B0B1_qModel

The B0B1 Model calculates the thickness B0 (km) and shape B1 (dimensionless) parameters of the F layer under quiet conditions on the basis of climatological models. This empirical model has been constructed by using long time series obtained from different world-wide-distributed ionosonde stations. Spherical harmonic analysis is used as analytical technique for modeling globally the B0 and B1 parameters as general functions on a spherical surface. By using the predicted smoothed sunspot number and the newest IGRF coefficients at any location distributed along the used range of latitudes (70N–70S). Model parameters can be computed either to reproduce already observed values or to perform predictions until December 2029.
