Observation of isotropic electron temperature in the turbulent E region

Observation of isotropic electron temperature in the turbulent E region

Using EISCAT radar data, we find that electrons are strongly heated in the magnetic field-line direction during high electric field events. The remote site data show that the electron temperature increases in almost the same way in the field-perpendicular direction; electron heating by E region...
