Today’s Presentation
• Recap recommendations from last call• Describe latest CAMx simulation
– Use of PSAT on the August 2004 Base Year scenario
• Next Steps

Recap
• Recommendations from last call:– Focus on August episode
• Run 2018 Case• Run PSAT for 2004• Run 5 “What-if” scenarios for 2018• Use model trends in relative sense to scale
IMPROVE observations– Relegate November episode
• Revisit with possible follow-on funding?

PM Source Apportionment Technology
• What is PSAT?– Emissions of PM and gas precursors are
stratified by source category and by source region
– Tracers are used to tag emissions from each category-region pair and to track their transport, chemical evolution, and fate
V:\corporate\marketing\overview.ppt
PM Source Apportionment Technology
– Tracers are run for species groups:• Sulfur (SO2 and PSO4)• Nitrogen (NOx, NOy, nitric acid, ammonia,
PNO3, and PNH4)• Organics (VOC, condensable hydrocarbon
products, and SOA components)• Primary PM (carbonaceous, fine/coarse dust,
and fine/coarse other PM)
V:\corporate\marketing\overview.ppt
PSAT for August 2004 Base Case
• Quantify source attribution at Mt Zion and Wishram
• 12 source categories by 6 source regions– 10 source categories + IC + BC– Region 6 handles all emissions outside the 4-km
grid
• Sulfur, nitrogen, and primary PM groups• Organics: let core model report biogenic vs.
anthropogenic apportionment

PSAT for August 2004 Base Case
• Source categories:– On-road mobile sources– Non-road mobile sources– Ammonia sources– Other area sources– Electric generating units (EGU)– Pulp mills– Wildfires– Other fires– Other point sources– All emissions outside the 4-km grid
V:\corporate\marketing\overview.ppt
PSAT for August 2004 Base Case
• 6x10 category/region matrix + IC/BC = 62 unique tracers
• Sulfur (2 species), Nitrogen (7 species), primary PM (6 species) for each tracer– Total = 930 total tracers in PSAT
• To “fit” the model into memory:– Run only the 4- and 12-km grids
• 36-km grid results used to extract 12-km BC’s– 10-day spin-up was not run for PSAT
• 12-km 3-D concentration fields on August 10 used as IC’s
V:\corporate\marketing\overview.ppt
PSAT for August 2004 Base Case
• PSAT results were post-processed for two monitoring sites along the Columbia River:– Mt Zion, and Wishram– Report results for the episode-average source
apportionment (August 10-22)– Tables presented for “top” ranked emission
category-region pairings• Represent 90%+ mass concentrations for each
species
