Description

According to the data of Moscow and Climax neutron monitors, using harmonic analysis, the characteristics of the solar-diurnal anisotropy of cosmic rays on quiet days have been obtained for a long period from 1957 to 2023. A comparison with the average daily characteristics of the equatorial component of cosmic rays vector anisotropy, obtained from the data of the worldwide neutron monitor network using the global survey method showed a good agreement between the results of the two methods. From a comparison of local and global results, estimates were obtained for the coupling coefficients of the first harmonic of the cosmic ray anisotropy for Moscow and Climax neutron monitors, and a new experimental method for calculating the coupling coefficients of individual detectors was proposed. The limitations of the local method, as well as the possibility of continuing and expanding this study, have been discussed and justified.
