  2. Regional Emissions

  4. 2003 Banff Burns • PM sampling in smoke from prescribed burns • Analyzed PM for Elements, Ions and PAHs • Followed up with lab micro-burns controlled for • Fuel • Temperature and character of combustion • Oxygen • Low Oxygen, modest fire temp; generated highest Retene levels

  5. 2004 Fire work • Planned burns disrupted due to weather • Research ongoing for using multi-axis photos. • Assess fire spread rates • Assess plume rise characteristics • Assess plume volume • Assembled portable package for PM2.5, CO, CO2, Temp and windspeed • Anticipate spring burns (post April)

  6. PM work in Saskatchewan • Funding allocated to study PM ($20K) • Contract process underway • Evaluate Boundary Dam area • Use surrounding area for context • Northern States • Bratts etc. • GDAD application to PM also funded. • Contract Issued

  7. Prairie PM2.5 climatology • Summary report underway • Seasonal variations • Regional characteristics • Alberta, Saskatchewan and Manitoba • Few stations in SK and MB • Record too short for trends

  8. Modelling Projects Episodic Runs • Sensitivity of O3 Predictions to Uncertainties in Biogenic Emissions (tree speciation) • Model Evaluation (aircraft measurements) • Source Sector Analysis and Control Scenarios Annual Model Runs (2002 & 1999) • Transboundary Transport – CAN/US, Provincial • Sulphur and Nitrogen Budgets • Acid Deposition • Future Emission Scenarios

  9. MM5/CMAQ Annual Runs • 36 km grid most of N. America: • Complete • First 12km NWT; • Complete this week • More 12 km and 4 km areas planned • 1999 not started

  10. CMAQ Modelling Domains Coarse Domain 36km Northern Domain 12km 12km Oil Sands 4km 4km Edm-Calg AB-SK Domain

  11. Support Projects (Emissions) • 4km Area and Mobile Emissions • Agricultural Emissions • Northern Emissions • Projected emissions for year 2010 • Improving Biogenic Emissions by using the Canadian National Forest Inventory

  12. Prairie2005 • Overall aim is address budgets of PM and Ozone in Prairies • Focus on fluxes in and out of Alberta • Modeled • Measured • Additional measurements will evaluate • Model performance • Capability of current monitoring network • Three dimensional nature of AQ

  13. Air-Quality Models • CHRONOS (MSC): 21 km horizontal resolution North American forecast of O3, bulk speciated PM2.5 and PM10. 48 hour forecasts. • AURAMS (MSC): 21 km horizontal resolution Western Canada forecast of O3, size and composition resolved PM and precursors. 48 hour forecasts. Higher resolution runs in post-measurement campaign, non-forecast mode. • CMAQ (US EPA, used by MSC-PNR): Western Canada simulations of O3, size and composition resolved PM and precursors. 36, 12, 4 km runs (by PNR) in post-measurement campaign, non-forecast mode.

  14. Mobile Platforms (1): Ground Based • MSC CRUISER: Continuous (< 15 minute) measurements of CO, NO, NOy/NOx, SO2, O3, VOCs, black carbon, PM mass, ultrafine particle counts, 30 – 1000 nm particle size and composition. • MSC RASCAL: scanning lidar: particle scattering/absorption, boundary layer structure. • AENV MAML(Mobile Air Monitoring Laboratory): continuous O3, CO, NOx, NH3, SO2, H2S, THC, PAHs, TSP, PM10, PM2.5. • All three also measure meteorology (wind direction and speed, temperature, RH). • MAML and CRUISER overlap some measurements – could be deployed in different locations at the same time.

  15. Mobile Platforms (2): Aircraft Based Cessna 207 + Cessna 188 Tandem Flights • Two aircraft flying in tandem along same trajectory. • Cessna 188 “crop-duster”: payload: Hg, O3, condensation nucleus counter, particle sizes (CPSP and FFSP), filters, VOC canisters, NOx, meteorology package • Cessna 207: two payloads, swapped half-way during the study. Meteorology package +… • Particle size and composition (AMS) + SO2 monitor. • Downward LIDAR.

  16. Objectives P2005 • During 04/05 • Set up the aircraft • Set up logistics • Finalize science and project plan • Coordinate Partners • 05/06 • Conduct the experiment • Collate and distribute data • Start writeup • Determine appropriate follow-up

  17. Regional AQPP • Operational AQI forecast started in May • AQPP scientist hired on term • Pursuing second scientist for program • Over the winter • Establish collection remaining AQ obs in real time: SK and MB • Generate forest fire smoke guidance tools • Beyond: • Develop alternative forecast methods including statistical methods • Outreach

  18. CORE and Acid Rain • 30K last year and this for upgrades at Bratts. • Bought Hg calibrator and scale last year • Site upgrades this year and TBD • Lots of acid rain committee work • Likely some acid applications to annual model runs.

  19. EA work and the North • Oil Sands continues to expand • Upgrader proposed NE of Edmonton • Diamond Mining continues • Mackenzie Valley Pipeline looms • Building monitoring program with RWED. • O3 and NOx monitors at Inuvik.
