dc.description.abstract | A self‐consistent approach to superthermal electron (SE) transport along closed field lines in the inner magnetosphere is used to examine the concept of plasmaspheric transparency, magnetospheric trapping, and SE energy deposition to the thermal electrons. The dayside SE population is generated both by photoionization of the thermosphere and by secondary electron production from impact ionization when the photoelectrons collide with upper atmospheric neutral particles. It is shown that a self‐consistent approach to this problem produces significant changes, in comparison with other approaches, in the SE energy exchange between the plasmasphere and the two magnetically conjugate ionospheres. In particular, plasmaspheric transparency can vary by a factor of two depending on the thermal plasma content along the field line and the illumination conditions of the two conjugate ionospheres. This variation in plasmaspheric transparency as a function of thermal plasma and ionospheric conditions increases with L ‐shell, as the field line gets longer and the equatorial pitch angle extent of the fly‐through zone gets smaller. The inference drawn from these results is that such a self‐consistent approach to SE transport and energy deposition should be included to ensure robustness in ionosphere‐magnetosphere modeling networks. Key Points A self‐consistent approach alters the SE energy exchange in the I‐P system Plasmaspheric transparency varies with the thermal plasma and illumination SE transport and energy dep should be included in M‐I modeling networks | en_US |
