We investigate the plasma mass transport process known as interchange instability using data analysis and modeling. Interchange instabilities are spatially small but ubiquitous flows of hot ambient into cold Enceladus torus, resembling Rayleigh-Taylor within Saturn's inner magnetosphere. Although evidenced with Cassini spacecraft observations, their role in causal relationship large-scale current-sheet collapse injection processes is not well understood. We offer a unifying review...
In this study, a detailed metric survey on the “Galaxy 15” (April 2010) space weather event is conducted to validate MAGNetosphere–Ionosphere–Thermosphere (MAGNIT), semi-physical auroral ionospheric conductance model characterizing four precipitation sources, against AMPERE measurements via field-aligned current (FAC) characteristics. As part of comparative performance three ionosphere electrodynamic specifications involving models, MAGNIT, Ridley Legacy Model (RLM) (empirical), and...
