Complexity analyses of geomagnetic and solar activity indices time series [PDF]
Scientific ReportsThe universal properties of the geomagnetic/solar indices critically describe their time series’ dynamics. Here, we investigate the complexity behavior of the time series of the geomagnetic and solar activity indices Kp, DST, Ap, F10.7, $$\hbox {Lyman}_{\

On the Saturation (or Not) of Geomagnetic Indices
Frontiers in Astronomy and Space Sciences, 2021 Most geomagnetic indices are associated with processes internal to the magnetosphere-ionosphere system: convection, magnetosphere-ionosphere current systems, particle pressure, ULF wave activity, etc.

Magnetic local time dependence of geomagnetic disturbances contributing to the AU and AL indices [PDF]
Annales Geophysicae, 2011 The Auroral Electrojet (AE) indices, which are composed of four indices (AU, AL, AE, and AO), are calculated from the geomagnetic field data obtained at 12 geomagnetic observatories that are located in geomagnetic latitude (GMLAT) of 61.7°–70°.

Harvestable Metadata Services Development: Analysis of Use Cases from the World Data System
Data Science Journal, 2023 Minimally, a research data repository exists to make a collection of data assets available to potential users. If a dataset cannot be discovered and found, it cannot be reused (Garnett et al. 2017).

Dynamics of Electron Flux in the Slot Region and Geomagnetic Activity
Space Weather, 2021 The slot region between the radiation belts in the magnetosphere is statistically less populated by the energetic electrons, which makes it attractive in the design considerations of the satellite missions.

Reconstruction of Geomagnetic Event as Observed in Northern Adriatic Region and Its Correlation with GPS Single-frequency Positioning Deviations [PDF]
TransNav, 2020 Space weather effects are generally recognized as causes of degradation of satellite positioning, navigation and timing (PNT) services. We analyze GPS position estimation error during a geomagnetic storm, focusing on manifestations of geomagnetic ...
