What major advantages does the interactive scientific journal AMT offer to the authors of scientific papers?

• rapid appearance and free dissemination;
• transparent peer review;
• immediate feedback via interactive discussion within the scientific community;
• moderate article processing charges, combined with financial support options for authors lacking support of funds;
• efficient new way of publishing special issues (no "waiting for the last paper");
• liberal copyright agreement.

What major advantages does AMT offer to the readers and scientific community?

• free and rapid dissemination of novel concepts and data;
• fostering and documentation of scientific discussion;
• enhancement of scientific quality control by Interactive Public Peer Review^TM;
• enhanced information content of scientific papers by appended comments;
• promotion of scientific conciseness and completeness at the same time by including comprehensive abstracts rather than imposing strict page limits.

How are efficient distribution and permanent archiving and accessibility of AMT articles achieved by the publisher Copernicus Publications?

AMT is accessible online and free of charge. Copernicus Publications makes sure that the final journal articles of AMT as well as related preprints on EGUsphere are indexed and archived worldwide in electronic archives, search engines, and databases to guarantee their maximum dissemination and impact.

How are preprints and interactive comments archived, and are the interactive comments citable?

All preprints are archived in EGUsphere, EGU's preprint repository. Preprints therefore receive a DOI EGUSPHERE-YEAR-NUMBER. The community comments, referee comments, editor comments, and author comments posted in the interactive discussion also receive their own DOI, which allows citation of every individual interactive comment.

How does AMT ensure the quality of related preprints?

• First of all, manuscripts with a clear lack of substantial results or with excessive formal deficiencies will be sorted out rigorously in the access review.
• Even if a low-quality manuscript passed the access review and was posted as EGUsphere preprint for discussion, its deficiencies would most probably be revealed in the interactive public discussion by the referees and other interested scientists.
• The access review is meant to assure the basic scientific and technical quality of the preprints, but the opportunity for an efficient public discussion by all interested members of the scientific community is expected to enhance the actual quality control beyond the limits of the traditional peer review. Even if there are no comments from the scientific community, a full peer-review process in the traditional sense, albeit in a more transparent way, is still assured before full acceptance and publication of a paper in AMT.

What happens if a manuscript that has been posted as an EGUsphere preprint is not accepted for publication as a final paper in AMT? Can the preprint be removed?

All EGUsphere preprints remain permanently archived, citable, and publicly accessible and therefore cannot be removed. This approach has been chosen for a number of practical and conceptual reasons, and it has proven to be beneficial for scientific communication and quality assurance as explained above.

Nevertheless, we are aware that the appearance of a manuscript as preprint and subsequent non-acceptance for AMT can be inconvenient for authors. In such cases, the authors have the following options to proceed:

• Option A

  The authors can appeal to the AMT executive editors for review and revision of the editorial decision. In this case, the executive editors will carefully review the decision of the editor who originally handled the manuscript. This process will normally involve the original or additional referees and an iteration of manuscript review and revision. An appeal is recommended only if the authors are firmly convinced that the editorial decision not to accept the paper for AMT was clearly erroneous and that their manuscript clearly meets all evaluation criteria for acceptance into AMT.

• Option B

  The authors can submit a rewritten manuscript for review and discussion, and possible publication in AMT. If the editor and/or authors of a manuscript publicly discussed as EGUsphere preprint conclude that the manuscript can and should be rewritten in a way which goes beyond regular revisions (e.g., addition of substantial new results, etc.), a rewritten manuscript can at any time be submitted for independent review and discussion, and final publication in AMT.

• Option C

  The authors can submit the manuscript to an alternative journal. In many scientific journals, posting a preprint on a preprint server like EGUsphere is not regarded as a reason for exclusion from (re)submission for fully peer-reviewed publication. We expect that in the long run most if not all scientific journals will adopt this policy. In any case, there cannot be any change to the status of the EGUsphere preprint since the posting on a preprint server is independent of the unsuccessful peer review for AMT.

  Normally, even very good manuscripts can be further improved by revision. In the unlikely event that a very good manuscript cannot achieve publication in AMT, a revised and further improved version is very likely to achieve publication in an alternative journal.

Overall, we are confident that the advantages of permanent archiving outweigh the potential disadvantages. For exceptional individual cases in which this policy may be disadvantageous, we regret any potential inconvenience. Nevertheless, we hope that we have the authors' understanding and continued support in the effort to improve scientific communication and quality assurance via interactive open-access publishing.

Will EGUsphere preprints aimed at publication in AMT be visible on the AMT page?

Yes, all EGUsphere preprints aimed at publication in AMT are originally posted on EGUsphere and additionally co-listed on the AMT website as long as the peer-review process including public discussion and peer-review completion is going on. If a final revised journal article is published in AMT, the corresponding EGUsphere preprint is again co-listed there, but if the revised manuscript is rejected from AMT, the EGUsphere preprint is no longer co-listed on the AMT website.

Will rejected preprints with DOI EGUSPHERE-YEAR-NUMBER remain on EGUsphere?

Yes, just like any other document with a DOI. However, they will not show a relation to the journal for which it was intended since its citation is EGUSPHERE-YEAR-NUMBER. Therefore, after rejection, the EGUsphere preprint will no longer be listed on the AMT website.

I am aiming to resubmit. Can a manuscript that was previously posted on EGUsphere be resubmitted?

Manuscripts should only be resubmitted after rejection if they were significantly enhanced and substantially revised to compensate the weaknesses reported by reviewers in the first instance.

A preprint targeting peer review in an EGU journal is already posted on another preprint server.

How should authors proceed?

The EGUsphere guidelines state that "it is inappropriate for an author to submit preprints describing essentially the same research to more than one server to be posted simultaneously". Hence, additional submission of a preprint to EGUsphere is not possible. For such cases, we allow linking of a previous preprint to EGUsphere as an external preprint where it will undergo full peer review guided by an EGU editor. Please find more information on external preprints joining EGUsphere.

The action authors need to take is:

1. update their posted preprint on the external server with the latest version of your manuscript;
2. submit it as an "external preprint" to EGUsphere.

How do editors treat such manuscripts?

Please note that no corrections or revisions can be implemented at the access-review stage since the external preprint will not be re-posted on EGUsphere, but only opens a public discussion page with the abstract and the preprint PDF linked to the original source (external preprint server). Other than that, editors apply all criteria as for any other preprint submitted to AMT.

I have an EGUsphere question, who do I contact?

1. For non-technical questions related to the screening process of EGUsphere preprints, please contact the EGUsphere coordinator.
2. For technical questions related to user interfaces or automatic process emails, please contact the Copernicus Publications' editorial support team.

Where can authors find guidance on data and software deposition, availability, and citation?

Copernicus Publications is a signatory of the Commitment Statement in the Earth, Space, and Environmental Sciences.
