Abstract

Much of what is known about equatorial ionospheric physics is based on observations of the incoherent scatter and the MST/coherent radar (JULIA) at Jicamarca, Peru [e.g., Chau et al., 2012]. Jicamarca is located in the American sector, where there is a fairly large excursion between the geomagnetic and geodetic equator due to the dip of the geomagnetic equator. However, equatorial ionospheric phenomena, such as equatorial spread F/equatorial plasma bubbles (EPBs), the equatorial electrojet, the strength of the prereversal enhancement (PRE), the dynamo efficiency, and the behavior of thermospheric winds and tides, are all in some way influenced by the regional geomagnetic field, its declination, and the proximity of the magnetic to the geographic equator, all of which vary as a function of longitude.
