Abstract :
The development and evaluation of a seasonal air quality model for ozone by the Community Multiscale Air Quality (CMAQ) model for the summer of 2001 in the Great Lakes in this paper are described. The CMAQ simulated ozone and the Air Quality System (AQS) observed values are compared utilizing hourly ozone values. Normalized Mean Bias (NMB) and Normalized Mean Error (NME) as statistical metrics are used for evaluation the simulation performance. Ozone prediction performance is good, with the 5 sites for summer season having NMB values within ±15% and NME values less than 35%. The model tends to underestimate ozone concentration with average NMB -11.65%. Simulation results reflect the relationship between O3 formation and its precursors well.
