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).

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 ...

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.

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.

Meteorological and Emission Drivers of Compound Heat and Ozone Pollution Episodes in Oklahoma City During Periods Influenced by Atlantic Tropical Cyclones

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 17, 16 September 2026.
Abstract Compound heat and ozone (O3) pollution events are widespread and pose significant health risks in urban areas. In the Southern Great Plains (SGP), where heat waves are becoming more frequent and intense, these compound events represent a growing environmental and public health concern, underscoring the need for improved process‐based ...

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-

Fine‐Scale Population, Emissions, and Atmospheric Dynamics Drive Health Disparity Outcomes From Energy Transition

Earth's Future, Volume 14, Issue 9, September 2026.
Abstract Transitioning to a low‐carbon energy system can provide air quality and health co‐benefits. While the aggregate effects are intuitively clear, the distributions across subnational regions and population groups and their drivers are complex and less intuitive. Here we use an integrated energy‐atmospheric‐health modeling framework for the United
