Abstract

Abstract: Investigation of variations in the intensity of cosmic ray muon bundles detected at the ground level with the coordinate-tracking detector DECOR over a long period of observations is considered. It has been found that the measured intensity of the events exhibits clear seasonal variations, repeated every year of observations. These variations are caused by changes in atmospheric conditions. Correlations of the intensity of muon bundles with atmospheric pressure, mean air temperature and the altitude of the fixed residual atmospheric pressure levels have been analyzed.
