The Impact of Nocturnal Boundary Layer Height on Daytime Surface Particulate Nitrate Increases by Vertical Transport From the Residual Layer

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Particulate nitrate (pNO3−) has become a critical air‐quality issue, with pronounced morning increases in surface concentrations attributed to downward transport from upper layer. However, how the nocturnal boundary layer evolution modulates this process remains unclear.

Systematic analysis of interannual and seasonal variations of model-simulated tropospheric NO₂ in Asia and comparison with GOME-satellite data [PDF]

Atmospheric Chemistry and Physics, 2007
Systematic analyses of interannual and seasonal variations of tropospheric NO2 vertical column densities (VCDs) based on GOME satellite data and the regional scale chemical transport model (CTM), Community Multi-scale Air Quality (CMAQ), are presented ...

Contrasting Mechanisms of Heatwave‐Ozone Pollution Compound Events and Independent Heatwave Events in the Yangtze River Delta

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 11, 16 June 2026.
Abstract Heat waves do not always coincide with ozone pollution, yet the mechanisms controlling their divergence remain insufficiently understood. Here, we investigate why some heat waves evolved into heatwave‐ozone pollution compound events (HWOP), whereas others remained isolated heat wave events (IHW), over the Yangtze River Delta during summer 2024.

Observation‐Constrained Fossil Fuel CO2 Emissions Reveal Post‐2018 Stabilization in China

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Accurate quantification of interannual variations in China's fossil fuel CO2 (FFCO2) emissions is critical for climate policy evaluation. However, bottom‐up inventories exhibit growing discrepancies. Here, we estimate China's 2015–2023 FFCO2 emissions using the Regional multi‐Air Pollutant Assimilation System, integrating in situ observations ...

Adapting CMAQ to investigate air pollution in North Sea coastal regions [PDF]

Environmental Modelling & Software, 2008
The Models-3 Community Multiscale Air Quality (CMAQ) model is setup on a 54x54km^2 grid for Europe and on a nested smaller domain with a 18x18km^2 grid for the North Sea region. This paper concentrates on the models ability to represent the transport and deposition of atmospheric pollution in North Sea coastal areas.

D‐DNet: A Dual Deep Neural Network Framework for High‐Efficiency Operational PM2.5 and AOD550 Forecasting With Data Assimilation

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.
Abstract Accurate forecasting of PM2.5 (particulate matter with diameter ≤2.5 μm) and AOD550 (aerosol optical depth at 550 nm) is crucial for air quality management, public health, and environmental policy. Traditional physics‐based forecasting systems, though robust, require computationally intensive simulations and data assimilation (DA) schemes that

Improving Estimates of Prescribed Fire Smoke: Insights From a Novel Southeastern US Burn Permit Geodatabase

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract The southeastern US accounts for over 60% of national prescribed (Rx) burning acreage and relies on Rx fire to reduce wildfire risk and sustain forest biodiversity. While ecologically beneficial, Rx fires may introduce smoke‐related risks to surrounding communities.

An adaptive grid version of CMAQ for improving the resolution of plumes

Atmospheric Pollution Research, 2010
AbstractAtmospheric pollutant plumes are not well resolved in current air quality models due to limitations in grid resolution. Examples of these include power plant and biomass burning plumes. Adequate resolution of these plumes necessitates multiscale air quality modeling at much finer scales than currently employed and we believe that adaptive grids
