Editorial This is a new volume of Earth, Planets and Space (EPS) with an open access-style publishing model under SpringerOpen. EPS had a conventional style publication with Terrapub (Tokyo Japan) from 1998 until 2013 as a continuation of the two journals, the Journal of Geomagnetism and Geoelectricity (1949 to 1997) and the Journal of Physics of the Earth (1952 to 1997). We hope that our new open access model as of 2014 will have a greater impact. The scope of EPS is broad, covering earth and planetary sciences, and in particular geomagnetism, aeronomy, space science, seismology, volcanology, geodesy, and planetary science. EPS also covers articles in new and interdisciplinary subjects, including technical topics. We have established four categories for articles: full papers, letters, frontier letters, and technical reports. The full papers are research articles with no page limit. The letters are short papers of eight pages or less in the final PDF version. The frontier letters are letter articles, which are invited by the Editor in Chief, while the technical reports are for the presentations of software tools, experimental or computational methods, or hardware designs.
