“…Afterwards, the primary cosmic ray continues to move towards Earth surface and interacts with the Earth atmospheric nuclei and produces the secondaries including muons and neutrons. Therefore, any change in atmospheric condition such as pressure or temperature can influence the observed cosmic ray flux at detector level [1,2]. These atmospheric effects on cosmic rays are known from several decades.…”

“…These atmospheric effects on cosmic rays are known from several decades. There are several studies by various experiments for studying the effects of atmospheric pressure (barometric effect) [3,4] and temperature [1,5] on cosmic rays, which shows that these effects can produce the significant modulations in the cosmic ray flux at detector level. Hence, the correction of these effects becomes necessary for doing the precision measurements.…”

A large area (560 m 2 ) muon telescope in the GRAPES-3 experiment at Ooty, India records muon intensity at high cutoff rigidities (R ) varies from 14-32 GV along 169 independent directions spanning a field of view of 2.3 sr. The threshold energy of the recorded muons is sec( ) GeV along a direction with a zenith angle ( ) and with the average angular accuracy of ∼4 . The directional capabilities of the muon telescope are exploited for studying the effect of atmospheric pressure on the muon flux as a function of R . It is observed that the barometric coefficients relationship with logarithmic R can be well described by second order polynomial function with a high Spearman Rank correlation coefficient of 0.99.
