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…
Space Climate and Space Weather over the past 400 years: 1. The Power input to the Magnetosphere
Mike Lockwood, Mathew J. Owens, Luke A. Barnard +2
Using information on geomagnetic activity, sunspot numbers and cosmogenic isotopes, supported by historic eclipse images and in conjunction with models, it has been possible to rec…
