Aims & scope

EGU Letters (EL) is a virtual scientific highlight magazine for articles reporting exceptionally important results and major advances in geoscientific research that are of high general interest to the entire geoscientific community and/or to the broader public & media.

Articles included in EL are written in a concise and engaging style. They undergo full peer review and publication as a letter style article in one of the EGU interactive open-access journals. Their inclusion in EL depends upon recommendation by the chief/executive editors of the interactive journal and approval by the interdisciplinary editorial board of the virtual magazine.

Read more about EGU Letters, the characteristics, and the editorial handling.
