Complexity analyses of geomagnetic and solar activity indices time series. [PDF]
Sci RepThe 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.

Space Weather, 2022 The responses of thermospheric densities to geomagnetic activity indices and Joule heating are analyzed during 265 geomagnetic storms and can be used to calibrate the model NRLMSISE‐00 with neutral mass density observed at 400 km based on the CHAMP ...

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).

Geomatics, Natural Hazards & Risk, 2023 This paper reports three methods of researching the geoelectric index (GEI) based on the ratio between the variation amplitude of geoelectric field on an index calculation day and that on a magnetically quiet day, and uses the three methods to process ...

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.

Geophysical Monograph Series, Page i-xiv., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Impact of ICME- and SIR/CIR-Driven Geomagnetic Storms on the Ionosphere over Hungary
Atmosphere, 2023 We investigate the differences between the effects of geomagnetic storms due to Interplanetary Coronal Mass Ejections (ICME) and due to Stream Interaction Regions or Corotating Interaction Regions (SIR/CIR) on the ionospheric F2-layer during the maximum ...

Solar flares and variation of local geomagnetic field: Measurements by the Huancayo Observatory over 2001-2010 [PDF]
Serbian Astronomical Journal, 2017 We study the local variation of the geomagnetic field measured by the Huancayo Geomagnetic Observatory, Peru, during 2001-2010. Initially, we sought to relate the SFI values, stored daily in the NOAA's National Geophysical Data Center, with the ...
