A dynamical model of the ionospheric conductivity distribution has been developed using ground magnetic data. The model is based on the Spiro et al. (1982) average conductivity models, but adjusts their latitudinal distribution to the instantaneous distribution of field-aligned currents calculated from the equivalent current function. It can thus take into account the dependence of the conductivity distribution on fluctuations of solar wind parameters and magnetospheric disturbances. A comparison of electric fields calculated from the equivalent current function and the new conductivity model with those measured by the STARE radars, shows that the present conductivity model gives better results than obtained by using the same current function but earlier conductivity models.
