Assimilative Mapping of

Ionospheric Electrodynamics

The Assimilative Mapping of Ionospheric Electrodynamics (AMIE) procedure is an optimally constrained, weighted least-squares fit of electric potential distribution to diverse types of atmospheric observations. Knowledge of these distributions is important in many areas of magnetospheric, ionospheric, and thermospheric physics.

Applications of the AMIE procedure have shown the value of describing rapidly changing convection patterns. These data can be of great use in evaluating the spatio-temporal variations of electrodynamic fields needed for simulation models.
