The fluctuations of refraction coefficients can be described by a stochastic process: a two-component process. One component of the process is caused by short-periodic (daily) climatic variations. The other component is influenced by long-periodic (yearly) climatic variations. The central moments of these two components are used to estimate the covariance matrix of time series of refraction coefficients. Different functional and stochastic models are tested in connexion with time averaging of refraction coefficients.
