Abstract:

Data were obtained from a rocket-borne Langmuir probe experiment up to an altitude of 220 kilometers above Fort Churchhill, Canada, in a quiet daytime ionosphere. The electron temperatures deduced from the probe data are in good agreement with the accepted neutral gas temperatures at altitudes above 140 km. Improper corrections for the positive ion component of the diffusion current to the rocket, which component is adversely affected by the high rocket velocity, are thought to be the cause for the much higher electron temperatures measured below 140 km. The rocket-to-plasma potential was measured as 12 to 1 volt negative. Author
