This session invites submissions concerning magnetosphere-ionosphere coupling using a combination of space and ground-based observations, or comparisons between space and ground-based observational datasets.
The upcoming joint ESA-CAS SMILE mission will make novel simultaneous images of the dynamic magnetopause and northern hemisphere auroral oval, as well as in-situ plasma measurements at the spacecraft location. SMILE will help develop our scientific understanding of global magnetospheric-ionospheric dynamics by monitoring dayside driving of the magnetopause using an X-ray imager and the subsequent response of the ionosphere using a global UV imager. Since the end of the IMAGE and POLAR missions in the mid-2000s, global auroral imagery has been sparse, which has challenged the study of magnetosphere-ionosphere coupling and dynamics. The lack of continued UV auroral data has nevertheless built an observational basis which will complement the SMILE mission: spacecraft constellations (e.g. AMPERE, SWARM, Cluster), in-situ spacecraft (e.g. DMSP) and ground-based networks (e.g. global networks such as SuperDARN or SuperMAG, plus many other localised experiments, e.g, EISCAT/EISCAT-3D and ground-based auroral imagers). Ground-based observations are taken on multiple spatial and temporal scales and allow inter-hemispheric comparisons.
The global UV auroral images provided by SMILE and coincident magnetopause observations will provide an exciting new perspective at the cutting edge of magnetospheric science. The SMILE Ground-based and Additional Science Working Group hopes to encourage cross-disciplinary studies using the observations from SMILE in conjunction with observations from well-established ground-based networks, constellations and in-situ data.
The scientific advances from the SMILE mission will be invaluable to developing our understanding of the magnetospheric and ionospheric dynamics. In this session we will discuss how the SMILE mission can be best supported by additional science and the ongoing work that is building our understanding of solar wind-magnetosphere-ionosphere coupling.
We particularly welcome submissions to this session which use a combination of both ground and space-based observations and/or which cover the following topics:
• Solar wind-magnetosphere-ionosphere coupling
• Auroral dynamics
• Dayside magnetosphere/ionosphere/aurora
• Case study events
• Cusp regions
