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. Air quality monitoring data routinely collect by the Greater Vancouver Regional District (GVRD) and Canadian Air and Precipitation Monitoring Network (CAPMoN) during the sampling period of PAC2001, are included as supplemental data.

This data set contains the measurement data collected by the GVRD and CAPMoN air quality monitoring programs.

The Greater Vancouver Regional District (GVRD) monitoring network of 20 sites (GVRD, 2002b) continued operation during the Pacific 2001 field study period, with enhanced QA and QC activities. At all sites, meteorological measurements were carried out at a 5-min time resolution. At a few specially equipped sites, particle mass PM10 were measured using TEOMs. The network data complements the special study sites and form a spatial distribution of the pollutants.

The Canadian Air and Precipitation Monitoring Network (CAPMoN) is a non-urban air quality monitoring network with siting criteria designed to ensure that the measurement locations are regionally representative (not affected by local sources of air pollution). The objectives are to determine the spatial patterns and establish the temporal trends of pollutants related to acid rain, to provide for long-range transport model evaluations and effects research (aquatic, terrestrial, building materials and health), to ensure the compatibility of federal, provincial and U.S. measurements, to study atmospheric processes. Scientists involved with the measurement of atmospheric pollution in urban centres would consider most CAPMoN sites to be remote and pristine. There are currently 19 measurement sites in Canada and 1 in the U.S. The Saturna Island site in located in the PAC2001 area of interest.

For more information about CAPMoN, visit http://www.msc.ec.gc.ca/capmon/index_e.cfm.

The Saturna site is located in the Lower Fraser Valley.

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 [http://cdiac.esd.ornl.gov/programs/NARSTO/]. 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.
