Corrections and retractions

JWGU pursues the following policy for making corrections to its content:

  • Modification of a paper: Copernicus Publications reserves the right to replace the posted files if purely technical corrections are necessary (e.g. corrupt file or incorrect bibliographical entry). In such cases, archives and indices are informed. Under no circumstances will the content be changed.
  • Corrigendum (final-revised papers only): notification of an important error made by the author(s) or by the journal that affects the publication record or the scientific integrity of the published, peer-reviewed work or the reputation of the author or the journal. Corrigenda are represented by a formal online notice. Corrigenda have to be submitted to Copernicus Publications within 3 years from the publication date of the original journal article. Should there be reasons for publishing a second corrigendum within these 3 years, the first one will be substituted by a single new corrigendum containing all relevant corrections.
  • Corrections to supplements can only be made in exceptional cases (e.g. major errors that compromise the conclusion of the study). The availability of new data is not a reason for the revision of a posted supplement. A supplement is an integral part of the manuscript in discussion or the journal article, and hence part of the record.
  • Withdrawal after discussion: authors of preprints that are not accepted for further review after discussion or where a revised manuscript was not accepted for final journal publication can request a withdrawal. The preprint stays online but the reader is notified about the withdrawal.
  • Retraction: authors or, in specific cases, editors can decide to formally withdraw a published journal article. The article stays online but the reader is notified about the retraction. Such retractions are most often accompanied by an editorial note explaining the background.
  • Marked as fraud: in the unlikely case that Copernicus Publications is notified that a posted manuscript in discussion or a published journal article turns out to be a fraud, the paper stays online but is formally withdrawn. The reader is notified about the status and fraud papers are always accompanied by an editorial note pointing out the malpractice.
