NARSTO PAC2001 NRC-IAR Convair 580 Particle Count, Ozone, Meteorological Data |
The main mission for the National Research Council - Institute for Aerospace Research (NRC-IAR) Convair 580 was to map the particle spatial distribution in the valley through remote sensing, and to provide critical meteorological data, particle number size distribution and O3 profiles. Only the latter set of measurements are being archived at this time.
The flights followed mostly meridional and two approximately east-west tracks at 4800 m over the valley for remote sensing using two LIDARs (Strapp and Chevrier, 2001). Spirals from 150-6000 m, for vertical profiles of O3, particle number size distribution, and meteorological parameters, were conducted at the model western boundary at 49° 20' N and 123° 45' W, at the model southern boundary of 48° 25' N and 123° W, as well as during takeoff and landing. A typical flight covered the valley in eight meridional legs, approximately equally spaced, with three of them directly over the ground sites Slocan Park (SP), Langley Ecole Lochiel (LEL), and Sumas Eagle Ridge (SER). East-west flight tracks were flown north and south of the Fraser River, covering most of the urban centers of the valley to probe the urban-suburban-rural gradient, with additional E-W tracks over the north shore lakes to help understand the valley flow situation.
The remote sensing was based on aerosol backscattering using upward- and downward-looking LIDARs at the 1064 nm wavelength with a depolarization channel (Strawbridge and Snyder, 2004a). The profiles were obtained during aircraft spirals, specifically located at the western and southern boundaries of the domains of air quality models UAM/V and Model 3/CMAQ, and were intended as the input as boundary conditions for further modeling. The Convair mission flights covered an area with boundaries roughly corresponding to the model domain of Model 3/CMAQ application to the region, with the eastern boundary at 121° 52' 30" W and the western boundary at 123° 50' 13" W, and extended from 48° 30' N to 49° 30' N over the mountain tops.
On August 26th and 29th, night missions were flown from approximately 9 p.m. to 2 a.m. the next morning, primarily to map the nighttime movement of the urban plume in the main and secondary valleys (Strawbridge and Snyder, 2004b). The ground site overflights provided an assessment of the vertical thermal structure and the extent of particle spatial distribution over the sites.
The Pacific 2001 Air Quality Study 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. 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.
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.

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.
Pacific 2000 data file names are comprised of nine sections, defined as follows:
