CoHA & TSSA Notes and Overall Project Schedule

1. CoHA & TSSA NotesandOverall Project Schedule Attribution of Haze Workgroup July 23, 2004

2. Topics • Notes on CoHA and TSSA projects • Schedule for AoH and related WRAP activities

3. Notes on CoHA • Routine average statistics from CoHA are monthly, best and worst are event-specific • EDAS wind fields for contiguous region, hemispheric model for HI and AK, edges of EDAS maybe a problem • Sophisticated analyses are site-specific, build wide base to fine-tune analyses – aggregate information • Need diagram of tribal CoHA project • Best and worst days period of record on site summary in addition to average – show period of record in text on any plots • Valley-based monitoring sites – local terrain and air movement, Near 50km emissions maps weblinks • Regional impacts analysis, followed by more detailed localized/episode analysis – start with example test cases

4. Tribal Causes of Haze Assessment ProjectJuly 2004 to early 2005 • A. Perform full CoHA analysis (www.coha.dri.edu) for 5 tribal Class I areas (+ Hualapai) – prepare report, review with Class I tribes individually – based on best available data. • Descriptive material • Episode analysis • Conceptual models • perhaps Transport regression analyses • . Analyze locations of each remaining tribal lands against IMPROVE monitoring network sites for “representativeness” of monitoring data for each tribal area. • . Map all tribal lands and IMPROVE sites. • . Perform spatial analysis to group [as appropriate] tribal lands, and recommend which individual and groups of tribal lands to link to IMPROVE monitoring sites, based on professional judgment. • . Translate CoHA analyses from federal Class I area IMPROVE monitoring sites identified in #2, and link to the appropriate individual or groups of tribal lands. • . Prepare report and maps showing tribal lands and the associated IMPROVE monitoring sites. • C. For tribal lands with no “representative” IMPROVE monitoring site, recommend general locations of IMPROVE monitors to fill “holes“ in the IMPROVE network for tribal lands in the WRAP region, to support regional haze analysis. • Prepare maps of individual and groups of tribal lands that do not have “representative” IMPROVE data. • Add to a second version of the maps the recommended general locations of additional IMPROVE monitoring sites for characterizing regional haze impacts on tribal lands. • Prepare report with recommendations for additional tribal IMPROVE monitoring.

5. RMC TSSA Notes • Mesoscale vs. synoptic scale – answer may miss subregional scale • 2002 GEOS-Chem results –when will it be done? • Table capturing (pros and cons) sensitivity methods characteristics • Grid cell overlaps at state boundaries issue – SMOKE outputs as emissions density maps by source category (point, area, mobile, fire, et cetera) – overlay county boundaries on grid cells • Method for comparing monitoring and modeling data results • Uses of modeling data results for AoH workgroup and others – educators, WESTAR, ARB as resources – link to next AoH meeting

6. AoH Schedule • July 22nd – Review/discuss work products • RMC – Tagged Species Source Apportionment modeling study • DRI - CoHA descriptive results, episode analyses, examples of conceptual models and transport regression modeling analyses • August – conference call August 10th, 130 Pacific, lay out proposal for regular call schedule • Training separate – aim for 8/31 100 PM through 9/1 400 PM • September meeting 21st @ 100 PM through 500 PM on 22nd • October 13th 130 PM Pacific placeholder for conference call • December meeting? and conference call(s) • Review draft report? • January 2005 • Publish final 2004 AoH report • Make plan for subsequent workgroup activities

7. WRAP project deliverables July to December 2004 • August • 8/31- WB Dust emissions from RMC • 8/31 and 9/1 - Modeling results training by RMC • September • Early Sept. – 2002 Annual TSSA model results from RMC • 9/10 - Final actual 2002 Wx/Rx/Ag/rangeland fire EI data to RMC – associated EI report date TBD • 9/21-22 – AoH Workgroup meeting • October • EDMS on line with “final, complete” 2002 EI for WRAP region • Early October – conceptual models

8. WRAP project deliverables July to December 2004, continued • November • Early Nov. - Natural/Anthropogenic TSSA results by state level apportionment • Cutoff date for technical work products from RMC, CoHA, EIs, and other technical data providers • Additional CoHA deliverables • Policy summary of the 3 [2002-04] NSF Organic Aerosols Workshop series [what did the academic researchers say they know and don’t know well enough to act on] • Project status for November WRAP Board Meeting • December • Draft AoH report delivered • Distribute draft report and collect comments within WRAP organization, state/tribal/FLM agencies – maybe parallel peer review? • January 2005 – AoH Phase 1 finish

9. CoHA Next Steps • Choices for CoHA • 1)      Go ahead with qualitative conceptual analyses - /04 • 2)      Go ahead with transport regression, no conceptual model work - /04 • 3)      Do transport regression work and integrate into conceptual models - /05
