<div>ID: 2821</div><div><br></div><div>Session Description: </div><div>Our knowledge about the Earth-sun interaction is to a large extent based on measurements from only the northern hemisphere. Recent datasets (SuperDARN, SuperMAG, AMPERE, satellite imaging and statistics from satellites such as CHAMP, Cluster and Swarm) provide measurements of several key parameters from both hemispheres simultaneously. Studies reveal that there are important differences between the hemispheres that depend on external drivers and on differences in ionospheric and thermospheric feedback (M-I-T coupling). This session calls for papers exploring interhemispheric asymmetries, and high latitude geospace as a two-hemisphere system. We welcome studies using conjugate observations, statistical techniques, as well as simulations and theoretical considerations.</div>
