Reviewer resources



AGU’s journals rely on reviewers who are experts in their field to help maintain the highest standards and timeliness of our publications, and to maximize the impact of authors’ research. The peer review process is the cornerstone of scientific inquiry and is vital to ensuring the credibility of research and advancing human knowledge. All reviewers are expected to uphold our ethical guidelines and to disclose any conflicts of interest to the editors. Reviewers are expected to keep manuscripts confidential.

Guidelines for reviewers

It is important to meet the review deadline but if you are unable, contact the journal staff immediately. Extensions are granted at the editor’s discretion. Please submit your review online using the link provided in the emails.

Final decisions on acceptance or rejection are made by the editors. You will be informed promptly of the final decision.
