abstract = "In this Part I of a more general paper on the analysis of
ionospheric irregularities over Brazilian territory, we apply the
Detrended Fluctuation Analysis (DFA) method to evaluate in situ
equatorial F-region plasma bubbles events carried out with a
sounding rocket over equatorial region in Brazil. The range of
scaling exponents derived from the DFA technique are compared to
previous results obtained using Power Spectral Density (PSD)
technique (which is widely used in this area despite its
recognized inaccuracy to analyze short series). The results
obtained in this first part of our investigation, using DFA, also
show a wide range of spectral index variation with standard
deviation of the same order found from the previous application
using PSD (\σm\≫10%). Therefore, since the dependence
of the technique are disregarded, our findings also supports that
the observed lack of a universality class characterized by the
nonexistence of a single spectral index (with
\σm\≈2%) may be due to non-homogeneity energy
cascades that can appear in the incoherent ionospheric turbulent
process.",
