Other options include scanning in hand-drawn products and placing them in PDF format for posting on the ARB CCOS web site. 3.3 IOP Decision-Making Protocol The members of the CCOS Management Team will consist of the following individuals: Don McNerny and Andrew Ranzieri - California Air Resources Board Dave Jones - San Joaquin Valley Unified APCD Chapter 3: FORECAST PROTOCOL 3-6
CCOS Field Operations Plan Version 2: 5/31/00 Rob DeMandel - San Francisco Bay Area AQMD Bridget Tollstrup - Sacramento Municipal AQMD Technical Support Saffet Tanrikulu (ARB) – Forecast Team recommendation Eric Fujita (DRI) – Operational Status and Air Quality Data/IOP history After the forecast team reaches a consensus forecast, a recommendation will be made by the forecast team leader to the Management Team. The go/no-go decision of the management team will be posted by 0300 PDT on the ARB CCOS site and pertinent information will be placed on the voicemail of a call-in line that each CCOS field study contractor is responsible to check on a daily basis. IOP decision posted at web site: http://www.arb.ca.gov/themis/forecast_iop.doc IOP decision call-in line: 916/324-1953 The following criteria will be used to decide whether or not to conduct IOP sampling: • Forecasted meteorological conditions must be favorable for formation and accumulation of high ozone concentrations. • Forecasted ozone concentrations of 125 ppb or higher, including a “ramp-up” day before the high-ozone day. • Capture a minimum of one ozone episodes in each of the three major air basins within the - Bay Area, Sacramento Valley, and San Joaquin Valley. The location of the predicted high ozone will have less influence on the decision to call an IOP during the first ten IOP days than during the last five IOPs. • Operational readiness. • Aircraft crews require at least one day without sampling after three consecutive days of operation. A daily schedule of forecasting and decision-making is shown in Table 3.3-1. The timeline is roughly as follows. Since we would like to get a ramp-up day in the episode, i.e., start measurements one day before the high-ozone, we need a 96-hour forecast (approximately 96 hours preceding the peak ozone of the episode) for the high-ozone day, permitting a 57-hour lead time to put the sampler field crew on alert and a 63-hour lead time to put aircraft pilots on alert. Aircraft operations can be performed with a 39-hour lead time, but 63 hours are desirable for the original alert status. The 24-hour forecast will also include a confirmation of a go decision, which could otherwise be canceled at if conditions change appreciable from those forecasted, permitting the sampler field crew only 9 hours to cancel the start of sampling.
