  1. WRAP Workshop on Fire, Carbon, & DustEmissions of Carbon from Fire Fire Emissions Joint Forum Presented by – Dave Randall, Air Sciences Inc. May 23, 2006 Sacramento, CA

  2. From Acres to Extinction

  3. FIRE INVENTORY USE July 1996 WF (prototype) >Establish EI method 1996 WF >Model performance Initial projection EI’s >Model performance; 2018: Rx, Ag initial attribution analysis Typical: WF 2002 QC’d EI>Model performance; WF, Rx, Ag, NFR attribution; sensitivity; NEI Planning EIs – all types>Attribution; Baseline (2000-2004) SIP Preparation Projection (2018) STATUS complete complete complete complete complete in progress (07/06) How Fire EI’s Have Been Used

  4. EC Emission SummaryWRAP-wide (w/o AK) All Fire Types (max scale 80,000 tons)

  5. OC Emission SummaryWRAP-wide (w/o AK) All Fire Types (max scale 600,000 tons) 7x EC

  6. Spatial Distribution Baseline WF and RX

  7. Temporal Distribution: Baseline Wildfire EI

  8. Temporal Distribution: Baseline Rx Fire EI

  9. Five things you should know about the WRAP’s Fire EIs: Planning EIs (Ph III/IV) are nominal (possible). Greatest uncertainty is in fuel loading and consumption (+/- 50% or more). Emission factor information is fair (very sparse for pollutant speciation). Plume characteristics – we use anecdotal information to generalize (getting better). Even small fires in the EI, proximate to a Class I area, appear to show up as modeled visibility impacts. Uncertainty and Accuracy in Fire Emissions

  10. Baseline Annual PM2.5 Emissions by County Case Study Area: Sawtooth Wilderness
