Air Quality Analyses for Photochemical Smog Associated with Atmospheric Aerosol Particles and Ozone Precursors Using CMAQ and CAMx Modeling Systems (original) (raw)
Atmospheric Chemistry and Physics
Through the comparison of several regional-scale chemistry transport modeling systems that simulate meteorology and air quality over the European and North American continents, this study aims at (i) apportioning error to the responsible processes using timescale analysis, (ii) helping to detect causes of model error, and (iii) identifying the processes and temporal scales most urgently requiring dedicated investigations. <br><br> The analysis is conducted within the framework of the third phase of the Air Quality Model Evaluation International Initiative (AQMEII) and tackles model performance gauging through measurement-to-model comparison, error decomposition, and time series analysis of the models biases for several fields (ozone, CO, SO<sub>2</sub>, NO, NO<sub>2</sub>, PM<sub>10</sub>, PM<sub>2. 5</sub>, wind speed, and temperature). The operational metrics (magnitude of the error, sign of the bias, associativity) prov...
