High altitude observations made by DE‐1 in the polar regions indicate that the polar wind consists of both a heated and an unheated component. The unheated component constitutes what may be called the “classical polar wind” while the heated component is thought to be the result of the interaction of the primal polar wind with regions of ion perpendicular heating. The altitude at which the heating occurs is estimated to lie between 8000 and 12000 km.
