Journal of Geophysical Research

Journal of Geophysical Research is a journal of the American Geophysical Union. It is often called by its initials, JGR. AGU states that JGR "publishes original scientific research on the physical, chemical, and biological processes that contribute to the understanding of the Earth, Sun, and solar system and all of their environments and components".

The AGU provides subscribers access to electronic versions of nearly all papers published in the JGR from 1994 to the present. In addition, since 1994, the AGU has provided online e-supplements to JGR articles, allowing data sets to be disseminated and archived along with electronic versions of the published articles.
