NARSTO EPA_SS_LOS_ANGELES: PM2.5 Particulate Nitrate Measurements from 2001-2002

NARSTO_EPA_SS_LOS_ANGELES_PM25_NITRATE data were collected by the U.S. EPA Particulate Matter Supersites Program using a Cascaded Integrated Collection and Vaporization System (ICVS for Nitrate). Measurements of PM2.5 particulate nitrate, covering particle sizes from 0.1-2.5um, were taken every 10 minutes at Claremont and Rubidoux in Los Angeles County, California, between July 2001 and January 2002. The dataset was contributed by the National Aeronautics and Space Administration (NASA).

Use Cases

• Analyze temporal trends in particulate nitrate pollution based on 10-minute measurement intervals.
• Model source-receptor relationships for airborne particulate matter based on chemical composition data.
• Evaluate and compare air quality measurement methods for PM2.5 constituents.
• Study the size distribution and chemical composition of aerosols in the Los Angeles Basin.

Strengths

• Data collection occurred over a six-month period from July 2001 to January 2002.
• Measurements were taken at a high temporal resolution of every 10 minutes.
• The dataset is part of a coordinated research program (NARSTO) designed to inform air-pollution management policy.

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 and temporal bias inherent to the specific monitoring sites and period.
