Welcome to the Assimilative Mapping of Ionospheric Electrodynamics (AMIE) homepage at the University of Michigan.

I have recently run AMIE for 12 years (1991 - 2002) using as many ground-based magnetometers as I could find. The runs are done with a 1 minute cadence. I have run both Northern and Southern hemispheres for 1997-2001, but only the Northern hemisphere for the other years.

This site was created to share the output from the AMIE runs. You can get line plots of the cross polar cap potential, AE, hemispheric power index, Joule heating, polar cap area, and Dst. These are all derived from the AMIE runs. In addition, you can get maps of the potential, electric field, currents, Joule heating, conductance, and particle precipitation from the 1 minute runs. Start here!

At this time, the data is not available over the web site, but you can request it by e-mailing me (ridley @ I can provide IDL save files and plotting software, if you need that.

AMIE is being used in the Global Ionosphere Thermosphere Model, so we have created a generic interface to this code from AMIE. If you would like to drive your model with AMIE results, please let me know, and I can give you a fortran program to read in the AMIE output and provide maps of particle precipatation and potential (or electric fields) in magnetic or geographic coordinates.

We are extremely grateful to all those who provided us data for this project. Please see our Data Page to see who provided all of the incredible data!
