     the earth’s ionosphere is well recognized as a dynamical system and non-linearly coupled with the magnetosphere above and natural atmosphere below. the shape and time variability of the ionosphere indeed shows chaos, pattern formation, random behaviour and self-organization. the present paper studies the propriety of multifractal detrended fluctuation analysis (mf-dfa) technique for the ionospheric scintillation index time series. mf-dfa is used to identify the scaling behaviour of the ionospheric scintillation time-series data of two different nature. the obtained results show the robustness and the relevancy of the mf-dfa technique for the ionospheric scintillation index time series. the comparison of the mf-dfa results of original data to those of shuffled and surrogate series shows that the multifractal nature of considered time-series is almost due to long-range correlations. subsequently, the hurst exponents derived from two parallel methods namely rescaled range analysis (r/s) and auto correlation function (acf) are also suggesting the presence of long range correlation. the presented results in this work may be of assistance for future modeling and simulation studies.
