NARSTO EPA SS Los Angeles: Scanning Mobility Particle Size Data, 2000-2002

Between December 2000 and February 2002, a TSI Scanning Mobility Particle Sizer collected size characteristics of particles ranging from about 0.014 to 0.673 mm at four sites in Los Angeles County, California. The data were collected as part of the U.S. EPA Particulate Matter Supersites Program to better understand airborne particulate matter. NARSTO, a public/private partnership spanning North America, coordinates the data products.

Use Cases

• Modeling particle size distribution dynamics based on 15-minute measurement intervals.
• Analyzing spatial variability of aerosols based on data from four monitoring sites in the Los Angeles Basin.
• Evaluating measurement methods for atmospheric particulate matter as part of the EPA Supersites Program research.
• Investigating source-receptor relationships for airborne pollutants based on detailed particle count concentrations.

Strengths

• Data collected over a 14-month period from December 2000 to February 2002.
• Measurements cover a specific particle size range from 0.014 to 0.673 mm.
• Data were collected at four distinct geographic sites within Los Angeles County.

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/temporal bias inherent to the specific monitoring campaign.
