A novel neural network-based approach to derive a geomagnetic baseline for robust characterization of geomagnetic indices at mid-latitude
Rungployphan Kieokaew, Veronika Haberle, Aurélie Marchaudon +2
Geomagnetic indices derived from ground magnetic measurements characterize the intensity of solar-terrestrial interaction. The \textit{Kp} index derived from multiple magnetic obse…
Semi-annual, annual and Universal Time variations in the magnetosphere and in geomagnetic activity: 4. Polar Cap motions and origins of the Universal Time effect
Mike Lockwood, Carl Haines, Luke A. Barnard +4
We use the am, an, as and the a-sigma geomagnetic indices to the explore a previously overlooked factor in magnetospheric electrodynamics, namely the inductive effect of diurnal mo…
A homogeneous aa index: 2. hemispheric asymmetries and the equinoctial variation
Mike Lockwood, Ivan D. Finch, Aude Chambodut +3
Paper 1 [Lockwood et al., 2018] generated annual means of a new version of the geomagnetic activity index which includes corrections for secular drift in the geographic coordi…
A homogeneous aa index: 1. Secular variation
Mike Lockwood, Aude Chambodut, Luke A. Barnard +3
Originally complied for 1868-1967 and subsequently continued so that it now covers 150 years, the index has become a vital resource for studying space climate change. However,…
On the Influence of the Data Sampling Interval on Computer-Derived K-Indices
Armelle Bernard, Menvielle Michel, Aude Chambodut
The K index was devised by Bartels et al. (1939) to provide an objective monitoring of irregular geomagnetic activity. The K index was then routinely used to monitor the magnetic a…
