| Abstract: | We report the results of the application of our approach to study the behavior of solar activity in the past, where: When reconstructing the variations of solar activity, geomagnetic parameters, and the interplanetary magnetic field in the past we select a sequence of increasing time scales, which can be naturally represented by the potentials of available observational data. We select a total of four time scales: 150–200 years, 400 years, 1000 years, and 10000 years. When constructing the series of each successive (in terms of length) time scale we use the data of the previous time scale as reference data. We abandon, where possible, the series of traditional statistical parameters in favor of the series of physical parameters. When deriving the relations between any parameters of solar activity, geomagnetic disturbance, and the interplanetary magnetic field, we take into account the differential nature of relations on different time scales. To this end, we use the earlier proposed MSR and DPS methods. To verify the resulting reconstructions, we use the “principle of witnesses”, which uses independent (in some cases, indirect) information as initial data. |
