Abstract We treat the global-scale modelling and measurement activities of the SUNDIAL campaign of September 1986 and investigate averaged, quite-time, and dynamic ionospheric behavior. Treatment is given to developments in empirical and first-principle models; and we investigate various aspects of magnetospheric-thermospheric-ionospheric coupling mechanisms. Overall results point to good empirical model specification of averaged F-region behavior, with suggestions for improvements in specification of layer peak densities near and across the sunset terminator. We elucidate the difficulties in achieving a unique determination of electric fields, thermospheric winds, and plasmaspheric fluxes in first-principle model attempts to reproduce global observations of quiet-time F-region heights and densities. In this connection, and in our treatment of magnetospherically-imposed electric field influences on low-latitude F-region dynamics, we show a greater need for comprehensive measurements of auroral oval dynamics, thermospheric winds, electric fields, ion composition, and ionospheric layer heights and densities; and we discuss the growing importance of the lower regions of the ionosphere and thermosphere and the associated controls of dynamo-driven electric fields.
