Аннотация:We describe the numerical global photochemical model CHARM (CHemical Atmospheric Research Model) and the results of a numerical simulation of climatological distributions of ozone and other atmospheric trace gases in a height range of up to 90 km. We also present the results of numerical scenarios of an impact induced by a change in UV radiation fluxes in the solar activity cycle and conditioned by ozone depletion in polar regions by high-energy particles of cosmic origin. The spatial transport of chemically active species is described in the model (the Prather scheme) on the basis of global fields of wind components and temperature calculated by the ARM (Atmospheric Research Model) general circulation model.
