Development of a Stratospheric Module Based on the CUACE and Preliminary Application to the Global Numerical Weather Prediction Model System GRAEPES_GFS3.0

Geophysical Research Letters, Volume 52, Issue 11, 16 June 2025.
Abstract Human‐induced changes in atmospheric composition, particularly from aerosols and ozone pollution, significantly impact weather forecasting. Establishing a chemical weather model is essential to more accurately and effectively account for these effects.

The Major Role of Anthropogenic Emission Underestimation in PM2.5 Estimation Uncertainty Over the Tibetan Plateau

Geophysical Research Letters, Volume 52, Issue 9, 16 May 2025.
Abstract In recent decades, the Tibetan Plateau (TP) has experienced a notable rise in fine particulate matter (PM2.5) levels, impacting its climate and ecology. However, accurately simulating PM2.5 concentrations on the TP remains challenging. This study investigates the uncertainties in PM2.5 underestimation, including meteorological conditions, dust

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 ...

Updates to the Noah Land Surface Model in WRF‐CMAQ to Improve Simulated Meteorology, Air Quality, and Deposition

Journal of Advances in Modeling Earth Systems, 2019
Regional, state, and local environmental regulatory agencies often use Eulerian models to investigate the potential impacts on pollutant deposition and air quality from changes in land use, anthropogenic and natural emissions, and climate.

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.
