We consider satellite time series concerning the atmospheric aerosol content.We prove that these time series are well described by a stochastic dynamical model. The principal peak in the power spectrum of these signals can be explained by stochastic resonance, linking variable external factors, such as Sun- Earth radiation budget and local insolation, to fluctuations on smaller spatial and temporal scale due to internal weather and antrophic components

Abstract
We consider satellite time series concerning the atmospheric aerosol content.We prove that these time series are well described by a stochastic dynamical model. The principal peak in the power spectrum of these signals can be explained by stochastic resonance, linking variable external factors, such as Sun- Earth radiation budget and local insolation, to fluctuations on smaller spatial and temporal scale due to internal weather and antrophic componentsFile in questo prodotto:
