Abstract
: In recent years, the understanding of various phenomena pertaining to space science and consequently the predictability of naturally occurring phenomena have improved. Wavelet is a tool for displaying and analyzing data and wavelet basis are considered a useful tool for understanding local behavior. Ionosphere F2 layer is situated at about 250–425 km from above the earth surface; this is a region of magnetosphere. Therefore, there exist some ionospheric effects due to solar activity and diurnal variation. In this study, we analyzed computed perturbed and un-perturbed parcel velocities of ionospheric F2 layer using spectral and wavelet analysis. The level 5 of Haar wavelet has been reported in the forms of approximation model, detailed statistics and reconstructed model by decomposition. In this communication we have presented the comparison of wavelet characterization for computed perturbed and un-perturbed parcel velocities of ionospheric F2 layer at the Pakistan air space
