| Summary: | "On 28 September 2009, the Naches Ranger District on the Okanogan-Weatchee National Forest in south-central Washington state ignited an 800-ha prescribed fire. Later that afternoon, elevated PM 2.5 concentrations and visible smoke were reported in Yakima, Washington, about 40 km east of the burn unit. The U.S. National Weather Service forecast for the day had predicted good dispersion conditions and winds that would carry the smoke to the less populated area north of Yakima. We undertook a case study of this event to determine whether conditions leading to the intrusion of the smoke plume into Yakima could have been predicted before the burn was ignited, either from forecasts and model output available on the day of the burn or from higher resolution model output made available only after the event" -- Prelim. p. |
