The magnetic and convective nature of the Sun's photosphere provides a unique platform from which generated waves can be modelled, observed and interpreted across a wide breadth of spatial and temporal scales. As oscillations are generated in-situ or emerge through the photospheric layers, the interplay between the rapidly evolving densities, temperatures and magnetic field strengths provides dynamic evolution of the embedded wave modes as they propagate into the tenuous solar chromosphere. A focused science team was assembled to discuss the current challenges faced in wave studies in the lower solar atmosphere, including those related to spectropolarimetry and radiative transfer in the optically thick regions. Following the Theo Murphy international scientific meeting held at Chicheley Hall during February 2020, the scientific team worked collaboratively to produce 15 independent publications for the current Special Issue, which are introduced here. Implications from the current research efforts are discussed in terms of upcoming next-generation observing and high-performance computing facilities.

Bibliographical noteFunding Information:
Funding was provided by The Royal Society Hooke Committee, through the award of a Theo Murphy Meeting that would take place at Chicheley Hall, England, UK, during 10–11 February 2020 (figure 1). Including the 12 core WaLSA team members, the Theo Murphy Meeting welcomed 28 participants from around the world for an intensive 2-day meeting. Following the successful presentations and discussions at the ‘High-resolution wave dynamics in the lower solar atmosphere’ meeting, sufficient scientific momentum was generated to enable a special themed issue of the Philosophical Transactions of the Royal Society A (https://royalsocietypublishing.org/journal/rsta) to be published based on the scientific achievements of the participating cohort and their extended collaborative networks.
