Abstract:

During the second year of this research program, work has continued on multi-instrument experiments investigating the effects of the large-scale convection electric field in the auroral and mid-latitude ionosphere. A radar-satellite study of electric field latitude structure during the February 8-9, 1986 great magnetic storm was completed and has provided an excellent example of the application of multi-instrument techniques to the investigation of magnetosphere-ionosphere coupling problems. Studies of the high-latitude boundary between auroral and polar cap latitudes have emphasized convection and ionospheric plasma structure near the dayside cusp and the transport of ionospheric plasma into the polar cap during storms. Mesoscale resolution electric field structure was addressed in a multi-instrument study involving the Canadian BARS radar facility and the Millstone Hill incoherent scatter radar.
