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.

Sensibility Study for PBL Scheme of WRF-CMAQ

Journal of Korean Society for Atmospheric Environment, 2011
Numerical simulations were carried out to investigate the impact of PBL (Planetary boundary layer) scheme implemented in WRF on the result of meteorological fields and CMAQ modeling. 25-day period, representing high ozone concentration, was selected for the simulations.

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 ...

Wildfire Smoke and Cardiorespiratory Emergency Visits in New Mexico 2022: Sensitivity to Exposure Estimates and Referent Periods

GeoHealth, Volume 10, Issue 7, July 2026.
Abstract In 2022, New Mexico (NM) experienced a number of wildfires, including the state's largest, Calf Canyon/Hermit's Peak. This study aimed to evaluate how different exposure estimate methods and referent period selection impacted associations between wildfire smoke and health outcomes using a case‐crossover study design.

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

Simulation of GOES-R ABI aerosol radiances using WRF-CMAQ: a case study approach [PDF]

Atmospheric Chemistry and Physics, 2014
In anticipation of the upcoming GOES-R launch we simulate visible and near-infrared reflectances of the Advanced Baseline Imager (ABI) for cases of high aerosol loading containing regional haze and smoke over the eastern United States.

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 ...

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
