NARSTO PAC2001: Air Quality and Meteorological Data for Greater Vancouver, 2001-2002

NARSTO_PAC2001_GVRD_CAPMON_AIR_QUALITY_DATA is a supplemental air quality dataset from the Pacific 2001 study. It contains monitoring data from 20 sites in the Greater Vancouver Regional District and the Canadian Air and Precipitation Monitoring Network, collected from January 1, 2001, to January 1, 2002. The data were compiled by the North American Research Strategy for Tropospheric Ozone (NARSTO) and are archived by NASA.

Use Cases

• Modeling spatial pollutant distribution based on data from a network of 20 monitoring sites.
• Analyzing temporal trends of pollutants related to acid rain based on long-term monitoring objectives.
• Evaluating long-range transport models using regionally representative data from CAPMoN sites.
• Studying the relationship between meteorological conditions and air quality using 5-minute resolution weather measurements.

Strengths

• Data collection involved enhanced quality assurance and quality control activities during the study period.
• Includes meteorological measurements at a high temporal resolution of 5 minutes.
• Combines urban (GVRD) and non-urban, regionally representative (CAPMoN) monitoring perspectives.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The primary study period (PAC2001) was only two months (August-September 2001), though supplemental data covers a full year.
