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,…
Space climate and space weather over the past 400 years: 2. Proxy indicators of geomagnetic storm and substorm
Mike Lockwood, Mathew J. Owens, Luke A. Barnard +3
Using the reconstruction of power input to the magnetosphere given in Paper 1 (arXiv:1708.04904), we reconstruct annual means of geomagnetic indices over the past 400 years to with…
