An investigation into seasonal and regional aerosol characteristics in East Asia using model-predicted and remotely-sensed aerosol properties [PDF]

Atmospheric Chemistry and Physics, 2008
In this study, the spatio-temporal and seasonal distributions of EOS/Terra Moderate Resolution Imaging Spectroradiometer (MODIS)-derived aerosol optical depth (AOD) over East Asia were analyzed in conjunction with US EPA Models-3/CMAQ v4.3 modeling.

Comparing CMAQ Forecasts with a Neural Network Forecast Model for PM2.5 in New York

Atmosphere, 2017
Human health is strongly affected by the concentration of fine particulate matter (PM2.5). The need to forecast unhealthy conditions has driven the development of Chemical Transport Models such as Community Multi-Scale Air Quality (CMAQ).

AIR POLLUTION DIFFERENCES IN SIMULATION PATTERNS BY USING MM5-CMAQ AND WRF-CMAQ: SUMMER 2003 EUROPEAN POLLUTION EPISODE

Hrvatski meteorološki časopis, 2008
One of the most important advantages of the modern and state-of-the-art air quality modelling systems is the capability to produce air pollution forecasts and particularly for ozone. In this contribution, we have applied the CMAQ (EPA) air quality modelling system to produce ozone air quality forecasts and compare the results for the 2003 August ...

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 ...

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.
