Over 23 days from August 13 to September 5, 2001, the Pacific 2001 Air Quality Study collected gaseous, particle, and meteorological data at the Sumas Eagle Ridge site. Measurements were made by the LARC_ASDC organization to study aerosol types, sources, and interactions between biogenic emissions and urban pollution.
Use Cases
- Analyze diurnal patterns of O3, NOx, and CO concentrations to study boundary layer evolution.
- Correlate NH3 measurements with particle mass and organic carbon data to assess agricultural emission impacts.
- Use size-distributed mass and inorganic composition data to model aerosol optical properties.
- Compare VOC, terpene, and carbonyl measurements from light to dark hours to study nighttime chemistry.
- Integrate TEOM continuous mass measurements for particles <10 μm with AMS high-time resolution data for the last 5 days.
Strengths
- Data collected over a continuous 23-day period in August-September 2001.
- Site was uniquely elevated at 300 m above sea level to study boundary layer interactions.
- Includes high-time resolution AMS measurements for 5 days covering particle size distribution from 0.06 to 0.7 μm.
Limitations
- Sample size is limited to one geographic site and a single seasonal period.
- High-time resolution AMS data is only available for the final 5 days of the study.
- No row or column count is provided, making data volume unknown.
