Chemically speciated concentrations of PM2.5 (sulphate, ammonium, nitrate, elemental and organic carbon) were simulated in south-west Europe using the three-dimensional air quality model CAMx driven by the MM5meteorological model. The inner domain covered the south-west region of Spain with a high spatial (2 km 2 km) and temporal resolution (1 h). The simulation results were evaluated against e...

For the assessment of regional to local air quality in urban and industrial areas, a system of coupled models (AirWare) that cover several levels of nesting from regional (several hundred kilometers) to city level and street canyons has been developed in EUREKA E!3266 WEBAIR. The main objectives are to support regulatory tasks, compliance monitoring, and public information, and to provide a rel...

Over the next several years, grid-based photochemical models such as the community multiscale air quality (CMAQ) model, the regional modeling system for aerosols and deposition (REMSAD), the comprehensive air quality model with extensions (CAMx), and other regional models will be used by regulatory agencies in the United States for designing emission control strategies to meet and maintain the ...

Abstract. Urban areas are hot spots of intense emissions, and they influence air quality not only locally but on a regional or even global scale. The impact urban emissions over different scales depends the dilution chemical transformation plumes which governed by local- regional-scale meteorological conditions. These influenced presence urbanized land surface via so-called canopy forcing (UCMF...

Abstract. The Tropospheric Monitoring Instrument (TROPOMI) on the Sentinel-5 Precursor (S5P) satellite is a valuable source of information to monitor NOx emissions that adversely affect air quality. We conduct series experiments using 4×4 km2 Comprehensive Air Quality Model with Extensions (CAMx) simulation during April–September 2019 in eastern Texas evaluate multiple challenges arise from rec...

We use regional air quality modeling to evaluate the impact of model resolution on uncertainty associated with the human health benefits resulting from proposed air quality regulations. Using a regional photochemical model (CAMx), we ran a modeling episode with meteorological inputs simulating conditions as they occurred during August through September 2006 (a period representative of condition...
