Tensor anisotropy of cosmic rays by data of neutron monitors and muon telescopes

Abstract

The long-term data of neutron monitors of the world-wide network have been processed using the global survey method. In addition to the symmetrical diurnal variation, the semidiurnal and antisymmetric diurnal variations reflecting the availability of tensor anisotropy have been stood out. Results are analyzed jointly with the data of muon component from the st. Nagoya for the time period 1971 to 2012 and physical mechanisms responsible for anisotropy are discussed.
