“…A surface muon flux [10] of 2.0 ± 0.2 µ/s/cm 2 is used as reference. The uncertainties in this value take into account the uncertainty in altitude as well as possible seasonal variations of the atmospheric temperature resulting in a variation of the muon flux [16,17]. The dependance of rock density on the total flux can be seen in Fig.…”

“…For high energies, muons have not enough time to decay in the atmosphere and the correlation sign becomes positive (Dmitrieva et al, 2011). Many underground/water/ice experiments measured the correlation between temperature and high energy muon intensity.…”

“…For low energy muons, the latter effect is the dominant one, and the correlation sign between flux and temperature is negative (∆I µ ∝ −∆T ). For high energies, muons have not enough time to decay in the atmosphere and the correlation sign becomes positive (Dmitrieva et al, 2011).…”

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.

“…However, theory predicts that pressure coefficients tend to 0 with zenith angle increase, see Figure 5.1.1‐A of Dorman () for instance. In the temperature case, the theoretical coefficients tend to be more negative as the zenith angle increases; see Figures 8 and 9, and 11 and 12 of Dmitrieva et al (). In our experimental atmospheric coefficient analysis, we notice a similar behavior in both cases.…”

Analysis of Cosmic Rays' Atmospheric Effects and Their Relationships to Cutoff Rigidity and Zenith Angle Using Global Muon Detector Network Data

Cosmic rays are charged particles whose flux observed at Earth shows temporal variations related to space weather phenomena and may be an important tool to study them. The cosmic ray intensity recorded with ground-based detectors also shows temporal variations arising from atmospheric variations. In the case of muon detectors, the main atmospheric effects are related to pressure and temperature changes. In this work, we analyze both effects using data recorded by the Global Muon Detector Network, consisting of four multidirectional muon detectors at different locations, in the period between 2007 and 2016. For each Global Muon Detector Network directional channel, we obtain coefficients that describe the pressure and temperature effects. We then analyze how these coefficients can be related to the geomagnetic cutoff rigidity and zenith angle associated with cosmic ray particles observed by each channel. In the pressure effect analysis, we found that the observed barometric coefficients show a very clear logarithmic correlation with the cutoff rigidity divided by the zenith angle cosine. On the other hand, the temperature coefficients show a good logarithmic correlation with the product of the cutoff and zenith angle cosine after adding a term proportional to the sine of geographical latitude of the observation site. This additional term implies that the temperature effect measured in the Northern Hemisphere detectors is stronger than that observed in the Southern Hemisphere. The physical origin of this term and of the good correlations found in this analysis should be studied in detail in future works.
