Text Requirements and Guidelines

AGU uses an entirely electronic process for submission, review, and publication.

 To make the preparation of your paper as efficient and economical as possible, we ask that you follow AGU’s  Grammar and Style Guide.

For submission we prefer to receive your manuscript in one of the following formats: Microsoft Word, LaTeX, or PDF. Figures and tables should be submitted as part of the main file.

If you are submitting separate files for images or supporting information,  please see our list of Acceptable File Formats for guidance.

Manuscript Submission Types

The AGU Editorial Style Guide for Authors provides a list of the most frequent changes made in editing. The complete AGU Grammar and Style Guide is available for download.

MS Word LaTeX
Format  .docx is preferred, but .doc is acceptable AGU Template and style files. See
LaTeX guidelines for templates and macros.
Font/type 12-pt Times New Roman
Language U.S. English
Paragraphs Indent or space between them
Footnotes Only use in tables and for affiliations. Incorporate potential footnotes intomain text, if needed.
Units of measure and chemical elements Do not use italic font for units of measure or chemical elements.
Math, both inline and full equations Use a program, such as MathType, that will produce editable equations.  Avoid special style macros

Instructions for Word Users

Word 2007 and 2010 files (.docx) are accepted, as are papers written in earlier versions of Word.

Where possible, create equations using MathType or another equation builder rather than the native equation editor in Word.

LaTeX Guidelines for Templates and Macros

For LaTeX, use the AGU template. Please DO NOT introduce into your files any extraneous formatting, new commands, macros, or shortcuts, as they are not compatible with the publishing process. Submitting files with these macros will require AGU to manually key information, which can introduce errors and prolong the time it takes to publish your work.

Because of this, regrettably, submitted papers with extensive extraneous formatting, macros, or shortcuts (including \def,\newcommands, \renewcommands, and especially those commands with #) will be sent back to the author for correction.

It is acceptable to use the following:

\ref and \label for figures, tables, and equations and \cite commands for reference citations.

The following AGU LaTeX manuscript preparation files are included: the AGU template, AGU style file, AGU class file, BibTeX files, and PDF and tex versions of AGU’s LaTeX instruction manual for authors.

  • AGU’s template, agutmpl.tex, is simple to use. Insert the letter code for the appropriate journal at the \documentclass level. Please do not use original templates.
  • AGU’s LaTeX style file, agutex.cls, has been designed to provide authors with advanced formatting capabilities in a single user-friendly style file. It is not necessary to use different style files for different journals.
  • Additional information and instructions are provided for special characters and formatting. Also see the LaTeX Formatting Toolkit.

Special BibTeX Instructions

  1. Run LaTeX on your LaTeX file.
  2. Run BibTeX on your LaTeX file.
  3. Open the newly created .bbl file containing the reference list and copy all of the contents into your LaTeX file after the acknowledgments section.
  4. Comment out the old \bibliographystyle and \bibliography commands.
  5. Run LaTeX on your new file before submitting.

Failure to follow these instructions will require information to be keyed manually, which can introduce errors and prolong the time it takes to publish your work.

When you submit your LaTeX document:

  • Submit in draft mode. Draft mode produces a double-spaced copy with a time and date of production stamp at the bottom. Figures and tables are positioned at the end of the file in this mode.
  • Use line numbering.
  • Comment out any graphics (e.g., \includegraphics, \figbox).
  • Submit figures separately. See Acceptable File Formats for what file types can be used.
  • For displayed equations, make sure that they break before the margins.
  • Insert \end{article}command after \end{thebibliography} so that captions and tables are included in the output.
  • To see what your article looks like in a single column format, which reflects the formatting of the AGU PDF, you must view your article in draft mode.

Manuscript Elements

Authors are asked to provide manuscripts and artwork as electronic files. For more information, see Acceptable File Formats.

The manuscript should be arranged in the following order:

  1. Title page including authors’ names, affiliations, and mailing address for corresponding author (including postal code)”
  2. Key Points
  3. Abstract
  4. Index Terms and Keywords
  5. Text (including appendices)
  6. Acknowledgments
  7. References
  8. Tables
  9. Figures
  10. Copyrighted material permission
  11. Supporting information/nonprint material (e.g., data sets, long tables, appendices, graphs).

1. Title/Authors

Title. A title should be specific, informative, and brief. Write it out without abbreviations. Use abbreviations in the title only if the abbreviation will be defined in the abstract.

Authors. Authors are individuals who have significantly contributed to the research and preparation of the article; all coauthors share responsibility for submitted articles. List each author name separately; a group cannot be listed as an author. Groups and other contributors who do not meet the authorship criteria should be appropriately acknowledged in the acknowledgments section. It is critical to have full and complete information, including affiliations for all authors and the postal address for the corresponding author, to facilitate indexing and full citations. For example:

Christopher R. Schwalm and Christopher A. Williams, Graduate School of Geography, Clark University, Worcester, Massachusetts, USA.

Kevin Schaefer, National Snow and Ice Data Center, University of Colorado Boulder, Boulder, Colorado, USA.

Corresponding author: C. R. Schwalm, Graduate School of Geography, Clark University, Worcester, MA 01610, USA. (cschwalm@clark.edu)

2. Key Points

Key Points convey the main points of the article as well as potentially stating conclusions. Up to three key point statements are allowed per article, and each must be 80 characters or less. with no punctuation. All characters in key points must be from the main ASCII table, not the extended ASCII table. At least one key point is required per article. For example,

Key points

  • Aerosol-cirrus interactions are simulated in a global climate model
  • Mineral dust and black carbon aerosol can affect cirrus globally
  • Cirrus ice types generated by different aerosol types are characterized

3. Abstract

The purpose of the abstract is twofold: (1) state the nature of the investigation and (2) summarize the important conclusions of this investigation. The abstract should be suitable for separate publication in an abstract journal and be adequate for indexing. Make sure to check for the following:

  • It is set as a single paragraph.
  • It is limited to 250 words for all journals except GRL where the limit is 150 words.
  • It does not include table or figure mentions.
  • If it has reference citations that are part of the sentence, they should be in roman type and have parentheses around the year; parenthetical reference citations will be deleted.
  • All abbreviations used in the abstract are defined.

4. Index Terms and Keywords

Index terms are a key part of AGU’s strategy for electronic distribution of journal articles.

Up to five index terms are allowed and should be provided at the time of submission. Use the AGU Index Set. Do not use terms ending in “00.”

Authors may also provide up to six keywords. These are free-form terms that can be used to facilitate online searches. Keywords should not be article types (regular, correction, brief, etc.).

5. Text

Text should be fully edited when submitted to the GEMS system. Accepted papers are not rough drafts. The following categories will help you format different parts of the paper.

Headings. Except for very short manuscripts (such as comments and replies), the text should be divided into sections, each with its own heading.

Sections are numbered with Arabic numerals (1, 2, 3, etc.). A maximum of four levels of heads may be used, with subsections numbered 1.1., 1.2.; 1.1.1., 1.2.1; 1.1.1.1., and so on. Headings should be sentence fragments and do not begin with a lowercase letter or number. They should not include parenthetical reference citations or table and figure callouts.

Footnotes. Incorporate footnoted information into text; footnotes are used only for affiliations, tables, and auxiliary material.

Reference citations. Use name-date format, not numbered references, and enclose citations in brackets with authors in italics.

  • [Smith et al., 2009] or
  • Smith et al. [2009]

Mathematics. If your article contains math, pay particular attention to breaks in the displayed equations.

AGU encourages authors to use MathType or another equation builder compatible with MathML for ease of editing and production.

  • Use italic for variables, bold for vectors and matrices, script for transforms, and sans serif for tensors.

math

  • Use superscripts and subscripts in superior or inferior position; do not use raised and lowered fonts.

math

  • Extend fraction bars under the entire length of the numerator.
  • Use the “degree” symbol instead of superscript lowercase “o.”

math

  • Use “exp” rather than “e” if the argument of an exponential function is complicated or lengthy.

math

  • Avoid awkward fractional composition by using negative powers.

math

  • Use shilling fractions (l/r) in text.

math

  • Use the following to avoid ambiguity

° In math: parentheses, brackets, and braces, in that order { [ ( ) ] }.

math

math
° In text, use only parentheses, e.g., (dogs (or cats) appear).

Number displayed equations consecutively within the article, not within the section. Place the equation number (in parentheses) to the right of the equation. Reaction numbers should be set to the left of the equation and preceded by “R.”

Equations in each appendix must be numbered separately, with the number preceded by the appendix letter (e.g., in Appendix A, the first equation would be (A1)).

Add one extra line space above and below all displayed equations.

math

Notation. The notation is a list of parameters and their definitions that are used in the text. They should be set up as shown in the following sample. Including a notation section is not mandatory, but all parameters should be defined in the text. A notation section is preferred in a manuscript with heavy use of mathematics.

c  rate of soil accumulation, m/yr.

d   median grain size of water-deposited material, μm.

D   distance of the locus of points, m.

h  elevation of the rock stream channel at a particular time ti, m.

6. Acknowledgments

Acknowledgments are an important part of the paper. Information on data availability must be listed here. It is also the appropriate place for collegial thanks and the listing of financial assistance and grant information. Acknowledgments are not meant to recognize personal or manuscript production support.

The first part of acknowledgments should include a listing of where to find the data that was used for the results of the paper. This includes data used to generate figures, graphs, plots, tables, and other media; protocols or methods; code; derived data products. The data can be made available as supporting information, in a data repository, can be made available upon request from the author or in other saved areas. Please see a more thorough description in AGU’s Data Policy and how the policy affects authors, reviewers, Editors and Associate Editors.

Funding information, if applicable, should be listed second. Please include the funding body and contribution number.

7. References

All sources cited in text, tables, and figures must appear in the reference list, and all entries in the reference list must be cited in text. References that are only cited in auxiliary material should not be included in the reference list of the paper but should be included in a separate reference list in the readme file for the auxiliary material. This section explains and gives examples for different elements of references:

  • text citations
  • reference list
  • DOI
  • reference examples for different media.

Text citations. References should be cited in one of two ways in text using author name(s) and the date of publication:

“in earlier studies [Johnson, 2009]” or “…as given by Johnson and Smith [2008].”

Note that author names are italicized and that a comma follows the author name(s) if the reference is enclosed in brackets.

For references by three or more authors, use et al. after the first author: [Zhang et al., 2005]

  • If a parenthetical citation includes two or more papers, separate the citations with a semicolon: [Forbes et al., 1999; Hausler and Wu, 2001].
  • If two or more citations by the same author(s) are listed consecutively, they should be combined: [Jones, 1999, 2001; Jones and Tuller, 2003, 2004; Jones et al., 2006, 2008].
  • To distinguish two or more papers by the same author(s) published in the same year, add a, b, c, etc., after the year: [Park, 1995a,1995b; Park et al., 2001a, 2001b, 2001c]; the corresponding letter should also appear with the date in the reference list.

Authors may be treated either as a person or as a work (i.e., both “in Taylor [1984]” and “in the work by Taylor [1984]” are acceptable).

There are a limited number of words and phrases that can be used within brackets beyond the citation itself. Words that can precede the reference within brackets include the following: see, e.g., cf., from, after, i.e.

These words or phrases can be used after the reference within brackets: and references therein, pp., equation, chapter, paragraph (for AGU journals published after 2002), Table, Figure, ff., hereinafter (plus abbreviation), this study.

Reference list. Reference entries should be ordered alphabetically by the last name of the first author.

AGU follows a strict letter-by-letter alphabetization, e.g., Lefer before Le Pichon and Sanders before St. Amant.

  • Only the first author’s initials and last name are given in reverse order.
  • A publication date must be given for each reference. For a Papers in Press article, use the current year as the date.

List references by the same first author in the following order:

1. first author alone, chronologically;

Smith, R. (2000a), ….

Smith, R. (2000b), ….

Smith, R. (2003), ….

2. with one coauthor, alphabetically by coauthor and then chronologically;

Smith, R., and L. A. Frank (1998), ….

Smith, R., and F. A. Allen (2001), ….

Smith, R., and L. A. Frank (2001), ….

3. with two or more coauthors, chronologically only.

Smith, R., and D. H. Roberts (2005)

Smith, R., D. H. Roberts, and J. Jones (1998), ….

Smith, R., F. A. Allen, and T. L. Baker (1999), ….

Smith, T. (1998), ….

Alphabetize different first authors having the same last name according to the initials of their first names. Note the use of lowercase letters to allow differentiation of text citations of work published in the same year.

DOI. The Digital Object Identifier (DOI) is a system for identifying and exchanging intellectual property in the digital environment. The DOI is a required part of the citation for AGU journal articles. This practice began at AGU in 2002. When they are known, DOIs should be included for non-AGU publications.

Here is an example of a DOI from a Journal of Geophysical Research-Atmospheres article (prior to 2013): doi:10.1029/2004JD005720

 8. Tables

Title. Every table must have a unique title. Titles should be clear and concise, and they should not be complete sentences. Explanatory information and definitions should be included in a footnote to the title.

Column heads. All columns (except the first one) must have headings. Column headings must be arranged so that their relation to the data is clear and they refer to column below.

Format

  • Each entry in a table should appear in a new cell.
  • Avoid tables created with the tab key and embedded objects. There can be no color in tables. Tables with pictures, color, or embedded objects must be submitted as figures. Use footnotes or bold and italics instead of color in a table.
  • Tables must be editable and must not be embedded as pictures.
  • Footnotes should be indicated by superscript, lowercase letters.

Numbering. Cite each table in numerical orderin text. Tables in the main body of the text should be numbered consecutively, not by section.

Appendix tables should be numbered separately from the body and should begin with the letter of the appendix (e.g., Table A1 for the first table in Appendix A).

Each table must be cited in text.

9. Figures

Refer to the Graphics Tab for accepted formats for submission, publication, and the archive.

For initial submission, each figure should also have a caption with the figure.

For revision submission, each figure must be uploaded separately without a caption, and for some journals a .pdf of all figures with their corresponding captions should also be included.

Format

• Indicate latitude and longitude on maps.

• Use lowercase letters to label parts of the figure; do not use Arabic or roman numerals.

• When possible, include the figure label in the top left corner of each plot.

• Do not include any information that could easily be included in the caption.

Captions. Provide list of captions in manuscript; do not include captions on the figures.

Numbering. Cite each figure in numerical order in text. figures in the main body of the text should be numbered consecutively, not by section.

Appendix figures should be numbered separately from the body and should begin with the letter of the appendix (e.g., figure A1 for the first figure in Appendix A).

Foldouts, pocket maps, etc., can be accommodated, but the costs for publishing these special features must be borne by the author. For additional information, contact the appropriate journal team.up-arrow

10. Copyrighted Material

Authors who use material (e.g., graphics, tables) from another author or copyright holder must obtain written permission to do so. This includes any figures redrawn but basically unaltered or with only slight modifications. Permission is not needed for material that originated in AGU journals or is in the public domain.

Permission must allow for the distribution of the material in any and all media in current and future formats.

Obtaining permission can be a lengthy process, so please make sure that you have the necessary permissions before you submit your manuscript to AGU.

Written permission(s) should accompany the revised manuscript when submitted. Articles will not be published until permissions are received at AGU.up-arrow

11. Supporting Material

 See Auxiliary Material Guidelines for more information.

Please note that all auxiliary material must be reviewed with your manuscript.

In general, the purpose of the auxiliary material or electronic data supplements is to enable authors to provide and archive auxiliary nonprint information such as data tables, figures, video, or computer software, in digital formats so that other scientists can use it.

The key criteria are that the data:

• are central to the main scientific conclusions of the paper;

• are likely to be usable by other scientists working in the field;

• are described with sufficient precision that other scientists can understand them;

• have a relatively small volume (up to 50 megabytes); and

• can be put into one of the required digital formats.

A given article’s auxiliary material consists of a small number <50mb of files, where each file contains either a text document, a table (data organized as rows and columns), a figure, or a video/multimedia file. The names and formats of these files follow simple standards designed to allow the publisher to archive the data, and scientists to read the data, for the indefinite future. The author transfers the files to AGU during the manuscript submission process using GEMS, or by anonymous FTP.

Movies, animations, downloadable data tables, calculation worksheets, and three-dimensional models are known as Dynamic Content. They allow authors to demonstrate, rather than simply explain, scientific findings. Files must therefore be in acceptable formats to guarantee long-term accessibility.

To learn more about the options, contact the appropriate journal team.up-arrow
