The muon charge asymmetry and the directional distribution of thunderstorm events observed by the GRAPES-3 muon telescope
B. Hariharan, S. K. Gupta, Y. Hayashi +12
The electric fields inside thunderstorms can significantly modify the intensity of secondary cosmic ray muons at the ground level, producing measurable variations in their intensit…
Monitoring the upper atmospheric temperature and interplanetary magnetic field with the GRAPES-3 muon telescope
S. Paul, K. P. Arunbabu, M. Chakraborty +17
We study the influence of variations in the upper atmospheric temperature and interplanetary magnetic field on the cosmic ray induced atmospheric muon flux measured by the GRAPES-3…
An automated algorithmic method to mitigate long-term variations in the efficiency of the GRAPES-3 muon telescope
S. Paul, K. P. Arunbabu, M. Chakraborty +26
The GRAPES-3 large area muon telescope with its sixteen independent modules records the high energy (>1 GeV) muons continuously over 2.3 sr of the sky. However, the recorded muon r…
Dependence of the estimated electric potential in thunderstorms observed at GRAPES-3 on the hadronic interaction generators used in simulations
B. Hariharan, S. K. Gupta, Y. Hayashi +13
A potential difference of 1.3 Giga-Volts (GV) was inferred across a thundercloud using data from the GRAPES-3 muon telescope (G3MT) [1]. This was the first-ever estimation of gigav…
Ideas and Requirements for the Global Cosmic-Ray Observatory (GCOS)
Markus Ahlers, Ingo Allekotte, Jaime Alvarez-Muniz +136
After a successful kick-off meeting in 2021. two workshops in 2022 and 2023 on the future Global Cosmic-Ray Observatory (GCOS) focused mainly on a straw man design of the detector…
