Abstract
In constrast to the conventional thinking that there is no
significant electric field in the subauroral ionosphere, recent
studies have indicated that the subauroral ionosphere is not a quiet
region at all. Stastical studies using the Millstone Hill
mid-latitude inconherent scatter radar and the Manastash Ridge
passive radar indicate that the ionosphere at middle latitude at time
can have significant electric field. The subauroral polarization
stream can profoundly effect the 'boring' inosphere as electron
density enhancement by a factor of 10 has been observed. Preliminary
modeling of the ionosphere with the inclusion of SAPS indicates that
there could be significant difference in the American and European
ionosphere. LOIS has the potential to be used as a passive
ionospheric radar to monitor the behavior of sub-auroral electric
field. Review of the on going experimental and theoretical work in
this line of research will be given in this talk.
