Central California Ozone Study (CCOS) - Desert Research Institute

CCOS Field Operations Plan (DRAFT) Version 2: 5/31/00
Aerosol Dynamics (AD) will acceptance test the particulate nitrate analyzers under an
existing contract for CRPAQS. AD will also assist DRI with the installation and initial
calibration of instrument at the Sunol research site.
2.4.4 Facilities Installation
ENSR will be responsible for site preparation for the Central California Ozone Study.
Four sites will be newly established for CCOS (McKittrick, Kettleman City, Piedras Blancas,
Granite Bay, Altamont, Lambie Road, Bella Vista). In addition, several existing sites will be
modified as necessary to accommodate CCOS measurements (Bethel Island, Bodega Bay,
Pacheco Pass, Trimmer, and Sunol).
ENSR will make final arrangements with landowners to use their land for CCOS, and
establish a written lease agreement. Establish written lease agreements or land use agreements,
as necessary. Security fencing and trailer will be installed and electrical and phone service will
be arranged. They will oversee the installation of facilities at each site, and travel to sites, as
necessary, to direct the operations of contractors and to ensure that all facilities are placed
properly.
2.4.5 Equipment Installation and Calibrations
Installation will be performed by DRI and CE-CERT and will be coordinated between the
two groups so as to be at common sites at overlapping times. This will allow the placement of
the instrumentation to be made for mutual advantage. It should also allow those site operators
that will require training to effectively plan their schedules to limit the amount of time needed for
training.
DRI will install the O 3 analyzers, CO analyzers, CO 2 analyzers, calibration systems, data
loggers (at S0, S1, and S2 sites), CRPAQS DAS (at research sites), diode array spectrometers for
actinic flux measurements, particulate nitrate analyzers, Aethalometers, and nephelometers. Full
onsite calibrations will be performed on the O 3 , NO/NOx, CO, CO 2 analyzers, particulate nitrate
analyzers and the nephelometers. The diode array spectrometers will be calibrated in Reno
before installation and onsite with a field lamp. Data loggers will be installed, instruments
connected, and data collection confirmed at the site and at DRI’s central computer in Reno. The
data connections will also include those instruments that CE-CERT will install. Any connections
of existing site instruments to the data loggers will be made. At those existing sites where a site
calibrator is expected to supply NO and NO 2 (Bruceville, Turlock, Bethel Island, and Arvin),
those connections will be made such that the current site operations are not adversely affected.
The site operators will be trained in the operations of the supplemental instruments. Each
measurement will have a standard operating procedure that lists the specific tasks required of the
site operator. They will also contain information on procedure for handling problems and
personnel to contact for assistance.
CE-CERT will install the NO/NOx analyzers, NO/NOy, NOy/NOy*, and HCHO
analyzers at S2 and R sites as part of this contract and the NO 2 /PacN analyzers. Full calibrations
will be done for each analyzer. This will include NO, NO 2 , nitric acid, and n-propyl nitrate
(NPN) for the NO/NOy and NOy/NOy* analyzers, HCHO for the HCHO analyzers, and NO 2
