A study on the aerosol optical properties over East Asia using a combination of CMAQ-simulated aerosol optical properties and remote-sensing data via a data assimilation technique [PDF]

Atmospheric Chemistry and Physics, 2011
To more accurately estimate direct radiative forcing (DRF) by aerosols, and better investigate particulate pollution over East Asia, precise calculations of the optical properties of aerosols, such as aerosol optical depth (AOD), single scattering albedo

Fire Moderation in Southeast Asia Mitigates the Adverse Effects of Aerosols on Spring Green‐Up

Earth's Future, Volume 14, Issue 7, July 2026.
Abstract Transboundary fire‐derived aerosols in Southeast Asia pose a persistent regional environmental challenge, with impacts extending beyond air quality to ecosystem function and carbon dynamics, yet their effects on seasonal phenology remain poorly understood.

Modeling Patterns of Population Exposure With a Multiscale Framework Utilizing LOTOS‐EUROS Chemical Transport Model, Mobility Surveys and Particulate Toxicity

GeoHealth, Volume 10, Issue 7, July 2026.
Abstract The present study proposes a high‐resolution, multi‐component framework to estimate human exposure to air pollution in tropical urban environments, addressing complex topography and limited historical mobility and exposure data. This framework is applied to the city of Medellín in the Aburrá Valley in Colombia. To assess population exposure to

Application of CMAQ at a hemispheric scale for atmospheric mercury simulations [PDF]

, 2011
Abstract. Application of a regional model to study of fate and transport of a global pollutant such as mercury in the atmosphere can be challenging and improper usage of models may lead to questionable results. The difficulties in such application stem from the fact that regional models are usually used in relatively small domains and rely heavily on ...

Modeling the Distribution, Impacts, and Mitigation of Anthropogenic Heat in Los Angeles

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.
Abstract Anthropogenic heat emissions from human energy consumption contribute to the urban heat island (UHI) effect, yet their spatiotemporal distributions and impacts remain uncertain. In this study, we develop a 100 m resolution, hourly anthropogenic heat flux (AHF) data set for Los Angeles County and use the Weather Research and Forecasting model ...

Can Deep Learning Improve CMAQ Performance?

, 2019
Three-dimensional Eulerian chemical transport models such as CMAQ often report a significant model-measurement error due to uncertainties in the treatment of physical processes and require higher run-time. Machine models are more computationally efficient and are currently used widely for forecasting purposes.

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
