NARSTO PAC2001: Sumas Mountain Air Quality Measurements, August-September 2001

Sumas Eagle Ridge in British Columbia, Canada, was the site for this atmospheric data collection during the Pacific 2001 Air Quality Study from August 13 to September 5, 2001. The dataset likely contains gaseous, particulate, and meteorological measurements from a forest clearing site 300 meters above sea level, intended for studying aerosol sources and visibility. It was produced by the National Aeronautics and Space Administration (NASA).

Use Cases

• Modeling aerosol optical properties based on particle chemical and physical measurements mentioned in the description.
• Analyzing diurnal changes in gas and particle chemistry from light to dark hours, as referenced in the site description.
• Studying the interaction between biogenic volatile organic compounds (VOCs) and urban pollution, a stated objective of the study.
• Investigating the contribution of ammonia (NH3) from agricultural sources to particle mass formation, a key focus area.

Strengths

• Data collection spanned a focused 24-day period from August 13 to September 5, 2001.
• Site location is precisely specified at 49.05166 N, -122.24666 W, 300 m above sea level.
• Measurements cover a multi-faceted suite of atmospheric components: gases, particles, and meteorology.

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 a single elevated site studied over three weeks in 2001.
