Air quality modeling and uncertainty Sample Clauses

Air quality modeling and uncertainty. To estimate health outcomes, we explored the potential impacts of emissions on the formation of PM2.5 and O3 concentrations. We used the Weather Research and Forecasting model with Chemistry (WRF-Chem) to simulate air quality. Chemical reactions in the atmosphere and meteorology both affect the formation of air pollutants. As suggested by Xxxxxx (2000), we used a model that couples meteorology and chemistry. However, model simulation is not a cure-all solution. The model prediction results are influenced by both emission scenarios and meteorological factors (Akimoto, 2003). Emission inventory inputs for generating current and future air quality have been discerned as the most pressing factor for describing future air quality issues (Lin et al., 2005). Emissions in Asia are especially not well understood. Studies have been done to compare emission inventories for Asia and found large discrepancies (Saikawa et al.
