On the basis of the established empirical dependence between change of concentration of ozone and an aerosol in a ground layer of air in area of Tomsk and a course of solar activity in 21–23 eleven-year cycles (a radio emission on length of a wave of 10.7 cm), on the literary data on the forecast of solar activity on 24th eleven-year cycle, the forecast of change of mid-annual concentration of ozone and an aerosol till 2021 is given. Proceeding measurements of ozone and aerosol and monitoring of solar activity will allow forecast verification.
