NARSTO EPA_SS_HOUSTON: Aerosol Size Distributions from Houston Supersites, 2000-2001

NARSTO EPA_SS_HOUSTON Differential Mobility Analyzer Data consists of aerosol size distributions and number concentrations collected in Houston, Texas. Measurements were taken at multiple sites from August 2000 to November 2001 as part of the U.S. Environmental Protection Agency's Supersite program. The data were collected by NASA to characterize particulate matter composition and sources in Southeastern Texas.

Use Cases

• Modeling urban aerosol dynamics based on size distribution data collected at multiple sites.
• Analyzing temporal trends in particulate matter concentration over a 15-month period.
• Comparing air pollution characteristics between different monitoring locations (Aldine, HRM3, La Porte, Deer Park).
• Supporting health effects studies with physical characterization data of fine particulate matter.
• Testing and validating new methods for fine particulate matter characterization.

Strengths

• Data collected over a 15-month period from August 2000 to November 2001.
• Measurements taken at multiple sites (Aldine, HRM3, La Porte, Deer Park) for spatial comparison.
• Part of a coordinated EPA Supersite program with defined goals for characterization and source identification.

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 campaign.
