Overview of Anomality Measure Application for Estimating Geomagnetic Activity

Regression Derivatives and Their Application in the Study of Magnetic Storms

“…The result of this work in theoretical terms should be considered the construction for the original record f = f (t) and the property P specified relative to it, of interest to the researcher, a two-dimensional function µP f = µP f (t, s), expressing on the scale of the segment [−1, 1] in at a given node t, a measure of the manifestation of property P on a record f at a given scale of its consideration s ≥ 0 [Agayan et al, 2016[Agayan et al, , 2021b[Agayan et al, , 2020Oshchenko et al, 2020;Soloviev et al, 2017].…”

“…For example, using the local indicators, the analysis of St. Patrick's Day Storm was performed [Gvishiani et al, 2016b]. The developed anomalousness measure [Soloviev et al, 2017] was applied to geomagnetic activity studies [Agayan et al, 2016], in Sq variation analysis [Soloviev et al, 2019], and in the global geomagnetic storm analysis at different latitudes during different phases [Oshchenko et al, 2020]. The preceding research, also related to the DMA apparatus, was intended to demonstrate the possibilities of activity measures in the analysis of the structure of a magnetic storm [Agayan et al, 2021b].…”
