The earth's ionosphere is well recognized as a dynamical system andnon-linearly coupled with the magnetosphere above and natural atmospherebelow.The shape and time variability of the ionosphere indeed shows chaos,pattern formation, random behavior and self-organization. The present paperstudies the propriety of Multifractal Detrended Fluctuation Analysis (MF-DFA)technique for the ionospheric scintillation index time series. MF-DFA is usedto identify the scaling behavior of the ionospheric scintillation time-seriesdata of two different nature.The obtained results show the robustness and therelevancy of the MF-DFA technique for the ionospheric scintillation index timeseries. The comparison of the MF-DFA results of original data to those ofshuffled and surrogate series shows that the multifractal nature of consideredtime series is almost due to long-range correlations. Subsequently, the Hurstexponents derived from two parallel methods namely Re-scaled range analysis(R/S) and Auto Correlation Function (ACF) are also suggesting the presence oflong range correlation. The presented results in this work may be of assistancefor future modeling and simulation studies.
