2025 Workshop: Dayside Knowledge Gaps and Planning

Multiscale Dayside Transients play a key role in solar wind–magnetosphere–ionosphere coupling by influencing magnetopause morphology, field‐aligned currents (FACs), auroral dynamics, and magnetopause reconnection processes. Although recent missions such as the Magnetospheric Multiscale (MMS) and advances in hybrid computer simulations have greatly enhanced our understanding, a significant disconnect remains between modeling and observations. This gap stems from the multiscale nature of these events and their dynamic evolution, which spans spatial and temporal scales that challenge both in-situ measurements and modeling tools.

In this session, we will review the key findings from the past decade that have emerged alongside advancements in hybrid modeling, and large-data statistical analysis. Experts from both the modeling and observational dayside research communities will share their perspectives. In addition, presenters with relevant posters will have the opportunity to highlight their work through lightning talks, fostering a vibrant discussion across the community.
