1. Models-3 Users’ Workshop Raleigh, North Carolina October 27-23, 2003 New Developments and Applications of Models-3 in Canada J. Wayne Boulton*, Mike Lepage, Xin Qiu, and Martin Gauthier RWDI West Inc., Guelph, Ontario, Canada Colin di Cenzo Environment Canada P&YR, Vancouver, British Columbia, Canada

2. New Developments MC2 to MM5 converter  Convert MC2 output for input to SMOKE & CMAQ  Re-project and interpolate horizontal grids  Convert vertical grid to MM5 sigma levels  Map different parameters between MC2 and MM5 Parallel processor CMAQ runs on LINUX  Compile CMAQ (source + libraries) to run in parallel distributed LINUX environment (with UC Riverside) Real-time AQ forecasting (MC2, SMOKE, CMAQ)  Assist University of B.C. staff to setup of real-time 12-km & 4-km regional AQ forecasts for the PNW

3. PNW Model Domains

4. MC2 to MM5 Interpolation between projections and grid resolutions 4-km MM5 3.3-km MC2

5. MC2 to MM5 Mapping Time Invariant & Time Variant param’s from MC2 to MM5

6. MC2 to MM5 Conversion performance & evaluation

7. Parallel CMAQ Performance CPU time elapsed (seconds), and Percent (%) time relative to a single-CPU run.

11. Ozone (ppbV) PM 2.5 (µg/m 3 ) CMAQ Model Performance Chilliwack

12. New Applications CMAQ runs in support of Health Canada risk assessments  75% electric vehicle fleet penetration with four electricity production scenarios  GIS-based post-processing routines developed  Ethanol blend fuel (E10) scenarios (ongoing) CMAQ runs in support of emission source contribution assessments from power plants  Various emission / source contribution scenarios  Hourly power plant emissions modelled in SMOKE Development of improved spatial surrogates and temporal profiles for SMOKE  Based on traffic demand model (EMME/2) outputs

13. On-Road Vehicle Surrogates & Temporal Profiles Spatial Surrogate Techniques a) Road length b) VMT (traffic demand model)
