SammanfattningThe American Geophysical Union organizes and disseminates scientific information in the fields of geophysics, which include atmospheric and ocean sciences; solid-Earth sciences; hydrologic sciences; and space sciences. The agujournal2019 LaTeX class provides formatting for all AGU journals in the correct APA style. This template allows for direct submission to Geophysical Research Letters. This template is based on the one from the official author guidelines. See the instructions on that page for complete information. AGU also provides some LaTeX tips for authors. Geophysical Research Letters publishes high-impact, innovative, and timely research on major scientific advances in all the major geoscience disciplines. Papers are communications-length articles and should have broad and immediate implications in their discipline or across the geosciences. GRL maintains the fastest turn-around of all high-impact publications in the geosciences and works closely with authors to ensure broad visibility of top papers.
