Abstract
Investigations of the physical behaviour of the cosmic ray variations in various time scales are an important aspect in cosmic ray astronomy. The modulation of cosmic rays is an important tool for investigating disturbed behaviour in the heliosphere with longer time scales related to solar activities, while shorter time variations can be associated with Earth's atmospheric phenomena. The atmospheric temperature and pressure effect on count rates of DEASA detectors for 7 hours daily spanning 170 days from January to June 2022 is reported. The detectors are calibrated and their efficiencies have been plotted. Temperature and pressure profile at DEASA are studied. Then the cosmic ray intensities at one detector is studied to calculate the barometric and temperature coefficients. Finally the relative CR intensities of D6 detector is plotted with relative temperature and pressure in a time series plot. The graphs verify the expected behaviour of detector flux with atmospheric parameters and comparative study with other array data is reported.
