Projection Mappings for the 3D Matrix of the Number of Realizations for the Interplanetary Magnetic Field

A new method for recording and analyzing variations in the structure of the interplanetary magnetic field is considered. It is based on the synthesis of 3D profiles of three mutually orthogonal projections of the matrix of the number of state realizations constructed in the GSE coordinate system. Spatial statistical moments of lower and higher orders are considered, which make it possible to separate the drift of projection centers, the variation of diffusion characteristics relative to the centroid axes, and multimodal realizations in the observation time interval. The monitoring data set is based on experimental samples from the WIND apparatus for four significant 18-day time intervals in January, August, September, and October 2024. A detailed analysis of the observed variation in the second spatial statistical moments is carried out using the cubic spline interpolation method. The high information capacity of the proposed method makes it possible to control a wide range of central spatial statistical moments realized in the system and to create secondary kinematic parameters of the processes under study. The proposed set of primary metrics for analyzing the structure of distortions based on moments from the first to the fourth order allows creating signatures for recognizing the type of observed distortions of the interplanetary magnetic field, detecting transient processes in the heliosphere generated by solar activity.
