Journal ArticleDOI
Two solar proton fluence models based on ground level enhancement observations
Osku Raukunen,Rami Vainio,A. J. Tylka,William F. Dietrich,Piers Jiggens,D. Heynderickx,Mark Dierckxsens,Norma Crosby,Urs Ganse,Robert Siipola +9 more
TL;DR: In this paper, the authors present two new statistical models of high energy solar proton fluences based on ground level enhancement (GLE) observations during solar cycles 19-24 using a four parameter double power law function (known as the Band function) fits to integral GLE fluence spectra in rigidity.
Journal ArticleDOI

Journal ArticleDOI
ULF foreshock under radial IMF: THEMIS observations and global kinetic simulation Vlasiator results compared
Minna Palmroth,Martin Archer,Martin Archer,Rami Vainio,Heli Hietala,Yann Pfau-Kempf,Yann Pfau-Kempf,Sanni Hoilijoki,Sanni Hoilijoki,Otto A. Hannuksela,Otto A. Hannuksela,Urs Ganse,A. Sandroos,S. von Alfthan,Jonathan Eastwood +14 more
TL;DR: In this article, the authors investigate the ULF foreshock under a quasi-radial IMF with Vlasiator, which is a newly developed global hybrid-Vlasov simulation solving the Vlasov equation for protons, while electrons are treated as a charge neutralizing fluid.
Journal ArticleDOI
Linear Decrease in Athletic Performance During the Human Life Span.
TL;DR: Results showed an accelerated decline beyond the age of 70 in sprint, middle- and long-distance running, while in throwing and jumping disciplines the performance continued a linear decline.
Journal ArticleDOI
Mirror modes in the Earth's magnetosheath: Results from a global hybrid‐Vlasov simulation
Sanni Hoilijoki,Sanni Hoilijoki,Minna Palmroth,Brian Walsh,Yann Pfau-Kempf,Yann Pfau-Kempf,Sebastian von Alfthan,Urs Ganse,Otto A. Hannuksela,Rami Vainio +9 more
TL;DR: In this paper, the authors investigate mirror mode structures in the Earth's magnetosheath using global kinetic Vlasiator simulation, which models ion behavior through their distribution function and treats electrons as a charge-neutralizing fluid.
