Incorporating AMPERE data into Global Ionosphere-Thermosphere Model simulations: Testing the upper atmosphere response during a Substorm and an SMC event.

We investigate the response of Earths upper atmosphere during two events that occurred on 03/01/2011--a substorm and a steady magnetospheric convection event (SMC), using the 3-D Global Ionosphere-Thermosphere Model (GITM). We will quantify both the Joule Heating rates and the height-integrated ionospheric conductances simulated by GITM during these two event timeframes. In order to specify the convection electric field at high latitudes, we will employ two methods: (1) electric potential patterns during these two events derived from the Active Magnetosphere and Planetary Response Experiment (AMPERE) and (2) the widely used Weimer et al. [2005] empirical model for the high-latitude electric potential. We will compare and contrast the simulated Joule Heating rates and ionospheric conductances determined using these two different approaches in the GITM simulations. For the AMPERE-derived electrodynamic parameters, the methods outlined in Robinson et al. [2020] will be used
