Use of ground-based observations and integrated networks to study large-scale phenomena in the thermosphere-ionosphere system: Current results and future opportunities

Session ID#: 161823

Session Description:
Understanding the underlying physics responsible for mid-to-large scale (>1000 km) and interhemispheric phenomena in Earth’s thermosphere-ionosphere system has proven challenging due to a relative lack of coordinate measurements and modeling results at the appropriate scales. Recent advances in relatively low-cost and/or mass-deployable instrumentation, and advances in modeling capabilities, are close to solving this challenge. We invite results from current experimental and modeling studies that address mid-to-large scale and interhemispheric phenomena in thermosphere-ionosphere system, especially those that integrate the two. Also of interest are contributions that highlight potential collaborations between modeling and ground-based observing networks, by discussing the necessary measurements to address these phenomena (e.g., interhemispheric neutral dynamics, traveling ionospheric disturbances, equatorial and auroral electrojets, etc.) from a modeling standpoint. Contributions can address the minimum requirements to observe these phenomena including the extension of measurements to locations difficult to access (e.g., oceangoing autonomous surface vehicles, the development/expansion of land-based networks, etc).
