Pulsating aurora (PsA) is known as one of the major classes of aurora, which almost always appears during the recovery phase of substorm. Since 1960s, PsA has been extensively studied by using ground-based observations combined with rocket and satellite measurements. Still, however, the underlying processes creating auroral pulsations remain to be understood. Because of these, vast numbers of ground-based optical and radio instruments have been employed during the last decade to better observe the dynamic nature of PsA. In addition, there are several ongoing and planned ground-based and satellite collaborations aimed at understanding the electromagnetic coupling between magnetospheric processes (whistler mode chorus and ECH waves) and PsA seen on the ground. This special section focuses on observational (ground-based/satellites), theoretical, and modeling aspects of PsA and related phenomena in the magnetosphere.
