The Geomagnetic Kp Index and Derived Indices of Geomagnetic Activity [PDF]

open access: yesSpace Weather, 2021
AbstractThe geomagnetic Kp index is one of the most extensively used indices of geomagnetic activity, both for scientific and operational purposes. This article reviews the properties of the Kp index and provides a reference for users of the Kp index and associated data products as derived and distributed by the GFZ German Research Centre for ...

Research on Ground Calibration Technology for Geomagnetism Sensors

open access: yesMATEC Web of Conferences, 2018
The measurements of geomagnetism sensors are often affected by self-factors, install-factors and environment factors, therefore they often exist error and cause measurement accuracy reduction.

Simultaneous observations of ESF irregularities over Indian region using radar and GPS [PDF]

open access: yesAnnales Geophysicae, 2008
In this paper, we present simultaneous observations of temporal and spatial variability of total electron content (TEC) and GPS amplitude scintillations on L1 frequency (1.575 GHz) during the time of equatorial spread F (ESF) while the MST radar (53 ...

Applications for CryoSat-2 satellite magnetic data in studies of Earth’s core field variations

open access: yesEarth, Planets and Space, 2021
We use 20 years of continuous magnetic field measurements from the Ørsted, CHAMP and Swarm satellite missions, supplemented by calibrated platform magnetometer data from the CryoSat-2 satellite, to study time variations of the Earth’s core field at ...

The geomagnetic and geoelectric response to the May 2024 geomagnetic storm in the United Kingdom

open access: yesFrontiers in Astronomy and Space Sciences
The “Gannon” geomagnetic storm of 10 −12 May 2024 was the first extreme storm of the solar cycle 25 and the largest storm in more than 20years. The auroral electrojet, driven by a strong negative interplanetary magnetic field exceeding −50nT, moved ...

Climate Change and Monsoon: Looking Into Its Antecedents

open access: yesSAGE Open, 2019
Climate change is a tricky issue. The Indian subcontinent has experienced many regional and local climatic changes in its past. There is overwhelming geological evidence of global climatic changes which are associated with extinctions and new life form ...

Characteristics of storm time ion composition in the near-Earth plasma sheet using Geotail and RBSP measurements

open access: yesEarth, Planets and Space, 2018
Solar wind particles and ionospheric O+ ions influence the near-Earth plasma sheet and inner magnetospheric composition. We studied the behavior of H+, O+ and He+ ions (9–210 keV) for intense and moderate geomagnetic storms of solar cycle 23 and 24.
