The following types of manuscripts can be considered for peer-reviewed publication in Atmospheric Chemistry and Physics (ACP): research articles, ACP Letters, review articles, technical notes, measurement reports, commentaries, and special issue overview articles as detailed below.
- Research articles report substantial new results and conclusions from scientific investigations of atmospheric properties, and processes within the scope of the journal. Research articles must include substantial advances and general implications for the scientific understanding of atmospheric chemistry and physics. Manuscripts that report substantial new measurement results, but where the implications for atmospheric chemistry and physics are less developed, may be considered for publication as measurement reports (see below).
- ACP Letters are research articles that report particularly important results and major advances in a concise and engaging style. Letters have fewer than 2,500 words in the main text, 200 words in the abstract, and an appropriate number of figures, or tables, and references. For more information, see the instructions for authors. Papers accepted for final publication as ACP Letters will also become "Highlight articles", which have high visibility in EGU. Manuscripts submitted for consideration as ACP Letters are subject to regular peer review with interactive public discussion, and the selection procedure is overseen by the ACP executive committee.
- Review articles summarize the status of knowledge and outline future directions of research within the scope of the journal. Before preparing and submitting a review article, please contact the executive editors with a draft outline or summary of the prospective article (less than two pages). Review articles can be superseded by an updated version in order to incorporate a significant amount of new information (similar to the "living reviews" concept). The new article should contain a direct reference to the preceding article, both in the abstract and introduction sections. Please contact the executive editors if you would like to update your review article. Depending on the subject and further characteristics, review articles are also eligible for inclusion in the Encyclopedia of Geosciences. If you are interested in this option, please see the author instructions and contact the editors of the encyclopedia.
- Measurement reports present substantial new results from measurements of atmospheric properties and processes from field and laboratory experiments. Analysis of the measurements may include model results and conclusions of more limited scope than in research articles. The title must clearly reflect the manuscript type and start with "Measurement report:". The data presented in measurement reports must be openly accessible in accordance with the EGU data policy. For manuscripts focused on pure data reporting, we recommend submission to the interactive open-access journal Earth System Science Data (ESSD).
- Opinions are concise, authoritative articles written by experts that include agenda-setting and/or provocative viewpoints on topical issues within the scope of the journal. Topics of relevance include perspectives on recent major research developments, policy or societal issues, as well as perspectives on the historical or future direction of the author's area of expertise. Opinions should be insightful and informative for a wide readership and written in an engaging style. The open review and discussion is intended to stimulate scientific debate and overseen by the ACP executive committee. Opinion articles are generally invited, but authors with ideas for an opinion paper are encouraged to contact an executive editor. The title must clearly reflect the manuscript type and start with "Opinion:".
- Technical notes report new developments, significant advances, or novel aspects of experimental and theoretical methods and techniques that are relevant for scientific investigations within the scope of the journal (including assessments/developments of new/improved emission inventories). The title must clearly reflect the manuscript type and start with "Technical note:". For manuscripts focused on the development, intercomparison, and validation of measurement instruments and data processing techniques, we recommend submission to the EGU interactive open-access journal Atmospheric Measurement Techniques (AMT). For manuscripts focused on the development and description of numerical models and model components, we recommend submission to the EGU interactive open-access journal Geoscientific Model Development (GMD).
- Commentaries continue the discussion of published papers beyond the limits of immediate interactive discussion. They will usually refer to papers published in ACP, but may refer to papers published in other journals if satisfactory justification is given. They undergo the same process of peer review, publication and interactive discussion as research articles and other manuscripts, and they are equivalent to the peer-reviewed commentaries in traditional scientific journals. The manuscript title should start with "Comment on" or "Reply to".
- Overview articles synthesize and summarize the findings and conclusions of the papers published in a special issue. The manuscript title must clearly reflect the relation to the special issue and start with "Overview:".
- Corrigenda correct errors in preceding papers, whereby the authors should indicate the reasons for correction and explain the changes. The manuscript title reads as follows: Corrigendum to "TITLE" published in JOURNAL, VOLUME, PAGES, YEAR. The publication of corrigenda is overseen by the executive editors, who may also involve the handling editor and reviewers of the original paper. Please note that corrigenda are only possible for final revised journal papers and not for the corresponding discussion papers.
Upon recommendation by the handling editor and approval by the ACP executive committee, research articles and review articles can be selected as "highlight articles" to be promoted on the ACP and EGU websites. These highlight articles are considered to be of particular interest to the broad geoscience community or to the broader public and media (cf. EGU newsworthy research guide). Articles that are accepted for final publication as ACP Letters are automatically treated as highlight articles.
