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…
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…
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…
