Attribution of Haze Project Update

This document provides a comprehensive update on the Attribution of Haze Project, focusing on fire emissions discussed during the Joint Forum Meeting held on September 8-9, 2004, in Worley, ID. Presentations covered project timelines, Class I areas for attribution, emissions data, and source apportionment modeling parameters. Key activities included discussions on interim emissions inventories, source apportionment results by state, and ongoing report drafting. The meeting emphasized collaboration for upcoming AoH events and the development of final reports and summary products.

Presentation Transcript

  1. Attribution of Haze Project Update Fire Emissions Joint Forum Meeting September 8-9, 2004 Worley, ID

  2. Attribution of Haze Project Update • Today’s presentation • Schedule status • Class I areas for attribution • Support contractor/web page • Emissions data displays examples • Source apportionment modeling parameters • Transport regression approach

  3. 2004 AoH Project Schedule - Status • 9/20-21 – Uses of Modeling Results training • 9/21-22 – AoH meeting (both in Salt Lake City) • “Interim” emissions inventories displays/qualifiers • Source apportionment modeling results for each Class I area by State and key species • Detailed draft outline of project report • 10/8 and every 2 weeks – conference call • Week of 11/15 – AoH and Dust Emissions Forum meetings/Causes of Haze tools training – Las Vegas • CoHA “transport regression” results for source regions • Natural/manmade source apportionment results for each Class I area • Continuing drafting or report • External review draft report December 2004 • Complete report by January 2005

  4. AoH Phase I Web Page Operational • Go to the AoH Work Group “About” page and click on the “Phase I (ARS)” link under “Projects” in the right hand navigation box • Or, go directly to this link: http://www.wrapair.org/forums/aoh/ars1/index.html • This page contains a brief overview of the project and direct links to ARS presentations • The “Report” section of the navigation box will direct you to other ARS documents – currently, only the “EI Summary Products” link is active

  5. Review of 2002 “interim” Emissions • Fires • Actual 2002 wildland fire and prescribed fire emission inventories • Specific location, date, size and fuel loading for each fire event. • Biogenic Emissions • Biogenic Emissions Inventory System (BEIS3) • Vegetation Data: Biogenic Emissions Landuse Database (BELD3) • Meteorological Data (MM5v3)

  6. Next Steps • Review modeling and monitoring results • Work with RMC to determine best way to summarize boundary conditions and off-shore emissions • Prepare a simple comparison between “actual” and “interim” 2002 EI • Develop outline for final report • Generate summary products for Class I areas/clusters • Updates will be presented at AoH meeting in Salt Lake City (Sept. 20-22)

  7. Tagging Priorities for “2002-like” EIs (State/Source Category/Species) for Geographic Source Apportionment Modeling Study (6/04)
