Popis:	Abstract Plasmaspheric hiss, a whistler‐mode emission confined in the high‐density plasmasphere, is of great interest to the space community attributed to its important role in inner magnetospheric dynamics. Their frequency‐time structures provide crucial evidence for understanding the wave origin. In this work, based on ∼7‐year Van Allen Probes data, we statistically studied the frequency‐drifting plasmaspheric hiss characterized by an increasing lower cutoff frequency over a timescale exceeding 1 hr. Frequency‐drifting hiss waves predominantly occur at 3
