Quasi‐Periodic EMIC Waves and Pulsating Ionospheric Perturbations Related to ULF Waves
JOURNAL OF GEOPHYSICAL RESEARCH: SPACE PHYSICS
13 september 2024
Longxing Ma, Jinbin Cao, Wenlong Liu, Linhui Tang,...

Pulsating proton auroras are often attributed to periodic proton precipitation. However, how the proton precipitation is periodically generated in ...
