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: 45 km 15 km (tentatively)

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

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