Analysis of the small-scale cosmic ray fluctuations spectrum inferred from ground-based cosmic ray observation data.

The relationships between the spectral characteristics of cosmic ray intensity and interplanetary magnetic field are studied theoretically using the spectral cosmic ray intensity characteristics inferred from ground-based observation data. The mean spectral characteristics of interplanetary magnetic field are calculated. The results of the calculations are compared with observational results. The results of analyzing the cosmic ray fluctuations during various periods and at various stations are described.
