Development and Deployment of the Smart Active Ionising Radiation at Altitude (SAIRA) Instruments for Space Weather Applications

open access: yesSpace Weather, Volume 24, Issue 6, June 2026.
Abstract This paper introduces the latest generation of airborne ionising radiation monitors, developed at the Surrey Space Centre (SSC) as part of the United Kingdom's (UK's) Space Weather Instrumentation, Measurement, Modeling and Risk (SWIMMR) program.

Shock drift mechanism for Forbush decreases

open access: yesThe Astrophysical Journal, 1990
Consideration is given to the way in which Forbush decreases can arise from variable drifts in nonuniform shocks, where the variation in shock strength along the shock front causes both the shock drift distance and the energy gain to become variable.

Regional and Seasonal Effects of Geomagnetic Storms on Terrestrial Weather

open access: yesGeophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract It has long been a mystery why small Total Solar Irradiation changes have significant effects on Earth's climate. Solar cycle correlation studies abound but cannot conclusively point to a viable physical mechanism. Here, I show that geomagnetic storms have a profound terrestrial weather impact.

LEO‐DOS Absorbed Dose Observations During the May 2024 Geomagnetic Superstorm

open access: yesGeophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract The Low‐Earth Orbit Space Radiation Dosimeter (LEO‐DOS) onboard Next‐Generation Satellite II (NEXTSat‐2) measured absorbed dose rate variations during the May 2024 geomagnetic superstorm. The observations show deep storm‐time penetration of solar energetic particle (SEP) spanning L ≈ 2–10, a pronounced enhancement near L ≈ 3 consistent with ...

Reduced ERA‐I Forecasting Skill During Forbush Decreases

open access: yesGeophysical Research Letters
Correlations 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 ...

Report of Cosmic-Ray Neutron Observation in the 9th Japanese Antarctic Research Expedition 1968-1969 (Reports of the Japanese Antarctic Research Expedition)

open access: yesAntarctic Record, 1971
From February 1968 to January 1969, cosmic ray nucleonic component was observed at Syowa Station, Antarctica (69°00'S, 39°35'E), using a duplicate set of 5-NM-64 super neutron monitor with a multiplicity meter.

Theory of the Formation of Forbush Decrease in a Magnetic Cloud: Dependence of Forbush Decrease Characteristics on Magnetic Cloud Parameters

open access: yesThe Astrophysical Journal, 2019
Abstract A theory of the formation of Forbush decrease in a magnetic cloud is presented. It is found that the formation mechanism is the energy loss of cosmic rays in a magnetic cloud represented as a moving magnetic loop with a helical field.

Starving for Data: Eating Disorders Prevalence and Research Gaps in Southern Africa

open access: yesInternational Journal of Eating Disorders, Volume 59, Issue 4, Page 682-699, April 2026.
ABSTRACT Objective Studies reporting prevalence estimates of eating disorders in Southern Africa are scarce. To fill this gap, the present Research Forum reviews existing literature on the prevalence of eating disorders, including as assessed by clinical interviews, screeners, and self‐reported behaviors, among individuals in Southern Africa.

Effects of Forbush Decreases on the Global Electric Circuit

open access: yesSpace Weather
The suppression of high‐energy cosmic rays, known as Forbush decreases (FDs), represents a promising factor in influencing the global electric circuit (GEC) system.

A new method of measuring Forbush decreases [PDF]

open access: yesAstronomy & Astrophysics
Context. Forbush decreases (FDs) are short-term depressions in the galactic cosmic ray (GCR) flux and one of the common signatures of coronal mass ejections (CMEs) in the heliosphere. They often show a two-step profile, the second one associated with the CME’s magnetic structure. This second step can be described by the recently developed analytical FD
