  1. TSS Tools to Support SIP Requirements and WOE Analyses WRAP TSS Project Team Meeting Ft. Collins, CO March 29-31, 2006

  2. TSS tools designed to: Produce specific products required in SIPs Provide for independent investigation of TSS data sets and support an overall understanding of visibility issues, while not necessarily fitting into the SIP outline Review of product requirements: IWG SIP outline (Fall 2005) Tom Moore (TM) Technical Support System Background Document (March 2006) Sample products for discussion TSS Tools and SIP Requirements

  3. IWG SIP Outline (Fall 2005) • Items in red are/will be directly supported by the TSS • The IWG SIP Outline has been modified since Fall 2005, but these products are still required • IWG will have opportunity to comment at April 27 training

  4. TSS Background Doc – Tom Moore

  5. Regional Analysis Results • Regional overview of monitoring, modeling, and emissions data supports: • IWG: not specified, sec. 4.x • TM: bullets 5 and 8 • Regional overview of attribution results supports: • IWG: sec. 2.3.1 and 2.3.2 • TM: bullets 16 and 17 • Regional WOE analyses will support regional understanding of how emissions changes affect visibility changes

  6. Class I Area Analysis Tools (1) • Metadata Browser provides site information/maps to support: • IWG: sec. 1.2 • TM: not specified • Analysis Browser (regional and Class I area “static”) supports: • IWG: sec. 2.6.1 • TM: bullets 11, 12, 14, 15, 16, 17 • Also allows for review of model performance • Data Query Wizard supports: • User direct download of data types • Trends Tool supports: • IWG: sec. 2.6.1 (WOE analysis; e.g., sulfate/nitrate trends) • TM: bullet 15

  7. Class I Area Analysis Tools (2) • Composition Tool supports: • IWG: sec. 2.2.1, 2.2.2, 4.x (2.4 – emissions by pollutant?) • TM: bullets 1, 2, 3, 4 • Data Browser supports: • IWG: sec. 2.2.3, 4.x • TM: bullets 11, 12, 14, 15 • Offsite Resources support: • Additional contextual information, particularly in terms of GIS layers • Will be used in general understanding of visibility and emissions either regionally or locally

  8. Regional (map) displays of monitoring data summaries Long-term trends Regional Class I areas (by species) Mass/Extinction distributions (log-log scale?) Timelines for Class I areas Extinction parameters Other parameters Aerosol vs. nephelometer comparisons (where available) Monitoring Data Displays

  9. Baseline Extinction: 20% Worst Days

  10. Baseline Nitrate: 20% Worst Days

  11. Long-term Trends 8-yr Trends 16-yr Trends

  12. 16-yr decrease in Bext 8-yr decrease in SO4 Class I Area Trends, 20% Worst Days

  13. Distribution of Monitored Sulfate

  14. Distribution of Measured Nitrate

  15. Data Timelines

  16. Baseline\2004: median UNC ~ 0.04\0.006; median MDL ~ 0.07\0.01 Baseline: median UNC ~ <0.001; median MDL ~ 0.001 Chloride/Chlorine Mass Timelines

  17. Aerosol vs. Nephelometer Scattering

  18. Many Monitoring data displays will also work for Modeling data Model performance 20% worst days and average (extinction) Time series of model/monitoring data (extinction) Model response (2002 to 2018) 20% worst days and average (extinction) Change in distribution (mass) Modeling Data Displays

  19. 2002 Model Performance

  20. Hells Canyon, OR/ID 2002 IMPROVE Data 2002 Model Results

  21. 2018 -2002 Model Change

  22. Distribution of Modeled Nitrate

  23. Distribution of Modeled OM

  24. Summary charts Total for WRAP region (bar chart/table) WRAP region broken down by state (bar chart/table) Individual states (bar charts/tables) Summary maps Gridded and county level emissions Extent of map defined by user Ability to sum emissions over selected areas Emissions Data Displays

  25. Total WRAP Region SO2 and NOx Emissions (2002, 2018, and difference)

  26. Anthropogenic and Natural NOx Emissions by State (Plan02)

  27. Regional NOx Emissions – All Sources

  28. Glide slopes RHR required, by deciview Glide slopes for individual species Glide slopes for individual species with estimated source emissions Attribution results Which source regions affect each Class I area? Which Class I areas does each state impact? Determination of important source emission regions Attribution/Integrated Data Displays

  29. RHR Glide Path for Agua Tibia, CA

  30. Inter-Annual Baseline Variability (Mm-1) Baseline Measurement Uncertainty (Mm-1) Worst Day Impacts and Sources

  31. Class I Area Attribution by Source Region

  32. Contributing Source Regions Determinedby Back Trajectory Residence Times

  33. Inter-Annual Baseline Variability (Mm-1) Baseline Measurement Uncertainty (Mm-1) Worst Day Impacts and Sources

  34. Class I Area Attribution by Source Region

  35. Contributing Source Regions Determinedby Back Trajectory Residence Times

  36. Class I Area Extinction Attributed to States Sulfate/nitrate extinction at Class I areas attributed to Oregon emissions Sulfate/nitrate extinction at Class I areas attributed to Arizona emissions
