This document details the specifications for various models and couplers used in magnetospheric studies, including the Magnetospheric Model (MM), Ring-Current Model (RCM), and Thermosphere-Ionosphere Model (TIM). It outlines the interpolation of variables from MM and RCM onto the MIC grid, along with details on empirical couplings like the 1½-way LFM-RCM and 1-way TING couplings. Additionally, it discusses the iterative processes involved in establishing convergent coupling strategies for electron density, loss interactions, and the absorption and reflection of electromagnetic phenomena in the ionosphere.
