_SS_ST_LOUIS_AIR_CHEM_PM_MET_DATA were obtained between April 11, 2001 and July 21, 2003 during the St. Louis - Midwest Supersite program. The dataset includes 5-minute to 24-hour measurements of PM 2.5 black carbon, organic carbon, metal composition, mass concentration, and meteorological parameters. It was collected by the U.S. EPA Particulate Matter Supersites Program and is hosted by the National Aeronautics and Space Administration.

Use Cases

• Modeling source-receptor relationships for particulate matter based on detailed chemical speciation.
• Analyzing correlations between meteorological conditions and PM concentrations based on concurrent wind, temperature, and radiation data.
• Evaluating measurement methods for PM mass and composition based on comparisons between continuous monitors and integrated filter analysis.
• Studying temporal trends in carbonaceous aerosols based on 1-hour and 24-hour elemental and organic carbon measurements.

Strengths

• Data collection spans over two years, from April 2001 to July 2003.
• Includes multiple measurement types and temporal resolutions, from 5-minute to 24-hour data.
• Focuses on a major, geographically isolated urban center (St. Louis) with diverse local industrial sources.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic and temporal bias inherent to a single supersite study from 2001-2003.
