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…
Global analysis of the extended cosmic-ray decreases observed with world-wide networks of neutron monitors and muon detectors; temporal variation of the rigidity spectrum and its implication
K. Munakata, Y. Hayashi, M. Kozai +20
This paper presents the global analysis of two extended decreases of the galactic cosmic ray intensity observed by world-wide networks of ground-based detectors in 2012. This analy…
Variations in the Inferred Cosmic-Ray Spectral Index as Measured by Neutron Monitors in Antarctica
Pradiphat Muangha, David Ruffolo, Alejandro Sáiz +7
A technique has recently been developed for tracking short-term spectral variations in Galactic cosmic rays (GCRs) using data from a single neutron monitor (NM), by collecting hist…
Solar Magnetic Polarity Effect on Neutron Monitor Count Rates: Comparing Latitude Surveys and Antarctic Stations
K. Poopakun, W. Nuntiyakul, S. Khamphakdee +11
The Galactic cosmic ray spectrum manifests pronounced variations over the 11-year sunspot cycle and more subtle variations over the 22-year solar magnetic cycle. An important tool…
Large amplitude bidirectional anisotropy of cosmic-ray intensity observed with world-wide networks of ground-based neutron monitors and muon detectors in November, 2021
K. Munakata, M. Kozai, C. Kato +24
We analyze the cosmic-ray variations during a significant Forbush decrease observed with world-wide networks of ground-based neutron monitors and muon detectors during November 3-5…
A Peculiar ICME Event in August 2018 Observed with the Global Muon Detector Network
W. Kihara, K. Munakata, C. Kato +20
We demonstrate that global observations of high-energy cosmic rays contribute to understanding unique characteristics of a large-scale magnetic flux rope causing a magnetic storm i…
