Abstract: Small-scale transients, including spicules, jets, and localized brightenings, are increasingly recognized as important contributors to mass and energy transport between the chromosphere and corona. Recent advances in high-resolution solar observations now enable coherent, multi-layer investigations of their origin, evolution, and coupling across different regions of the solar atmosphere. High-resolution observations from ground-based facilities, such as the 1.6-m Goode Solar Telescope, together with space-based measurements from Solar Orbiter, IRIS, and SDO, demonstrate that many chromospheric transients exhibit clear coronal signatures, indicating strong coupling across atmospheric layers. In this presentation, I will discuss the origin of selected small-scale transients in the lower solar atmosphere, including spicules, jets, and small brightening events, and examine their relevance to heating and dynamics in the upper solar atmosphere and beyond. I will highlight the importance of simultaneous, multi-layer observations extending from the chromosphere to the corona, including spectroscopic diagnostics from Aditya-L1/VELC, for advancing a comprehensive physical understanding of chromosphere–corona coupling.
