NARSTO PAC2001: Urban Air Quality and Meteorological Data from Vancouver, 2001

NARSTO_PAC2001_SLOCAN_PARK_GAS_PM_MET_DATA is the North American Research Strategy for Tropospheric Ozone (NARSTO) Pacific 2001 Air Quality Study (PAC2001) product for the Slocan Park site in Vancouver. Data was collected between August 11 and September 1, 2001, and includes measurements of gases, particulate matter (PM) chemical composition, and meteorological variables. The study was organized by the National Aeronautics and Space Administration (NASA) to address policy-relevant issues on ambient particulate matter and ozone.

Use Cases

• Modeling secondary particle formation based on precursor gas measurements (O3, NOx, SO2, NMHCs).
• Conducting receptor modeling for source apportionment based on detailed organic carbon speciation and size-distributed chemical composition.
• Analyzing vertical pollutant profiles based on tethered balloon measurements of O3, wind, temperature, pressure, and humidity.
• Assessing urban background air quality based on data from a residential park site with no major point sources within 3 km.

Strengths

• Includes a wide array of measurements: gases, detailed PM chemical speciation, particle size distributions, and meteorological vertical profiles.
• Site location is precisely documented at 49.23417 N, -123.0475 W, 85 m above sea level, with detailed fetch and source characterization.
• Data collection period is precisely defined from August 11 to September 1, 2001.

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 a specific three-week period in 2001, limiting analysis of seasonal or long-term trends.
