NARSTO EPA SS Los Angeles: Aerodynamic Particle Size Data, 2000-2001

December 2000 to September 2001 data on aerodynamic particle size distributions in Los Angeles County, California. The dataset contains particle count concentrations for 52 size channels from 0.5 to 20 mm, measured every 15 minutes using a TSI Aerodynamic Particle Sizer (APS) in a mobile trailer. It was collected under the U.S. EPA Particulate Matter Supersites Program and is provided by the National Aeronautics and Space Administration.

Use Cases

• Modeling particulate matter size distributions based on 52 aerodynamic size channels.
• Analyzing temporal trends in aerosol concentrations based on 15-minute measurement intervals.
• Researching urban air pollution sources and transport in the Los Angeles Basin based on mobile monitoring data.
• Evaluating aerosol measurement methods as part of the EPA Supersites Program's objectives.

Strengths

• Data collected over a 10-month period (December 2000 to September 2001).
• High temporal resolution with measurements taken every 15 minutes.
• Detailed size characterization across 52 channels from 0.5 to 20 mm.

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 2000-2001; freshness should be verified for contemporary applications.
