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 ...

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.

Improving Air Quality Simulations in California's San Joaquin Valley Using Land Surface Remote Sensing

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.
Abstract Accurate regional air quality modeling is crucial for the development of effective air pollution mitigation plans. Precisely simulating meteorological conditions, especially planetary boundary layer (PBL) properties, is challenging due to complex land surface conditions.

Assessing Near‐Source Health and Equity Impacts of Liquefied Natural Gas Terminals

GeoHealth, Volume 10, Issue 4, April 2026.
Abstract Growing global demand for natural gas has driven the expansion of liquefied natural gas (LNG) export terminals, which emit pollutants that can pose health risks to nearby communities. This study presents a novel modeling framework using the AMS/EPA Regulatory Model (AERMOD) to assess near‐source nitrogen dioxide (NO2) exposure, health impacts,

Atmospheric Ammonia Deposition: A Significant Source of Nitrogen to an Oligotrophic Lake and Its Watershed

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 4, April 2026.
Abstract The increasing frequency of toxic cyanobacterial blooms (TCBs) in freshwater lakes in recent years has been problematic, both in terms of our understanding of basic drivers, and attempts to manage them. While phosphorus has been determined to limit the growth of blooms, some cyanophytes manufacture toxins with a high nitrogen (N) demand, so ...

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

TOMO4D Operator for Assimilation of GNSS Tomography‐Derived Water Vapor Fields Into the WRFDA 4DVAR System to Improve Regional Rainfall Forecasting

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 4, April 2026.
Abstract Accurate representation of atmospheric water vapor is crucial for improving numerical weather prediction, particularly over regions with complex topography and sparse observation networks. Although assimilation of Global Navigation Satellite System (GNSS)‐derived integrated products such as zenith total delay or precipitable water vapor can ...
