Long-term variability of ozone and aerosol concentrations in the atmosphere surface layer and forecasting its changes from the solar activity level predicted in cycle 24

We consider long-term changes in ozone and aerosol concentrations around Tomsk Academgorodok. The changes are assumed to correlate with solar activity. Results of the cycle 23 forecast are compared to the observational data. The forecast was proved to be nearly correct for aerosol, whereas for ozone it is much worse. The forecast for the cycle 24 is given.
