Supporting Information Guidelines

AGU requires that Supporting Information text, figures, all captions, and small tables be included in one PDF file.  Large data tables and other data files should be placed in appropriate data repositories following the guidelines for the Enabling FAIR Data Project (see FAQ’s here). These data sets should then be cited in the references. Supporting Information should not include discussion or key analysis.

For the main file, authors should download and make use of our Supporting Information template, available in Microsoft Word and LaTeX on our Checklists and Templates page.  Please upload the final PDF, not the original source version (Word or LaTeX), when submitting your template file. An example of a completed template is here.

How to Submit Supporting Information

Supporting information files should be submitted to AGU using the GEMS system at the time of manuscript submission. Please use the Supporting Information template for text, small tables, captions, and figures and convert this to a PDF. Please see the information above for more information on referencing data in AGU publications.

References in supporting information should also be cited in the main text and included in the reference list of the main paper so that they will be discovered, linked, and indexed. A separate list in the supporting information is not necessary.  Reference text does not count toward length limits.

If you are unable to upload your files to GEMS, email your journal editorial office for advice and/or FTP instructions.

Please note that all supporting information will be peer reviewed with your manuscript. Please remember that all publishing policies, including plagiarism and dual and prior publication, apply to supporting information.

What is Considered Supporting Information?

The purpose of the supporting information is to enable authors to provide and archive supporting information such as data tables, method information, figures, video, or computer software, in digital formats so that other scientists can use it.

The key criteria are that the supporting information:

  • supplement the main scientific conclusions of the paper but are not essential to the conclusions (with the exception of including data so the experiment can be reproducible);
  • does not include discussion or key analysis;
  • are likely to be usable or used by other scientists working in the field;
  • are described with sufficient precision that other scientists can understand them, and
  • are not .exe files.

What kinds of files are allowed?

AGU journals accept supporting information in most file formats, but more common programs (Microsoft Office, LaTeX, and figures in .eps or Illustrator, PDFs) are encouraged because they are less likely to limit other scientists’ access to data.

Text, graphics, figures, tables, spreadsheets, animations/movies, and sound files are all accepted. Use of the standard zip compression is permitted for software, databases, or computer code. Contact journal staff to discuss formats queries and concerns.

Supporting Information Naming Protocol

Authors are encouraged to follow this guide to name supporting files and to give the files the proper object title assignment in GEMS. The file names that the author uses at submission will appear online with the published article. Authors are encouraged to name files in a way that identify the supporting information with the paper. AGU encourages authors to name files with either the GEMS number (if available) or author names. The file should also include a naming convention in which xx is the number (e.g., 01, 02). For example, your file might be 2014JB011161-ds01.doc if you have an assigned GEMS number, or it might be authorname-ds01.doc if you do not have a paper number assigned.
