Special issue guidelines

Atmospheric Chemistry and Physics (ACP) and its discussion forum Atmospheric Chemistry and Physics Discussions (ACPD) offer an efficient new way of publishing special issues for measurement campaigns, conferences, etc. The individual papers are peer-reviewed and published as soon as they are available in regular issues;  they are then labelled as part of the special issue and linked electronically.

The specific advantages are the following:

  • Publication date is not delayed by the latest paper, which is behind in the peer-review process: every individual contribution to the special issue is published as soon as it is available.
  • Efficient interactive discussion of the common theme takes places on the ACPD website.
  • Prepublication of discussion papers in ACPD allows efficient cross-referencing between the final revised papers in ACP.
  • All contributions are efficiently linked and coherently presented on dedicated special issue web pages (an appropriate logo is welcome as a *.jpg file) easily accessible from the ACP/ACPD online libraries.
  • Special issue coordinators can define the order of the published papers on the SI web page.
  • Either a non-peer-reviewed editorial preface or a peer-reviewed scientific paper can be used to introduce a special issue.
  • Print versions are available upon completed publication of all contributions. A minimum order of 20 copies is necessary, and the price will depend on the total number of pages in the special issue.  
    The price per printed copy is calculated as follows: number of pages × €0.09 + softcover and binding (€3.00) (hardcover price on request) + priority mail (individually calculated) = net price + VAT Please contact the Copernicus Publications Production Office for an official offer.

Inter-journal special issues

A special issue can comprise publications in any number of Copernicus’ open-access journals, and the special issue editors can be from the same or different journals. It may, however, be advantageous to have representation from editorial board members from more than one of the constituent special issue journals. One journal should be nominated as the notional lead for administrative purposes. The manuscript processing follows the standard special issue procedure of the journal in which the manuscript is submitted. Afterwards, all published papers are co-listed on a joint special issue web page (in addition to the regular chronological volume of each journal).

If you intend to propose an inter-journal special issue, please first send your proposal to the executive editors of the lead journal. If your proposal is accepted, please also contact the executive editors of the constituent journals to find out if they want to participate in the inter-journal special issue. Only after all journals have agreed, should all information (see below) on the inter-journal special issue be sent to the Copernicus Publications Editorial Support.

Special issue proposal

The following points should be considered:

  • The special issue and all manuscripts to be published in it must be within the journal scope and comply with the manuscript types and with the same quality standards as regular submissions to ACP. Please notice and consider in particular that ACP's scope is focused on studies with general implications for atmospheric science rather than investigations which are primarily of local or technical interest.
  • ACP special issues usually have a few dedicated special issue editors who are members of the ACP editorial board with experience in the subject area of the special issue. Please select appropriate co-editors from the editorial board of ACP and contact them directly to see if they are ready to act as co-editors for the planned special issue. The number of special issue editors should reflect the expected number of submissions (about one editor per six submissions per year). Normally, the special issue editors should not be closely involved in the work from which the special issue arises (please see the general obligations for editors). If appropriate – especially for large special issues – one or two closely involved scientists may become special issue editors but should help with the editor assignment process rather than handling submissions by themselves.
  • Special issue papers are published in the regular issues as well as in special issues as soon as the review process is completed.

Please send proposals for special issues to with the following information:

  • title of the special issue;
  • start date and end date of submission;
  • expected number of papers;
  • a statement of the purpose of the special issue, whether it arises out of a conference, and whether it will include only invited papers or is open for all submissions within its scope;
  • names of proposed special issue editors;
  • names of constituent journals if it is to be an inter-journal special issue, with the lead journal identified (see above).
