“…The mean pressure coefficient was calculated to -0.710 ± 0.005 % /hPa . Which expectedly comes very similar for all the detectors with 0.11 rms.The measurements show fairly good agreement with previous reports [6,7]. After correcting for atmospheric effects, the reduction in daily variations can be seen easily in Fig.…”

The GRAPES-3 experiment, a high density extensive air shower (EAS) array located at Ooty, India is designed for high precision measurements of cosmic ray energy spectrum and nuclear composition in energy range of 10 13 -10 16 eV . It consists of tightly packed 1 m 2 area 400 plastic scintillation detectors covering an effective area of 25,000 m 2 . The trigger rate and particle density measured by EAS array shows strong correlation with the atmospheric parameters such as the pressure, and temperature. By employing linear regression, and Fast Fourier Transform techniques, the pressure and temperature coefficients for the dependence of trigger rate and particle density, respectively were obtained. Thereafter, by applying corrections for these effects the contribution of atmospheric effects was largely eliminated in the EAS data. These corrections are expected to result in a better measurement of EAS parameters which will be presented during the conference.

“…Many studies were carried out to find the pressure coefficient of extensive air showers (EAS). Daudin [7] shows the pressure coefficient value is (-0.75±0.01)% /mb for EAS of primary energy ≈10 14 eV primary energies EAS. In section 3.2, we have studied the atmospheric pressure effect on GRAPES-3 EAS data.…”

“…The mean pressure coefficients were calculated for all scintillation detectors which is found to be (-0.68 ± 0.01) % hPa −1 with 0.1 % hPa −1 rms as shown in Fig. 2, very similar to the earlier reports [7,8]. However, there is no lag observed between PD and pressure which is expected because pressure effect is independent of detector properties and therefore, all the detectors pressure coefficients are observed to be very similar which is reflected by narrow spread in coefficients.…”
