Particle-Bound Polycyclic Aromatic Compound Measurements from Fresno Supersite

September 1999 to December 2006 data contains continuous five-minute averaged measurements of particle-bound polycyclic aromatic compounds (PAC) from a Photoelectric Aerosol Sensor monitor. The data was collected at the Fresno EPA Supersite to characterize particulate matter. It was produced by the NARSTO partnership and archived by the LARC_ASDC organization.

Use Cases

• Analyze temporal trends in PAC concentrations from continuous five-minute averaged data to identify pollution patterns.
• Correlate PAC measurements with other supersite data to study source-receptor relationships for particulate matter.
• Use the long-term monitoring record from 1999-2006 to assess seasonal or annual variations in aerosol-bound pollutants.
• Evaluate the performance of the Photoelectric Aerosol Sensor (PAS) monitoring method for PAC detection in an urban setting.

Strengths

• Over 7 years of continuous monitoring data from September 1999 to December 2006.
• High temporal resolution with data averaged over five-minute periods.

Limitations

• Sample inlet had no specified particle size separation, limiting analysis of specific particulate size fractions.
• Data is geographically limited to a single urban monitoring site in Fresno, California.
• Dataset is temporally stale, with collection ending in 2006 and no recent updates.
