Abstract :
NeQuick2 is a well-known ionospheric model for electron density computation, utilizing the Epstein layer formulation originally proposed by G. Di Giovanni and S.M. Radicella. In this study, algorithm of NeQuick2 model has been employed for ionogram inversion using MATLAB. Critical frequencies of E-layer and F-layer (F2-layer during daytime), and, F-layer propagation factor have been used as ionogram input parameters to compute electron density profile. MATLAB gives more control in data analysis and development of model in advance language. The results have been demonstrated using the ionograms generated by DPS-4 installed at Multan Ionospheric Station (33N, 72E). Comparison of NeQuick2 and ARTIST generated electron density profiles has also been given.
