Brief Description:

The Fully Analytical Ionospheric Model (FAIM) uses the formalism of the Chiu model with coefficients fitted to the SLIM model profiles. The local time variation is expressed by a Fourier series up to order 6 and the variation with dip latitude by a fourth order harmonic oscillator function (Hermite polynomial).
