Central California Ozone Study (CCOS) - Desert Research Institute

CCOS Field Operations Plan Version 2: 5/31/00
and specifications for systems and performance audits. As part of the PQMP development
process, the QA manager will finalize the CCOS audit plan. This will include identifying quality
auditing needs and resources, and establishing priorities and determining which sites require
external systems and/or performance audits. Also at this time, audit procedures will be reviewed
and further developed as required.
Task 3: Conduct systems and performance audits. The QA manager will coordinate the
activities of the QA team, and schedule system and performance audits. He will be responsible
for monitoring the results of the audits and laboratory comparisons, and providing appropriate
follow-up. Audits will be required for following measurement categories.
Audits performed or arranged by Parsons Engineering
• CCOS upper-air meteorological measurements.
• Continuous HCHO analyzers at CCOS supplemental S2 and research monitoring sites.
• CO, CO2, aethalometer, nephelometers, and particulate nitrate at CCOS research
monitoring sites.
• Audits of any sites not audited by the ARB due to scheduling limitations (see below for
intended ARB auditing responsibilities).
Audits performed by ARB and BAAQMD QA staff
• Ozone, NO/NOx, and meteorological measurements at existing District and ARB
monitoring stations.
• Ozone, NO/NOx and NO/NOy, NOy/NOy*, NO2 at CCOS supplemental monitoring
sites.
• PAMS VOC measurements by ARB and supplemental hydrocarbon measurements by
DRI, OGI, and the Bay Area AQMD and supplemental carbonyl measurements by
AtmAA, and the Bay Area AQMD). Audit consists of a through-the-probe audit using a
25-component standard hydrocarbon mixture.
• Ozone and NO/NOy on up to six instrumented aircraft.
