Earth's ambipolar electric field is a key element of a theory about an electric field which surrounds the planet and, by the process of ambipolar diffusion, inflates the ionosphere and generates the polar wind.

Voltage measurements done from a rocket traveling thru space
editVarious voltage measurements were done, during a rocket-flight in 2022. What is thought to be a polarization electric field (also known as ambipolar electric field), seems to have been measured. Later measurements, if even made, have not been published (as of Q3 2024).
The field was measured in 2022 by a sounding rocket launched from Svalbard. This NASA mission was called Endurance.[1] The potential drop from 250 to 768 kilometres of altitude was found to be +0.55 volt with an uncertainty of 0.09 volt.[2]
