  2. What We’ll Be Running: The Weather Research and Forecasting model with Chemistry (WRF-Chem) Version 3.4 (Release Date: April 2012) Fully coupled, “online”, state-of-the-art weather/chemistry model

  3. Horizontal Domains: (tentatively) 45 km 15 km

  4. Vertical Domains: • ~70 terrain-following sigma levels • Packed in the boundary layer and near the tropopause • Model top of 10 hPa TTL ~1 km

  5. Met Initial and Boundary Conditions • Global Forecast System (GFS) 0.5°x0.5° real-time data • 3 hourly time intervals

  6. Chem Initial and Boundary Conditions • MOZART-4 • CO is assimilated with MOPITT CO retrievals • Also uses GFS meteorology • RACM chemical mechanism • MEGAN biogenics • Biomass burning emissions from MODIS • Anthropogenic emissions from RETRO • GOCART aerosol parameterization

  7. MET Products: • “Standard” variables at multiple pressure levels • Simulated radar reflectivity • Convective fields (convective precip, etc.) • Thermodynamic Diagrams Sim. Radar Reflectivity Total 24 h Precip

  8. Simulated Reflectivity

  9. CHEM Products: CO O3 NO NO2 CH4 SO2 Surface CO 200 hPa Ozone

  10. Surface CO & 10 m Winds
