- Abstract
- The integral local muon density spectra (LMDS) of EAS at large zenith angles were reconstructed on the basis of the DECOR experimental data on muon bundles detected in a long-term measurement series from 03.05.2012 to 04.07.2023. The results were obtained for two threshold muon density values of 0.015 and 0.068 particles/m, corresponding to the detection of bundles with a multiplicity of at least 3 and at least 5 muons in the detector. At zenith angles less than 80°, the zenith-angle dependence of LMDS is well described by a power function of the zenith angle cosine. However, with a further increase in the zenith angle, this dependence changes significantly, and at angles of 87–88°, the measured values exceed the specified simple extrapolation by about an order of magnitude. This is due to the inapplicability of the flat atmosphere approximation at such angles. A simple formula has been obtained that takes into account the curvature of the Earth's atmosphere.
