NARSTO EPA Supersite (SS) Fresno, Beta Attenuation Monitors (BAM), Particulate Mass Concen

Measurements from May 1999 onward, collected by two Beta Attenuation Monitors (BAM) for PM10 and PM2.5 at the Fresno Supersite. This dataset was produced by the NARSTO/EPA Supersites Program to characterize particulate matter, its sources, and health effects. The site is located at 3425 First Street in Fresno, California.

Use Cases

• Analyzing temporal trends in PM2.5 and PM10 concentrations based on continuous monitoring data.
• Comparing measurement methodologies for particulate matter based on the described beta attenuation technique.
• Studying urban air quality and source-receptor relationships based on the described Fresno Supersite location and environment.
• Calibrating or validating air quality models based on high-temporal-resolution particulate mass data.

Strengths

• Data collection began in May 1999, providing a long-term record for analysis.
• Measurements are from a dedicated EPA Supersite, suggesting a research-grade monitoring setup.
• Includes parallel measurements for both PM10 and PM2.5 size fractions from two BAM instruments.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• File formats include BIN, PDF, ISO, and HTML, which may require specific tools for access and processing.
