Abstract
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. This article is part of the Theo Murphy meeting issue 'High-resolution wave dynamics in the lower solar atmosphere'.

Inouye Solar Telescope; [7,8,9]), have paved the way for rapid advancements to be made in the field of lower atmospheric dynamics
Solar physics research is ideally positioned to make rapid discoveries over the coming decades, with the imminent full-scale operation of the 4 m Daniel K. Inouye Solar Telescope (DKIST) facility, in addition to ongoing work linked to the development of the 2 m Indian National Large Solar Telescope (NLST; [51]) and the 4 m European Solar Telescope (EST; [52])
Summary
The topic of waves and oscillations in the Sun’s atmosphere has been a focal point of solar physics research since their first detection over half a century ago [1,2]. 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 When assembling both the original WaLSA team and the larger scientific group present at the Theo Murphy Meeting in February 2020, it was paramount to ensure that diversity, in terms of career stage, gender, race and geographical location, was achieved in order to most readily support the generation of active solar physics researchers in the field. New initiatives including the UK–South Africa Newton Fund and The Royal Society’s International Exchange programmes may help facilitate bilateral involvement with developing African research centres, something which the WaLSA team looks forward to actively engaging with over the coming years
