Formation and Evolution Mechanisms of A Severe Haze Event in the Sichuan Basin in Winter 2016

Gaoyuan qixiang
Studying the formation and evolution mechanism of heavy pollution haze events is beneficial to control the regional scale air quality and to formulate the prevention policies of severe haze pollution.Based on the WRF-CMAQ model and actual observation ...

Summertime weekly cycles of observed and modeled NO_x and O₃ concentrations as a function of satellite-derived ozone production sensitivity and land use types over the Continental United States [PDF]

Atmospheric Chemistry and Physics, 2012
To show how remote-sensing products can be used to classify the entire CONUS domain into "geographical regions" and "chemical regimes", we analyzed the results of simulation from the Community Multiscale Air Quality (CMAQ) model version 4.7.1 over the ...

Modelling Saharan dust transport into the Mediterranean basin with CMAQ [PDF]

Atmospheric Environment, 2013
The need for a better quantification of the influence of Saharan dust transport processes on the air quality modelling in the Mediterranean basin led to the formulation of a dust emission module (DEM) integrated into the Air Quality Risk Assessment System for the Iberian Peninsula (SERCA).

Psychometric Properties of the Revised Child Mathematics Anxiety Questionnaire (CMAQ-R) for Spanish Speaking Children

Psicología Educativa: Revista de los Psicólogos de la Educación, 2021
Mathematics anxiety (MA) has primarily been studied in adults and children over 8 years of age in English-speaking countries. Few studies have examined MA in younger children and in Spanish-speaking contexts due to the lack of suitable instruments.

Modeling of Organic Aerosol in Seoul Using CMAQ with AERO7

Atmosphere, 2023
The Community Multiscale Air Quality (CMAQ) model with the 7th generation aerosol module (AERO7) was employed to simulate organic aerosol (OA) in Seoul, Korea, for the year 2016. The goal of the present study includes the 1-year simulation of OA using WRF-CMAQ with recently EPA-developed AERO7 with pcVOC (potential VOC from combustion) scale factor ...

Evaluation of a regional air-quality model with bidirectional NH₃ exchange coupled to an agroecosystem model [PDF]

Biogeosciences, 2013
Atmospheric ammonia (NH3) is the primary atmospheric base and an important precursor for inorganic particulate matter and when deposited NH3 contributes to surface water eutrophication, soil acidification and decline in species biodiversity.

Exposure to Airborne Particulate Matter in Regional Environments of Bangladesh and Its Effects on Respiratory Health: A Narrative Review

Health Science Reports, Volume 9, Issue 8, August 2026.
ABSTRACT Background Air pollution represents a critical public health crisis in Bangladesh, driven by rapid industrialization, urbanization, and widespread emissions from brick kilns, traffic, and biomass burning. Elevated levels of fine particulate matter and toxic gases across both urban and rural regions contributes to significant reductions in life

Model Performance Differences in Sulfate Aerosol in Winter over Japan Based on Regional Chemical Transport Models of CMAQ and CAMx

Atmosphere, 2018
Sulfate aerosol (SO42−) is a major component of particulate matter in Japan. The Japanese model intercomparison study, J-STREAM, found that although SO42− is well captured by models, it is underestimated during winter. In the first phase of J-

From Static to Spatiotemporal: Dynamic Volatility Distribution Parameterizations for Global Organic Aerosol Simulations

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 8, August 2026.
Abstract Organic aerosols (OA) are a major component of fine particulate matter that affects air quality and climate, yet atmospheric models often underestimate their concentrations, partly reflecting uncertainties in the assumed volatility distribution of primary organic aerosol emissions.
