Considering the interaction of the radio wave with the ionospheric electrons cooling would hardly be unexpected. This apparent paradox, is explained using a two fluid continuum theory of incoherent scattering which includes unequal electron and ion temperatures. This analysis demonstrates the expected heating and permits an electron density and collision frequency profile below 100 km to be obtained. The results are obtained using a library of contour plots prepared for this purpose. The library will be useful in future experiments.69 ppengCopyright is held by the author, unless otherwise indicated.
