The solar wind is the primary external driver of Earth’s radiation belt variability. Therefore, understanding the chain of processes connecting upstream solar wind conditions to radiation belt dynamics is crucial to obtain a systemic understanding of the near-Earth
geospace environment. This meeting will bring together the UK and international community spanning observations, modelling, and theory to synthesise current understanding and identify priorities for the next phase of research.</div>

Recent years have produced some of the most intense solar wind driving events on record, captured by an unprecedented constellation of spacecraft, including the Solar Orbiter and Parker Solar Probe providing upstream solar wind measurements, together with radiation
belt observations from ERG/Arase, MMS, and THEMIS, along with the upcoming joint ESA/CAS SMILE mission. This is therefore a timely opportunity for the space weather community to come together and synthesise this remarkable observational resource.</div>
