Cosmic ray north-south anisotropy: rigidity spectrum and solar cycle variations observed by ground-based muon detectors

M. Kozai, Y. Hayashi, K. Fujii +9

The north-south (NS) anisotropy of galactic cosmic rays (GCRs) is dominated by a diamagnetic drift flow of GCRs in the interplanetary magnetic field (IMF), allowing us to derive ke…
