The paper describes the results of application of the normalized span method to an analysis of temporal series of observations of the atmospheric optical thickness and its aerosol component in the visible and near-IR ranges. The values of the Hurst exponent are shown to differ significantly from H = 0.5, which points to nonrandom character of the formation of atmospheric radiation regime. The revealed coincidence of the H values for the atmospheric optical thickness and its aerosol component confirms the determining role of aerosols in this process and the identity of the mechanisms governing the variation of the examined parameters. The daily variation of aerosol component of atmospheric optical thickness is found to be principally different under enhanced volcanic activity and standard conditions.
