The American Geophysical Union organises and disseminates scientific information in the fields of geophysics, which include atmospheric and ocean sciences; solid-Earth sciences; hydrologic sciences; and space sciences. The agutex LaTeX class provides formatting for Journal of Geophysical Research, Global Biochemical Cycles, Paleoceanography, Radio Science, Reviews of Geophysics, Tectonics, Water Resources Research, Geochemistry, Geophysics, Geosystems, Space Weather, Journal of Advances in Modeling Earth Systems (JAMES), and Earth's Future. This template is based on the one from the official author guidelines, downloaded May 2018. The example file has been modified to show how to use BibTeX to generate references in the official AGU style. The class provides a draft option to be used for submission to the AGU, in addition to the final output — see the comments in the main file for more information.
