In all of these categories, only new and original contents will be considered for publication. Express Letters provide authors with a way to rapidly publish brief reports of high-impact results. Frontier Letters cover frontier research in various fields in Earth and Planetary Sciences, and can be contributed only through an invitation by the Editor-in-Chief. Technical Reports present technical aspects of research in related fields. EPS also provides a venue for topical special issues based on conferences, research projects, and other research initiatives.
