Air quality modeling for Houston–Galveston–Brazoria area

Modeling the Regional Dynamics of Gaseous Admixtures and Aerosols in the Areas of Lake Baikal (Russia) and Antwerp (Belgium)

“…For a more detailed study of the photochemical effect (taking into account the diurnal course) on aerosols, additional numerical experiments are required, which can be analyzed in a new paper aimed specifically at studying the sensitivity of concentrations of nucleation-mode particles to variations in the chemical reaction rates conditioned by the diurnal course. Note that similar data as applied to specific regions can be found in (Aloyan et al, 1995(Aloyan et al, , 2003. As can be seen from the above figures the Antwerp atmosphere is characterized by an intense formation of nucleation-mode particles, which may significantly affect the spatial and temporal variability of SO 2 and H 2 SO 4 concentrations as well as the aerosol particle-size distribution.…”

“…The main aim of our paper is to study the gas-aerosol interaction and formation of nucleation-mode particles (in the H 2 SO 4 -H 2 O system). The study of the gaseous composition of the atmosphere without consideration of aerosols has been performed earlier (Aloyan et al, 1995(Aloyan et al, , 2003. It is clear that the photochemical processes significantly affect the concentrations of such species as O(…”

“…Chemical reactions initiated by sunlight lead to the formation of new chemically active atoms, free radicals, and other species, which, together with the primary emissions, constitute the following system: {O( (Aloyan et al, 1995;Aloyan et al, 2003;Aloyan, 2005). It should be noted that the formation of nucleationmode particles involves only water vapor and sulfuric acid particles.…”

Numerical Modeling for Enhanced Pollutant Transport Prediction in Industrial Atmospheric Air

“…A combined numerical model of atmospheric thermohydrodynamics and photochemical transport of pollutants is described by Aloyan et al [27]. This model is used to study the complex relationships between chemical and thermohydrodynamic processes in the atmosphere of urban areas, with a main focus on photochemical transformations.…”
