Sensitivity of Regional WRF‐Chem Air Quality and Weather Simulations to Biomass‐Burning Emission Data Sets: A Case Study of the Impact of Canadian Wildfire on the US

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 22, 28 November 2025.
Abstract This study focuses on the period from June 26 to 29, 2023, when record‐breaking Canadian wildfires severely impacted air quality in the Midwest United States. Using the Weather Research and Forecasting Model with Chemistry (WRF‐Chem) and four biomass‐burning data sets (Fire Inventory from NCAR version 1, Fire Inventory from NCAR version 2.5 ...

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).

Timely Updates of Anthropogenic Emission With Satellite and Ground Observations: Comparison of Multiple Top‐Down Methods Against Bottom‐Up National Emission Inventories

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 22, 28 November 2025.
Abstract Due to the COVID‐19 pandemic and changes in technology and energy consumption, recent years saw substantial variations in air pollution emissions, highlighting the importance of timely emission updates. In the United States, the level of surface ozone in many regions is close to the National Ambient Air Quality Standard, making it important to

A regional carbon data assimilation system and its preliminary evaluation in East Asia [PDF]

Atmospheric Chemistry and Physics, 2015
In order to optimize surface CO2 fluxes at grid scales, a regional surface CO2 flux inversion system (Carbon Flux Inversion system and Community Multi-scale Air Quality, CFI-CMAQ) has been developed by applying the ensemble Kalman filter (EnKF) to ...

Comparisons of High Spatiotemporal Resolution Air Quality Modeling Frameworks for Prescribed Burning Simulations at a Military Base in the Southeastern United States

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 22, 28 November 2025.
Abstract High spatiotemporal resolution air quality modeling is essential for air quality impact assessments and decision‐making for prescribed burns. Accurate representation of the heterogeneous distribution of fuels and the structure of smoke plumes requires high‐resolution modeling frameworks.

Extracting gradients from community data with multiple stressors and empty plots: A case study and simulations

Ecosphere, Volume 16, Issue 10, October 2025.
Abstract Ecological community data are used to infer levels of environmental stressors; for example, epiphytic lichen communities can be used to estimate levels of air pollutants. If stressors are so severe that the community of interest disappears altogether, then “empty” plots are recorded.

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
