NARSTO EPA_SS_LOS_ANGELES: PM2.5 Particulate Carbon Measurements in Los Angeles, 2002

Los Angeles Basin air quality data collected from January to May 2002 at a Claremont, California monitoring site. The dataset contains PM2.5 particulate carbon measurements covering particle sizes from 0.1 to 2.5 micrometers, recorded every 10 minutes using a Cascaded Integrated Collection and Vaporization System. It was produced under the U.S. EPA Particulate Matter Supersites Program and is hosted by the National Aeronautics and Space Administration.

Use Cases

• Analyze temporal patterns of fine particulate carbon based on 10-minute measurement intervals mentioned in the description
• Model source-receptor relationships for air pollution based on the supersite program's research objectives
• Evaluate measurement methods for airborne particulate matter based on the program's goal of testing new methods
• Study the size distribution of carbonaceous aerosols based on the 0.1-2.5um size range coverage

Strengths

• Data collected at a high temporal resolution of every 10 minutes
• Specific size range coverage from 0.1 to 2.5 micrometers for particulate carbon
• Clear temporal coverage from January 14, 2002 to May 24, 2002
• Part of a coordinated research program (EPA Supersites) with defined scientific objectives

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 bias inherent to a single Los Angeles Basin monitoring site
