NARSTO PAC2001 Slocan Park Site Gaseous, Particle, and Meteorological DataEntry ID: NARSTO_PAC2001_SLOCAN_PARK
Abstract: The NARSTO_PAC2001_SLOCAN_PARK_GAS_PM_MET_DATA were collected between August 11 and September 01, 2001 during the Pacific 2001 Air Quality Study (PAC2001).
The Slocan Park (SLPK) site, at 49°14'38.2 N and 123°02'55.1 W and at 85 m a.s.l., was in a typical urban park in a residential neighborhood in Vancouver with an open field of approximately 150 x 300 m2. Residences of one to two stories ... surround the park. The site had good fetch in all directions with no major point sources within a radius of 3 km. Like in much of Vancouver, both deciduous and coniferous trees line the streets around the site. Traffic in the nearby streets is typical of light volume and light duty transportation. The closest street (29th Avenue), approximately 50 m away, is a secondary traffic route with light volume rush hour traffic. The closest major highway, Highway 1A, is about 600 m away where congested rush hour traffic is typical. Measurements at this site were designed to study the urban mixture of primary particles and secondary particles that are expected from conversion of precursors, such as anthropogenic hydrocarbons. Emphasis was also placed on chemical characterization of PM with an eventual goal of receptor modeling, particularly for organic carbon components.
Measurements made at this site included those for gases, such as O3, NOx, total and speciated NOy, SO2, CO, NH3, NMHCs (including mono-terpenes), HCHO and CH3CHO. Particle chemical measurements included size distributed inorganic composition, organic and elemental carbon, and mass from <0.05 to 18 um aerodynamic diameter (AD) using impactors that were sampled twice daily, and size distributed chemical composition from 0.06 to 0.7 um AD at high time resolution using an Aerodyne Aerosol Mass Spectrometer. Detailed organic carbon speciation for many solvent-extractable polar and non-polar homologues of organic compounds were conducted with twice daily high-volume sampling and detailed lab analyses. Black carbon was determined using filter-based optical absorption methods. Sulfur isotope was characterized in PM<2.5 um twice daily on high volume filter samples. Detailed mass measurements were made using several techniques, primarily to assess the performance of the techniques. Particle number size distributions were measured from 0.12 to 0.3 um using an optical probe. Tethered balloon measurements were made at this site. Vertical
profiles, from ground level to 300 m for O3, wind direction and speed, T, P, and RH, were measured four times daily.
The Pacific 2001 Air Quality Study (PAC2001) was conducted from 1 August to 31 September, 2001 in the Lower Fraser Valley (LFV), British Columbia, Canada. The study consisted of individual research projects organized to address several issues on ambient particulate matter and ozone that are important to policy makers. A special issue of Atmospheric Environment [Vol. 38(34), Nov 2004] described specific study objectives (Li, 2004) and presented a series of results papers from the field study. The ground sampling sites during the study were (1) Cassiar Tunnel, (2) Slocan Park, (3) Langley Ecole Lochiel, (4) Sumas Eagle Ridge, and (5) Golden Ears Provincial Park. Aloft measurements were taken from a Convair 580 and a Cessna 188. Selected measurement data were compiled for each site and aircraft and are archived as site-specific data sets.
NARSTO (formerly North American Research Strategy for Tropospheric Ozone) is a public/private partnership, whose membership spans government, the utilities, industry, and academe throughout Mexico, the United States, and Canada. The primary mission is to coordinate and enhance policy-relevant scientific research and assessment of tropospheric pollution behavior; activities provide input for science-based decision-making and determination of workable, efficient, and effective strategies for local and regional air-pollution management. Data products from local, regional, and international monitoring and research programs are available.
