Ground-based Observations of Temporal Variation of Cosmic Ray Spectrum during Forbush Decreases
W. Mitthumsiri, D. Ruffolo, K. Munakata +29
Observations of temporary Forbush decreases (FDs) in the Galactic cosmic ray (GCR) flux due to passage of solar storms are useful for space weather studies and alerts. Here we intr…
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…
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…
Analysis of cosmic rays' atmospheric effects and their relationships to cutoff rigidity and zenith angle using Global Muon Detector Network data
R. R. S. Mendonça, C. Wang, C. R. Braga +19
Cosmic rays are charged particles whose flux observed at Earth shows temporal variations related to space weather phenomena and may be an important tool to study them. The cosmic r…
Cosmic ray short burst observed with the Global Muon Detector Network (GMDN) on June 22, 2015
K. Munakata, M. Kozai, P. Evenson +14
We analyze the short cosmic ray intensity increase ("cosmic ray burst": CRB) on June 22, 2015 utilizing a global network of muon detectors and derive the global anisotropy of cosmi…
