The First Four Ground-Level Enhancements in the 1940s: Investigation, Digitisation, and Analysis of Forgotten Data
Hisashi Hayakawa, Stepan Poluianov, Sergey Koldobskiy +4
Intense solar eruptions occasionally accelerate solar energetic particles (SEPs) and can trigger ground-level enhancements (GLEs). Among the 77 known GLEs, the first four GLEs, #1…
High-altitude polar NM with the new DAQ system as a tool to study details of the cosmic-ray induced nucleonic cascade
Markus Similä, Ilya Usoskin, Stepan Poluianov +3
A neutron monitor (NM) is, since the 1950s, a standard ground-based detector whose count rate reflects cosmic-ray variability. The worldwide network of NMs forms a rough spectromet…
A New Full 3-D Model of Cosmogenic Tritium H Production in the Atmosphere (CRAC:3H)
S. V. Poluianov, G. A. Kovaltsov, I. G. Usoskin
A new model of cosmogenic tritium (H) production in the atmosphere is presented. The model belongs to the CRAC (Cosmic-Ray Atmospheric Cascade) family and is named as CRAC:3H.…
The mini-neutron monitor: A new approach in neutron monitor design
Du Toit Strauss, Stepan Poluianov, Cobus van der Merwe +15
The near-Earth cosmic ray flux has been monitored for more than 70 years by a network of ground-based neutron monitors (NMs). With the ever-increasing importance of quantifying the…
FORESAIL-1 cubesat mission to measure radiation belt losses and demonstrate de-orbiting
FORESAIL collaboration, M. Palmroth, J. Praks +57
Today, the near-Earth space is facing a paradigm change as the number of new spacecraft is literally sky-rocketing. Increasing numbers of small satellites threaten the sustainable…
Solar energetic particles and galactic cosmic rays over millions of years as inferred from data on cosmogenic Al in lunar samples
S. Poluianov, G. A. Kovaltsov, I. G. Usoskin
Aims. Lunar soil and rocks are not protected by a magnetic field or an atmosphere and are continuously irradiated by energetic particles that can produce cosmogenic radioisotopes d…
GLE and Sub-GLE Redefinition in the Light of High-Altitude Polar Neutron Monitors
S. V. Poluianov, I. G. Usoskin, A. L. Mishev +2
The conventional definition of ground-level enhancement (GLE) events requires a detection of solar energetic particles (SEP) by at least two differently located neutron monitors. S…
Production of cosmogenic isotopes 7Be, 10Be, 14C, 22Na and 36Cl in the atmosphere: Altitudinal profiles of yield functions
Stepan Poluianov, Gennady A. Kovaltsov, Alexander L. Mishev +1
New consistent and precise computations of the production of five cosmogenic radio-isotopes, 7Be, 10Be, 14C, 22Na and 36Cl, in the Earth's atmosphere by cosmic rays are presented i…
Critical Analysis of a Hypothesis of the Planetary Tidal Influence on Solar Activity
Stepan Poluianov, Ilya Usoskin
The present work is a critical revision of the hypothesis of the planetary tidal influence on solar activity published by Abreu et al. (Astron. Astrophys. 548, A88, 2012; called A1…
