Abstract The theory and application of the Assimilative Mapping of Ionospheric Electrodynamics (AMIE) procedure are briefly reviewed. The procedure estimates distributions of electric fields and other electrodynamic quantities over the polar region by synthesis of diverse types of observations. Knowledge of these distributions is important in many areas of magnetospheric, ionospheric, and thermospheric physics. The procedure is a form of optimally constrained, weighted least-squares fit of the electric potential distribution to all relevant data. Applications have shown the value of the results for describing rapidly changing convection patterns, and for evaluating the spatial/temporal variations of important electrodynamic fields needed for simulation models.
