Preliminary 2002 PM Modeling Performance Evaluation using CMAQ and CAMx Ralph Morris, Bonyoung Koo, & Bo Wang ENVIRON International Corporation Joint Workgroup Meeting St. Louis 8-Hour Ozone and PM2.5 Study St. Louis, Missouri September 26, 2006
Preliminary St. Louis PM2.5 Modeling • CMAQ and CAMx Photochemical Grid Models • IEPA lead and performed CAMx modeling • MDNR lead on CMAQ modeling • Q1 & Q2 performed on CENRAP computers; Q3 at MDNR and Q4 at ENVIRON • ENVIRON able to get MPI multi-processing to work with CMAQ on CENRAP computers • 36/12 km grid: • “Smaller” and “Larger” 12 km grid being evaluated • IEPA CAMx run performed on “smaller” grid • CMAQ run performed on “larger” grid • Annual 2002 36/12 km SMOKE emissions modeling • ENVIRON on-road mobile and biogenics SMOKE • MDNR Point, Area and Non-Road SMOKE
St. Louis 36 km (Domain 1) and “Larger” (Domain 2) and “Smaller” (Domain 3) 12 km Modeling Domains for 2002 Annual PM2.5 Modeling using CMAQ and CAMx
Preliminary St. Louis PM2.5 Modeling • Boundary Conditions for 36 km Domain • Based on CENRAP 2002 Typical Base B CMAQ simulation • MM5 36/12 Meteorology • Joint effort of MDNR, IEPA, Ameren, and ODEQ • Independent model evaluation by ENVIRON for CENRAP • http://pah.cert.ucr.edu/aqm/cenrap/ppt_files/CENRAP_VISTAS_WRAP_2002_36km_MM5_eval.ppt • PM Model Performance Evaluation • ENVIRON received CAMx inputs and outputs from IEPA; & CMAQ Q1 & Q2 from CENRAP • CMAQ Q1 & Q2 received Sep 19 – little time for evaluation
Preliminary PM Model Evaluation • Local/ Urban Evaluation in St. Louis Region • 16 FRM PM2.5 Mass Monitors • 1-2 STN PM2.5 speciation Monitors • Regional Evaluation in Smaller 12 km Grid • 10 IMPROVE PM2.5 Speciation Sites • 11 CASTNet Weeked PM2.5 Speciation Sites • 257 FRM PM2.5 Mass Sites • 5 NADP Wet Dep Sites
St. Louis PM Model Evaluation Domain 16 FRM PM 2.5 Mass Sites 1-3 STN PM 2.5 speciation sites
