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
MC2 to MM5 4-km MM5 3.3-km MC2 Interpolation between projections and grid resolutions
MC2 to MM5 Mapping Time Invariant & Time Variant param’s from MC2 to MM5
MC2 to MM5 Conversion performance & evaluation
Parallel CMAQ Performance CPU time elapsed (seconds), and Percent (%) time relative to a single-CPU run.
Vancouver Ozone (ppbV) CMAQ Model Performance PM2.5 (µg/m3)
Ozone (ppbV) Chilliwack CMAQ Model Performance PM2.5 (µg/m3)
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
On-Road Vehicle Surrogates & Temporal Profiles Spatial Surrogate Techniques a) Road length b) VMT (traffic demand model)
