Abstract:The Global atmospheric Electric Circuit (GEC) is a fundamental coupling network of the climate system connecting electrically disturbed weather regions with fair weather regions across the planet. The GEC sustains the fair weather electric field (or potential gradient, PG) which is present globally and can be measured routinely at the surface using durable instrumentation such as modern electric field mills, which are now widely deployed internationally. In contrast to lightning or magnetic fields, fair weather PG cannot be measured remotely...

2. Ground level gamma-ray and electric field enhancements during disturbed weather: Combined signatures from convective clouds, lightning and rain

Authors: Yuval Reuvenia,^a,b,c,, Yoav Yair^c, Colin Price^d, Gideon Steinitz^e

4. Atmospheric muons: experimental aspects

Authors: S. Cecchini¹ and M. Spurio^1,2

Abstract: We present a review of atmospheric muon flux and energy spectrum measurements over almost six decades of muon momentum. Sea level and underground/water/ice experiments are considered. Possible sources of systematic errors in the measurements are examined. The characteristics of underground/water muons (muons in bundle, lateral distribution, energy spectrum) are discussed. The connection between the atmospheric muon and neutrino measurements are also reported...

5.Atmospheric Muon Flux at Sea Level, Underground and Underwater

Authors: E. V. Bugaev, ¹ A. Misaki, ² V. A. Naumov, ^3,4 T. S. Sinegovskaya,³ S. I. Sinegovsky, ³ and N. Takahashi⁵

Abstract:The vertical sea-level muon spectrum at energies above 1 GeV and the muon intensities at depths up to 18 km w.e. in different rocks and in water are calculated. The results are particularly collated with a great body of the ground-level, underground, and underwater muon data. In the hadron-cascade calculations, we take into account the logarithmic growth with energy of inelastic cross sections and pion, kaon, and nucleon generation in pion-nucleus collisions. For evaluating the prompt muon contribution to the muon flux, we apply the two phenomenological approaches to the charm production problem: the recombination quark-parton model and the quark-gluon string model...

6.Monitoring temporal opacity fuctuations of large structures with muon radiography: a calibration experiment using a water tower

Authors:Kevin Jourde¹, DominiqueGibert^2,3, Jacques Marteau⁴, Jean de Bremond d’Ars², SergeGardien⁴, ClaudeGirerd⁴ & Jean-Christophe Ianigro⁴

Abstract: Usage of secondary cosmic muons to image the geological structures density distribution signifcantly developed during the past ten years. Recent applications demonstrate the method interest to monitor magma ascent and volcanic gas movements inside volcanoes. Muon radiography could be used to monitor density variations in aquifers and the critical zone in the near surface. However, the time resolution achievable by muon radiography monitoring remains poorly studied. It is biased by fuctuation sources exterior to the target, and statistically afected by the limited number of particles detected during the experiment...

7.Cosmic Ray Muon Detection using NaI Detectors and Plastic Scintillators

Authors: Chung Yau Elton Ho

Abstract: We measured the zenith angle θ distribution of cosmic ray muons at ground level using NaI detectors and plastic scintillators, and our data is consistent with the cos2 θ distribution obtained from theory and other experiments. We also discussed the pros and cons of using NaI detectors and plastic scintillators.

8. Muon Radiation Dose and Marine Megafaunal Extinction at the End-Pliocene Supernova

Authors: Adrian L. Melott¹, Fraciole Marinho², and Laura Paulucci³

Abstract: Considerable data and analisys support the detection of one or more supernovae (SNe) at a distance of about 50pc, ͠ 2.6 million years ago. This is possibly related to the extinction event around that time and is a member of a series of explosions that formed the Local Bubble in the interstellar medium. We build on previous work, and propagate the muon flux from SN-initiated cosmic rays from the surface to the debths of the ocean. We find that the radiation dose from the muons will exceed the total present surface dose from all sources at dephts up to 1 km and will persist for at least the lifetime of marine megafauna...

Authors: Yuuki Wada^iD1,2,3 , Teruaki Enoto ^{iD 2,4} ,Yoshitaka Nakamura⁵ , Yoshihiro Furuta⁶ , Takayuki Yuasa ^iD7, Kazuhiro Nakazawa^iD8 , Takeshi Morimoyo ^iD9 , Mitsuteru Sato¹⁰ , Takahiro Matsumoto, Daisuke Yonetoku ¹¹ , Tatsuya Sawano¹¹ , Hideo Sakai¹² , Masashi Kamogawa ¹³, Tomoo Ushio¹⁴, Kazuo Makishima^1,2,15 and Harufumi Tsuchiya¹⁶

Abstract: Two types of high-energy events have been detected from thunderstorms. One is ''terrestrial gamma-ray flashes'' (TGFs), sub-millisecond emissions coinciding with lightning discharges. The other is minute-lasting "gamma-ray glows". Although both phenomena are thought to originate from relativistic runaway electron avalanches in strong electric fields, the connection between them is not well understood...
