NARSTO PAC2001 Golden Ears Provincial Park Gaseous and Particle Data |
The Golden Ears Provincial Park (GEP) site was situated at 49.27783 N and -120.51544 W and at 220 m a.s.l., about 45 km east of Vancouver in the Coastal Mountains. The sampling site, located at the park ranger headquarters compound, was in a small forest clearing of about 65 x 130 m and was surrounded by tall coniferous trees (dominated by Western Hemlock, Western Red Cedar, and Douglas Fir, typically seen in the Coastal Mountains) with canopy heights about 10-15 m near the site but rising to over 30 m in the park in general. The temporary labs were about 10 m away from the closest trees. The closest urban area, Maple Ridge, is about 8 km to the south. The measurements were during August 6 to 11, 2001.
Different from the other sites, the Golden Ears Provincial Park site was dedicated to the question of secondary biogenic particles production from forestry precursors. The 1995 emission inventories for the LFV indicate strong monoterpene emissions from forests in the Coastal Mountains and the Cascade Ranges. A previous study here showed significant ambient concentrations of terpenes (Boudries and Bottenheim, 2001). Monoterpenes are converted into particles in the gas phase with high yields (Hoffmann et al., 1998). While the forests were known to release monoterpenes, the magnitude of the contribution to fine particles in the LFV was not clear. Measurements at the GEP site were designed to provide information on secondary biogenic particle production from forestry precursors, such as monoterpenes.
Table 1 shows the selected measurements at this site that are being archived. Overall measurements included, gas phase measurements that emphasized the biogenic VOCs, particularly monoterpenes such as a- and b-pinenes, along with SO2, O3, and some aromatic hydrocarbons (Shantz et al., 2004). OVOCs, including light molecular weight alcohols and carbonyls, were also measured. Particle chemical characterization included organic carbon speciation, such as terpene oxidation products Cheng et al., 2004), inorganic composition, water soluble organic carbon, carbon isotope (Huang et al., 2002), and total organic/elemental carbon in bulk aerosol particles (2.5 um), on samples collected twice daily. Physical characterization of particles included total particle counts using a CPC, number size distribution from 5-3000 nm, cloud condensation nuclei, and hygroscopic properties (Prenni et al., 2002).

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] describes specific study objectives (Li, 2004) and presents 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 and aloft measurements were taken from a Convair 580 and a Cessna 188. Selected measurement data have been compiled for each site and aircraft and are archived as site-specific data sets.

Data files are in the NARSTO Data Exchange Standard (DES) format that is described in detail on the NARSTO Quality Systems Science Center (QSSC) web site. The files follow a tabular layout and are stored as ASCII comma-separated values files (.csv). The DES does not rely on row position to identify specific information, but uses a tag to describe the information contained in the row. The DES is a self-documenting format with three main sections: the header contains information about the contents of the file and the data originator; the middle section contains metadata tables that describe/define sites, flags, and other codified fields; and the final section is the main data table that contains key sampling and analysis information and the data values. Descriptions of the standardized metadata fields are also available on the QSSC web site.
