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).<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>The deadline for all submissions is <b>Wednesday, 3 August 2022 at 23:59 EDT.</b> <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Best regards,<o:p></o:p></p><p class=MsoNormal>Rafael Mesquita, Jonathan Makela, Igo Paulino, Jesper Gjerloev.<o:p></o:p></p></div></body></html>
