Paper Types

Research Articles present fully developed analysis, results, and discussion of on scientific topics within the scope of the journal. They are expected to present new theories and novel concepts along with their applications, and the results should be significant. Although there is no limitation of space, to encourage clarity, and conciseness of presentation excess length fees are charged for manuscripts longer than 25 publication units. These manuscripts are handled by the editorial staff of the journal and are typically sent to multiple reviewers.

Research Letters (in Geophysical Research Letters) are communications-length articles on major scientific advances in all major geoscience disciplines. Papers and should have broad and immediate implications in their discipline or across the geosciences.

Commentaries provide reflections or context around a recent article in an AGU or another journal, an emerging or controversial topic in a specific scientific field, a scientific topic with societal implications, or a recent meeting, session, or workshop. Although submitted to a specific journal the audience is the broad Earth and space science community. Recommended length is 1-3 published pages (up to 6 publishing units with a table or figure). For further details see Commentaries in AGU Journals: Guidelines for Authors.

Review Articles are invited or submitted papers that review and synthesize recent literature on a given topic. Recommended length is 10-15 published pages excluding references and supporting material (no more than 30 publishing units with approximately 6 figures or tables).

Comments elaborate, criticize, or correct papers previously published in AGU journals. Comments are limited to the equivalent of 2 published pages (about 5 publishing units).

Replies are written by the authors of the paper being commented on. Replies are limited to the equivalent of 2 published pages (about 5 publishing units).

Frontier Articles (in Geophysical Research Letters) are invited articles that present a review of recent cutting-edge advances in a leading scientific field at the forefront of one or several AGU disciplines, if possible including new results.

Technical Reports: Data papers describe important Earth and space science data sets and observations, including those that support innovative research and theoretical developments published elsewhere. The papers should provide an example of a relevant scientific application to demonstrate the usefulness of the data. The data set may refer to experimental studies, lab measurements, modeling output, or observations. These papers should not exceed 13 Publication units.

Technical Reports: Methods papers describe new analytical or experimental methods and other technical advances, including computer programs and instrumentation, that enable new science. These papers should not exceed 13 Publication Units and will typically include at least one illustrative example application.
