Quantifying the Impact of Multiple Factors on Air Quality Model Simulation Biases Using Machine Learning

Atmosphere
Accurate air pollutant prediction is essential for addressing environmental and public health concerns. Air quality models like WRF-CMAQ provide simulations, but often show significant errors compared to observed concentrations.

Intercontinental and Regional Modeling of Air Pollutants Transport over the Pacific Regions

, 2006
Fine particulate (PM2.5) continues to be a major air pollution problem due to its adverse effects on human health and the environment. Recently, the rapid industrialization now taking place in Asia is producing a large and growing quantity of NOX, SO2 ...

PAMS-constrained top-down calibration of VOC-speciated CMAQ simulations

Atmospheric Chemistry and Physics
Abstract. Accurate simulation of volatile organic compounds (VOCs) remains a persistent challenge in chemical transport models (CTMs), limiting their ability to diagnose species-specific emissions and their role in ozone (O3) formation. Most models rely on lumped surrogate species, which limits their ability to represent speciated VOCs and directly ...
