On calculating ionospheric conductances from the flux and energy of precipitating electrons
Auroral zone conductances can be estimated from the energy flux and average energy of precipitating electrons. Revised expressions are presented that relate height-integrated Hall and Pedersen conductance to the flux and average energy of a Maxwellian. It is shown that the accuracy of this method de...

Auroral zone conductances can be estimated from the energy flux and average energy of precipitating electrons. Revised expressions are presented that relate height-integrated Hall and Pedersen conductance to the flux and average energy of a Maxwellian.

It is also confirmed that the conductances produced by some of the more common auroral spectral distributions are similar to those produced by a Maxwellian with the same average energy and energy flux. The application of these results is demonstrated using precipitating electron measurements made by the Hilat satellite during a pass over Greenland. |
