Atmospheric electricity is a long-established subject, with the discovery of
the atmospheric electric field away from thunderstorms and the identification of lightning as electricity both dating from the mid-18th
century (Aplin et al., 2008). Systematisation of atmospheric electricity
measurements began with the establishment of many geophysical observatories
as part of the “magnetic crusade” and the professionalisation of science in the 1830s (e.g. Macdonald, 2018). Although this special issue is focused
on the contributions made by observatories, historic atmospheric electricity
measurements can be valuable for contemporary science and technology. For
example, they can contribute to climatological studies of convective storms
(Valdivieso et al., 2019) as well as new insights into space weather (e.g.
Aplin and Harrison, 2014) and air pollution (Harrison and Aplin, 2002).
Beyond the observatory network, there are numerous other accounts of
historical atmospheric electricity observations from across the world. Most
are short-lived, some predate the establishment of observatories, and others
were made by the amateur scientists of the day. These have been tabulated
and are available online (
Some of the observatories with long datasets or that were otherwise historically significant have already been described; for example, the longest known atmospheric electric field time series is from Kew Observatory near London, UK, with a historical account by Macdonald (2018) and scientific analysis by e.g. Harrison (2006). During a recent project, GloCAEM, which produced a worldwide atmospheric electric field database (Nicoll et al., 2019), it became apparent that historic data were available and in principle submittable to the database, but that the sites of and background to these measurements had not been fully described. Historic datasets and observatories are also regularly discussed at meetings of the international COST action CA15211, a European atmospheric electricity networking project.
This special issue has been motivated by scientists in the atmospheric
electricity community requesting an opportunity to explain the scientific
and historical context of their data series. It encourages, but is not
limited to, submissions on historical atmospheric electricity measurements focused on the observatories participating in the GloCAEM
project and COST action. Broader submissions discussing other atmospheric
electricity observatories are also welcomed, with no requirement to be
involved with either project. It is anticipated that submissions will
describe the history of the observing site and the role of key individuals. The atmospheric electrical observations and techniques should be discussed
as well as any other relevant measurements, such as magnetic or
meteorological, at the site. Significant events during the observing period
and their effect on the data can also be described. The data from the
observatory should be linked to or cited if available elsewhere, and if not,
some brief data summaries may be included. Accounts of other observatories,
not measuring atmospheric electrical quantities, should be submitted to the
parallel special issue (
