With a special set of planar probes, the Japanese satellite, AKEBONO has continued electron temperature (Te) measurement up to the height of ∼10000 km in all latitude ranges, since its launch in 1989. Although the data are still being analyzed and the results obtained so far are preliminary, we discuss the height profiles in the latitude range which is lower than 60 degrees, in terms of local time, geomagnetic latitude and seasonal variations. Although quite a large amount of theoretical work on the thermal structure of the high altitude has been done so far, the results obtained by means of the satellite AKEBONO, present a first systematic picture of the inner plasmasphere of the earth.
