This paper presents a new set of empirical models for describing variations in ionosphere-thermosphere electrodynamics in both hemispheres, as a function of season as well as prevailing solar wind and interplanetary magnetic field conditions. The models are based on combined measurements of magnetic field perturbations and ionospheric plasma drift made by the Swarm and CHAMP satellites. The chief advantage of these models is that they are the first empirical models of high-latitude ionospheric electrodynamics quantities in both hemispheres that are consistently derived. The model codes are open source and publicly available.
