Coupling Models in Magnetospheric Dynamics: Insights from M-I Interaction and E-Region Density

This document outlines the specifications of numerical data sources related to magnetospheric modeling, focusing on the MM Ring Current Model (RCM) and the Thermosphere-Ionosphere Model (TIM). It describes the interpolation of variables A onto the M-I Coupler (MIC) grid and discusses various coupling methods including 1½-way LFM-RCM and 1-way TING approaches. Emphasis is placed on the iterative processes used to analyze electron density and height in the E-Region, enhancing our understanding of M-I interactions and their implications for active ionization and mass outflow phenomena.
