  1. Midwest RPO Update:Air Quality and Meteorological Modeling Kirk Baker November 2003 National RPO Technical Meeting

  2. The Last 12 Months • Ran CMAQ, REMSAD, and CAMx4 for a summer and winter episode • 36 and 12 km simulation for summer episode with CAMx4 • 36/12 and 4 km flexi-nests for summer 2001 episode with CAMx4 • Initial wet deposition analysis • Aircraft measurement comparisons for summer episode (just O3, NO, and NO2) • Ran MM5 for 2002 at 36 km Midwest Regional Planning Organization

  3. The Last 12 Months • Model performance: identification of model deficiencies and inventory issues • Sensitivity runs for summer 2001 episode to assist in understanding model performance problems • Ran preliminary sensitivity runs at 36 km for summer and winter episode—technology transfer to States and cooperating organizations • Ran CAMx4 for 2002 at 36 km with 1999 anthropogenic emissions Midwest Regional Planning Organization

  4. The Next 12 Months • Monthly model performance analysis for 2002 CAMx4 simulation • Larger-scale wet deposition analysis • Sensitivity run project: 36 and 12km global and geographic emission reductions • Implement new science into CAMx4: PSAT and aerosol PIG Midwest Regional Planning Organization

  5. The Next 12 Months • Begin statistical analysis of model output • Initial regulatory basecase modeling • Alternative annual simulations (annual sensitivity runs) • Evaluate 2002 output against special studies and operational Super Sites • Continue to re-run the core episodes as emissions inventory/modeling improves Midwest Regional Planning Organization
