The American Geophysical Union is pleased to announce that effective immediately, it is the new publisher of the Journal of Advances in Modeling Earth Systems (JAMES). JAMES is a peer-reviewed, open-access, all-electronic journal that advances the science of Earth systems modeling by offering high-quality scientific research articles. JAMES was founded by the Center for Multiscale Modeling of Atmospheric Processes, a U.S. National Science Foundation—sponsored Science and Technology Center, and the journal began publishing peer-reviewed articles in the summer of 2009. Until now, the journal has been published by the Institute of Global Environment and Society.
