Forecasting SEP Atmospheric and Space Radiation by Coupling UMASEP and NAIRAS Models
Space Weather, Volume 24, Issue 1, January 2026.Abstract The Nowcast of Aerospace Ionizing RAdiation System (NAIRAS) model predicts the radiation environment from the Earth's surface to free‐space. The model output provides dosimetric and particle flux quantities required to assess the hazardous radiation impacts to human health and adverse effects on vehicle electronic systems.

ATMOSPHERIC PRESSURE DEFICIENCY INSIDE THE HUT INFERRED FROM COSMIC RAYS AT SYOWA BASE
Antarctic Record, 1964 Analysis of cosmic ray neutron intensity observed at Syowa Base in 1961 shows a number of events of unusual decrease in intensity. They are not so-called Forbush decrease but apparent phenomena due to pressure deficiency under a blow of strong wind.

Forcing of Climate Variations by Mev-gev Particles [PDF]
, 1990 Changes in ionization production in the lower stratosphere by a few percent during Forbush decreases have been shown to correlate well with changes in winter tropospheric dynamics by a similar relatively small amount.

Testing the proposed link between cosmic rays and cloud cover
, 2008 A decrease in the globally averaged low level cloud cover, deduced from the ISCCP infra red data, as the cosmic ray intensity decreased during the solar cycle 22 was observed by two groups.

Solar Energetic Particle Events During May 2024 Geomagnetic Superstorm
Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.Abstract Three solar energetic particle (SEP) events originating from solar active region 13664 occurred on 10–16 May 2024, coinciding with a geomagnetic superstorm. Using data from the Geostationary Operational Environmental Satellites and Meteorological Operational satellite‐C, we investigate the energetic proton fluxes and east‐west flux ratios in ...

Cosmic rays as an indicator of the geoeffectiveness of magnetic clouds [PDF]
E3S Web of Conferences, 2019 Geomagnetic storms are initiated by organized magnetic structures of the solar wind. The intensity of magnetic storms is determined by the product of the southward component of the magnetic field and the time interval, during which the structure is ...

Impacts of Extreme Space Weather Events on September 6th, 2017 on Ionosphere and Primary Cosmic Rays
Remote Sensing, 2023 The strongest X-class solar flare (SF) event in 24th solar cycle, X9.3, occurred on 6 September 2017, accompanied by earthward-directed coronal mass ejections (CMEs).

The Astrophysical Journal, 2023 The large-scale magnetic structure of interplanetary coronal mass ejections (ICMEs) has been shown to cause decreases in the galactic cosmic ray (GCR) flux measured in situ by spacecraft, known as Forbush decreases (Fds).

Forbush Decrease: A New Perspective with Classification [PDF]
Solar Physics, 2017 Sudden short-duration decreases in cosmic ray flux, known as Forbush decreases (FDs), are mainly caused by interplanetary disturbances. A generally accepted view is that the first step of an FD is caused by a shock sheath and the second step is due to the magnetic cloud (MC) of the interplanetary coronal mass ejection (ICME).

Reduced ERA‐I Forecasting Skill During Forbush Decreases
Geophysical Research LettersCorrelations between week‐long cosmic ray flux perturbations and terrestrial cloud cover have previously been identified. Still, uncertainty persists on whether the cloud response is due to a physical link involving cosmic rays or caused by random ...
