“…However, specific modules of the model described above were verified using measurement data. In particular, a comparison between calculated and observed data is performed for the results of the photochemical model and the aerosol model (Aloyan et al, 1997). The models considered can be used to solve a wide range of environmental problems related to the investigation of the regional-scale spatio-temporal dynamics of gaseous admixtures and aerosols in the atmosphere.…”

“…At present, there are many models for aerosol dynamics as described among others by Aloyan et al (1993), Wexler et al (1994), Aloyan et al (1997), Piskunov et al (1997), Ackermann et al (1998), Meng et al (1998, Aloyan (2000), Piskunov (2000). Most three-dimensional models for aerosol dynamics assume an instantaneous equilibrium in the gasaerosol system.…”

“…In this case, one or two parameters (or moments) of the spectrum are calculated. Compared to the generalized approach, the direct approach is more accurate in describing the evolution of the particle size spectrum, but requires considerable computational resources, because the spectrum needs to be split into many intervals (Aloyan et al, 1993;Wexler et al, 1994;Aloyan et al, 1997;Piskunov et al, 1997;Meng et al, 1998;Aloyan and Piskunov, 2005). In each case, the choice of an approach depends on the purpose of the study and the availability of accompanying resources.…”

“…The basic models for the description of the spatio-temporal variations in concentrations of gaseous admixtures and aerosols can be found in Aloyan et al (1993), Aloyan et al (1997), Piskunov et al (1997), Aloyan (2000) and Aloyan and Piskunov (2005).…”

A combined mathematical model was developed for the regional-scale dynamics of gaseous admixtures and aerosols in the atmosphere. The model incorporates the following modules: thermo-hydrodynamic equations for meso-scale atmospheric processes in the non-hydrostatic approximation; transport of gaseous admixtures and aerosols, with allowance for photochemical transformation and binary homogeneous nucleation; and kinetic processes of condensation/evaporation and coagulation. Particular emphasis is given to the mechanisms of new-particle formation through binary homogeneous nucleation of drops of sulfuric acid and water vapor. By using this model, numerical experiments were performed to investigate spatio-temporal variations in the concentrations of gaseous admixtures and aerosols, as well as the formation of fine aerosol clusters in the Lake Baikal (Russia) and Antwerp (Belgium) areas due to strong industrial emission sources. The results of the numerical experiments are analyzed.

A comparative study of the structure and fractal properties of arrays of the silver nano-/micro-particles deposited on the silicon substrate both from the aerosol and fog showed that the form of the silver individual particles and nano-/microstructures greatly depends on the deposition conditions. By passing an aerosol through isopropyl alcohol, the formation of fractal aggregates of the silver nano-/micro-particles both in the air and in alcohol was observed. Deposition of the silver nano-/micro-particles in the atmosphere of the saturated isopropyl alcohol vapours led to formation of fog. Microdroplets of the silver colloidal solution were deposited on the substrate. The further evaporation of alcohol created the silver nano/microstructures in the form of annular layers. It was found that the concerned annular layers contained silver particles of the same shape in the form of a Crescent (or Janus-nano-/microparticles). The nature of discovered effects is discussed.
