  1. Attribution of Haze Phase 2 and Technical Support SystemProject UpdateDust Emissions Joint Forums – Tempe, AZNovember 16, 2005

  2. Overview • AoH Phase 2/TSS work plan http://wrapair.org/forums/aoh/meetings/050817c/AoH_PhaseII_Work_plan_draft_081705.pdf • Review of data summary products and suggested modifications for Phase 2 • IWG input from August meeting • AoH workgroup discussion from September 14-15 • TSS scoping study • Weight of evidence approach • Critical milestones • Example graphics

  3. Goals of the AoH Phase 2 Analysis • Refine Phase 1 techniques for use in Phase 2. • Reduce uncertainty and address the remaining uncertainty in modeled data and attribution results. • Analyze the differences between modeled results for 2002 and the projected 2018 base case and various other control strategy scenarios. • Develop additional analytical approaches (e.g., receptor modeling, trends analysis, determination of the representativeness of baseline data set).

  4. Goals of the AoH Phase 2 TSS Project • Provide a single web-based location for access and display of technical data, display of analytical results, and the reference location for related documentation to support the regional haze implementation plans. • Provide specific analysis tools to synthesize technical and contextual data and GIS layers, conduct analyses, and store results for subregional/local/Class I area-specific regional haze planning. • Provide the analysis and display tools for Phase 2 analyses, and the technical support documentation for WRAP region SIPs and TIPs for regional haze.

  5. Team Members and Responsibilities

  6. Work Plan Tasks – Analysis Project • Task 1: Solicit and define user requirements from the appropriate WRAP work groups. • Task 2: Prepare suite of data products based on final 2002 emissions, modeling, and attribution results. • Task 3: Define the weight of evidence (WOE) approach to be applied to AoH Phase 2 data. • Task 4: Interpret 2018 results and implications for showing progress under the Regional Haze Rule. • Task 5: Prepare draft and final AoH Phase 2 analysis report. • (Task 11: Travel to provide progress reports and solicit project feedback at WRAP meetings.)

  7. Work Plan Tasks – TSS Project • Task 6: Perform TSS requirements analysis and scoping study. • Task 7a: Acquire and prepare the relevant databases. • Task 7b: Summarize and evaluate WRAP Dust inventory. • Task 8: Develop data review interfaces based on user requirements. • Task 9: Develop data exchange protocols and guidelines. • Task 10: Develop method to capture on-line user feedback. • Task 11: Travel to provide progress reports and solicit project feedback at WRAP meetings.

  8. Project Timing by Task

  9. TSS Data Summary Products • Emissions, monitoring, modeling, and attribution results will be housed in on-line databases • User requests will combine data with contextual information and/or GIS layers (if appropriate) • ARS and AoH work group will develop a Weight of Evidence (WOE) approach for integrating results • Scoping study (Task 6) will determine the level of sophistication achievable for data products during project • All data used for 2007 SIPS/TIPS will be version controlled to keep it separate from new data and information added to the TSS over time

  10. IWG SIP Outline • Revised SIP outline developed at August 29-30 meeting • Items in red are directly supportable by TSS and are required products of TSS • Each of these items exists from Phase 1 or is planned for the TSS

  11. IWG Flow Chart #1

  12. WRAP evaluation of 2018 baseline and alternative control measures. Establish reasonable progress goals based on all control measures to be implemented. State evaluates and selects alternative control measures based on the four factors. Do reasonable progress goals achieve the Uniform Rate of Progress? YES NO Consult with other States and FLMs on selected reasonable progress goals. Explain why it is not reasonable to achieve the Uniform Rate of Progress by 2018. IWG Flow Chart #2 2018 Control Strategy Evaluation Process

  13. Highlights of AoH 9/14-15 Meeting (1):TSS Scoping Study Schedule • Scoping study (task 6) must be completed before most of the remaining TSS tasks (7-10) can be started • Expected completion: November 2005 • AoH work group will receive a detailed update at November meeting

  14. Highlights of AoH 9/14-15 Meeting (2):AoH Feedback on TSS • TSS should include emissions data from EDMS and SMOKE • Attribution map products should show “footprint” of a state’s impact (essentially an isopleth map of particulate mass/extinction/dv impact for each state) • Discussion of necessity to link TSS products to the Implementation Work Group SIP outline/template • Request for some sort of TSS/WOE tutorial

  15. Highlights of AoH 9/14-15 Meeting (3):Upcoming AoH Calls/Meetings • Meeting: November 16-17 (Tempe, AZ) • Present Scoping Study update (should be near completion) • Present strawman WOE approach • Meeting: November 16-17 (Tempe, AZ) • Call: December 13 @ 2:30 MDT) • Meeting: January 24-26 (San Diego, CA) • Present beta version of TSS

  16. TSS Scoping Study Outline • Identify, understand, and refine the user/system requirements • Match products types with user needs (e.g., SIP outline) • Identify a set of case studies that illustrate the system’s use • Explore the architectural options • Select and evaluate a candidate architecture (feasibility, available expertise) • Revisit system requirements – changes needed? • Finalize selection: create set of documents and diagrams that describe system architecture, team member roles • Generate a detailed project plan • What is feasible with available time/funds? • What cannot be done at this time? • Minimum requirement: MUST support SIP preparation

  17. TSS Scoping Study Schedule • Scoping study (task 6) must be completed before most of the remaining TSS tasks (7-10) can be started • Expected completion: November 2005 • AoH work group will receive a detailed update at November meeting

  18. Weight of Evidence Approach • Recipe for assessment of reasonable progress: • Comparison between 2000-04 baseline and 2018 base case • Review alternate methods of calculating 2000-04 baseline (exclude fire, etc.?) • Review of alternate 2018 control scenarios • Justification of why a site does or does not show reasonable progress • Checklist containing each products type: • Succinct description of what information product displays • Relative uncertainty of each product • Relative importance or weight of each product • Assessment of how well various analyses “agree”: • Do all attribution methods tend toward similar results? • Do EIs combined with back trajectory analyses support attribution results? • Do changes in EIs support reasonable rate of progress demonstration? • Prepare tutorial for users – several case studies which require somewhat different approaches

  19. Highlights of 9/14-15 AoH Meeting:Emissions Data and Modeling • Final 2002 emissions inventories available • When will these be put into EDMS? • Do we need to wait for EI data to be put into EDMS? • Attribution modeling to be done with CAMx/PSAT: • Planning to run for SO4, NO3, NH4 • May test for SOA, EC, OC, Soil, CM • 2002 modeling done by Oct 10 (?), attribution results available by Oct 31 (?)

  20. Highlights of AoH Meeting 9/14-15:Causes of Haze Project Update • Some new trends products on COHA web site (http://coha.dri.edu/web/general/tools_trendanaly.html) • PMF analysis (source apportionment) will be completed ~1 month after release of 2004 IMPROVE aerosol data • Will run PMF for groups of sites (possibly based on earlier attribution results or carbon mass) • Discussion about DRI running evaluations of EDAS met fields (details need to be resolved)

  21. Weight of Evidence Approach(from Ralph Morris – WRAP RMC) • Glide paths and modeled RPG test (EPA) • Eliminate days dominated by “natural” events in modeled RPG test (e.g., fires, dust) • 2018 projections for species dominated by anthropogenic emissions (e.g., SO4, NO3) • 2018 projections for modeled worst visibility days, worst sulfate days, etc. • Other???
