Baillie, Orsi; Thomson, Alan; Nagy, Tamás; Dawson, Ewan; Kelly, Gemma; Wesztergom, Victor; Clarke, Ellen. 2013 Extreme value statistics applied to geoelectric activity in Europe ... a first look. [Poster] In: European Space Weather Week 10, Antwerp, Belgium, 18-22 Nov 2013. (Unpublished)
The Nagycenk observatory now has more than 50 years of geoelectric (or telluric) field data. In this poster we apply the
technique of extreme value statistics to these data to determine the 1 in 100 and 1 in 200 year peak values of the surface
electric field. In 2012, geoelectric monitoring sites were installed at each of the three UK geomagnetic observatories. The
data now being recorded at these sites is also analysed in comparison with the Nagycenk data, to provide an initial look at the
wider European scale view of surface geoelectric fields.
