             abstract = "Good ionospheric modeling is important to understand anomalous 
                         effects, mainly during geomagnetic storm events. Ionospheric 
                         electric fields, thermospheric winds, and neutral composition are 
                         affected at different degrees, depending on the intensity of the 
                         magnetic disturbance which, in turns, affects the electron density 
                         distribution at all latitudes. The most important disturbed 
                         parameter for the equatorial ionosphere is the electric field, 
                         which is responsible for the equatorial ionization anomaly. Here 
                         various electric field measurements and models are analyzed: (1) 
                         measured by the Jicamarca incoherent scatter radar (ISR), (2) from 
                         Jicamarca Unattended Long-Term studies of the Ionosphere and 
                         Atmosphere (JULIA) radar, (3) deduced from magnetometers, (4) 
                         calculated from the time variations of the F layer height (dh0 
                         F/dt), and (5) deduced from interplanetary electric field 
                         determinations. The response of ionospheric parameters foF2 and 
                         hmF2 to the electric fields simulated using the Sheffield 
                         University Plasmasphere Ionosphere Model version available at 
                         Instituto Nacional de Pesquisas Espaciais is compared with 
                         observations for two locations, during the geomagnetic storm 
                         events of 1718 April 2002 and 710 November 2004. Results are found 
                         to be consistent with the observations in such a way that a 
                         hierarchy among the different types of drifts used can be 
                         established. When no ISR measurements are available, the drifts 
                         deduced from magnetometers or measured by the JULIA are best when 
                         including the contribution derived from dh0 F/dt for the 1824 LT 
                         time interval. However, when none of these drifts are available, 
                         drifts inferred from the interplanetary electric field seem to be 
                         a good alternative for some purposes.",
