             abstract = "Ionospheric irregularities are nonlinear phenomena and its key 
                         source are the plasma instabilities and the signature of an 
                         underlying turbulent process has long been investigated using 
                         Power Spectral Density methods. However, it is evident that 
                         ionospheric data exhibits a complex nonlinear spatiotemporal 
                         behavior and has richness of scaling but its underlying process is 
                         very hard to characterize (Fornari et al., 2016). Beyond the 
                         traditional PSD analysis, the multifractal structure function is 
                         able to characterize much more complex process such as 
                         nonhomogenous energy cascade. In this work, we applied both the 
                         multifractal detrended uctuation analysis (MFDFA) algorithm 
                         (Kantelhardt et al., 2002) and p-model (Meneveau and 
                         Sreenivasan,1987) in order to rene the interpretation of 
                         ionospheric data from E-F transition region obtained from a rocket 
                         experiment. This procedure is relatively unprecedented since the 
                         study of equatorial E-region and the intermediate region between 
                         the E and F layers at night time are sparse (Sinhaet al., 2011) 
                         and not much references are available. Earlier results (Odriozola 
                         et al., 2017) from this data using PSD method has shown the 
                         presence of a dual slope under the presence of complex small and 
                         medium scale plasma irregularities. Singularity spectra obtained 
                         from MFDFA analysis can be tted using the p-model input 
                         parameters. The preliminary results we have obtained are 1.66 < 
                         PSD < 2.00 and 0.35 < p < 0.6 suggesting that the main underlying 
                         physical process is the nonhomogenous multiplative cascade. The 
                         results on scaling pattern obtained from singularity spectra and 
                         tted p-value helps in understanding the nature of ionospheric 
                         turbulence in the EF transition region.",
