Near‐Earth Solar Wind Speed of Fast Coronal Mass Ejections

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Using solar wind and ground magnetometer data for solar cycles 23–25, extreme‐value power‐law models are developed that quantify relationships between near‐Earth solar wind speed and Sun‐to‐Earth transit times of interplanetary coronal mass ejections (ICMEs).

Latitude Survey of Neutrons and Muons to Determine Cosmic Ray Neutron Sensing Yield Functions

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Cosmic Ray Neutron Sensing (CRNS) is a ground‐based technique that utilizes epithermal neutron measurements as a proxy for environmental hydrogen content. Similarly to other ground‐based cosmic ray detectors (e.g., neutron monitors), CRNS detectors are affected by the solar cycle and space weather events.

Near‐Earth Cosmic Ray Modulation Index ϕ and Neutron Monitor Cutoff Rigidities at Hourly Cadence: Toward an Improved Monitoring of Solar‐Terrestrial Radiation Environment, Space Weather, and Space Climate

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Cosmic rays (CRs) are energetic particles originating from galactic and extragalactic sources. When arriving into the solar system and the Sun's heliosphere, they are diverted and modulated by the magnetic activity of the Sun. This modulation can be quantified by the modulation parameter ϕ $\phi $ determined with the Force‐field approximation (
