Estimation of Global Increase of Radiation Dose Rates During the Ground Level Enhancement on 11–12 November 2025 Using WASAVIES

Space Weather, Volume 24, Issue 4, April 2026.
Abstract WArning System for AVIation Exposure to Solar energetic particles (WASAVIES) is a physics‐based nowcasting system designed to support warning operations for aviation exposure to solar energetic particles (SEPs) by providing near‐real‐time global SEP dose‐rate estimates.

Real-time monitoring of the rigidity spectrum of large Forbush decreases in May and October 2024 with the paired neutron monitor and muon detector at the Antarctic Syowa Station

Earth, Planets and Space
Large Forbush decreases (FDs) in the Galactic cosmic ray flux were observed by the paired neutron monitor (SNM) and the vertical channel of the muon detector (SMDV) at the Antarctic Syowa Station in May and October, 2024.

Heart Rate Variations During Two Historic Geomagnetic Storms: October and November 2003

Atmosphere
The investigation of the two phenomena of Space Weather, i.e., Forbush decreases in the cosmic ray intensity and geomagnetic storms, is a highly developing field of modern scientific research, since these two phenomena can affect not only technological ...

Cosmic rays, cloud condensation nuclei and clouds – a reassessment using MODIS data [PDF]

Atmospheric Chemistry and Physics, 2008
The response of clouds to sudden decreases in the flux of galactic cosmic rays (GCR) – Forbush decrease events – has been investigated using cloud products from the space-borne MODIS instrument, which has been in operation since 2000.

Does the diurnal temperature range respond to changes in the cosmic ray flux?

Environmental Research Letters, 2013
Recent studies have suggested that measurements of the diurnal temperature range (DTR) over Europe may provide evidence of a long-hypothesized link between the cosmic ray (CR) flux and cloud cover.

Derivative-Aligned Anticipation of Forbush Decreases from Entropy and Fractal Markers

The Open Journal of Astrophysics
We develop a feature-based framework to anticipate Forbush decreases (FDs) in one-minute neutron-monitor records by tracking sliding-window invariants from information theory, scaling, and geometry.

Distribution of tensor anisotropy of cosmic rays near the neutral current sheet

Solar-Terrestrial Physics, 2017
We analyze time profiles of isotropic intensity, components of vector and tensor anisotropies of cos-mic rays (CR) when Earth crosses the neutral sheet of the interplanetary magnetic field (IMF) in solar activity cycles 23–24.

Measurements of Forbush Decrease Events at the Center of the South Atlantic Magnetic Anomaly With Muon Detectors

Space Weather
We present the construction and validation of a low‐cost muon detector in Paraguay, located at the center of the South Atlantic Magnetic Anomaly (SAMA), where the geomagnetic cutoff rigidity R is 9.63 GV.

Forbush-decreases in 19th solar cycle

Journal of Physics: Conference Series, 2013
The 19th solar cycle was characterized by abnormally high solar activity; unfortunately, the possibilities of observing it were limited. Ground-based observations of cosmic rays and geomagnetic activity are among the few types of continuous measurements that allow statements about the events of 19th cycle and their comparison with events of other ...
