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…
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…
Tests of Sunspot Number Sequences: 2. Using Geomagnetic and Auroral Data
Mike Lockwood, Mathew J. Owens, Luke A Barnard +3
We compare four sunspot-number data sequences against geomagnetic and terrestrial auroral observations. The comparisons are made for the original SIDC composite of Wolf-Zurich-Inte…
An Assessment of Sunspot Number Data Composites over 1845-2014
Mike Lockwood, Mathew J. Owens, Luke A. Barnard +1
New sunspot data composites, some of which are radically different in the character of their long-term variation, are evaluated over the interval 1845-2014. The method commonly use…
