Record neutron monitor counting rates from galactic cosmic rays

, 2013
Neutron monitors have recorded the flux of high‐energy Galactic cosmic rays for more than half a century. During the recent, prolonged, deep minimum in solar activity, many sources indicate that modulated Galactic cosmic rays have attained new Space Age ...

Interpolating Electron Diffusion Coefficients in Earth's Radiation Belts: A Neural Network Model Inspired by Video Frame Interpolation

Space Weather, Volume 23, Issue 11, November 2025.
Abstract Many numerical models have been built to uncover the physical mechanisms governing radiation belt dynamics and enable real‐time forecasting. The diffusion coefficient, as a critical input for these models, is usually obtained through linear interpolation from precomputed diffusion coefficient libraries.

SAS-2 observations of the galactic gamma radiation from the Vela region [PDF]

Data from a scan of the galactic plane by the SAS-2 high energy gamma ray experiment in the region 250 deg l2 290 deg show a statistically-significant excess over the general radiation from the galactic plane for gamma radiation of energy 100 MeV in ...

Spatiotemporal Variations in Surface Air 7Be Concentrations Over the Antarctic Regions of the Indian Sector

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 20, 28 October 2025.
Abstract This study examined spatiotemporal variations in Beryllium‐7 (7Be) concentrations measured in surface air in high‐latitude regions of the Indian sector of the Southern Ocean, including two Japanese coastal stations. The sites included Syowa Station (69°00′S, 39°35′E) and site S17 (69°02′S, 40°05′E) on the coastal Antarctic ice sheet ...

Mapping Large‐Scale Deep Soil Moisture Variations Using Ambient Seismic Noise

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.
Abstract Soil moisture is an essential ecosystem resource and a major control of the Earth's hydrological cycle and energy balance, closely interacting with the climate system. However, investigating deep soil moisture dynamics at large scales presents significant challenges due to the sparse distribution and limited spatial representativeness of in ...

Small-scale Cosmic-Ray Anisotropy Observed by the GRAPES-3 Experiment at TeV Energies

The Astrophysical Journal
GRAPES-3 is a mid-altitude (2200 m) and near-equatorial (11.°4N) air shower array, overlapping in its field of view for cosmic-ray observations with experiments that are located in the Northern and Southern Hemispheres. We analyze a sample of 3.7 × 10 ^9
