Summary: | Analytical results describing the temporal and spatial history of energy deposit in the auroral ionosphere by precipitating particles are presented for the 1973 and '74 ICE CAP experiments. In addition, the role of neutral winds in transporting excited species which alters the expected spatial distribution of infrared radiance is described. Measurements of energy deposit and of Joule heating made by the Chatanika incoherent scatter radar and by optical photometric methods are compared quantitatively. The optical data are used to verify the radar technique for determining energy deposit by precipitating particles. Likewise, radar measurements of electric fields and Joule heating in the auroral ionosphere are used to quantitatively evaluate the three beam photometer method for computing electric fields and Joule heating. A method for determining the temporal and spatial structure of the magnetospheric-ionospheric electric fields is described and several spatial power spectra of the electric field structure during active periods are shown.
