Scientist Likes New Project for U.S. Climate Model

16 months ago, climate change scientists expressed concern about a new climate model sponsored by the United States Department of Energy (DOE), fearing that it may draw away talent and funding, endangering existing model projects, because of federal and human-funded scientific projects Both are extremely lacking. Their biggest concern is that the Accelerated Energy Climate Model (ACME) project, which aims to predict the local effects of climate change and will operate on DOE's tens of billions of sub-supercomputers in the future, may dilute the Common Earth System Model (CESM) project. Resources.

The CESM was managed by the National Center for Atmospheric Research (NCAR) of Colorado and was gradually established by American scholars and DOE scientists according to scientific needs and partially funded by DOE. In addition, NASA and the National Oceanic and Atmospheric Administration, the Federal Space and Ocean Agency, have two other models, respectively. So, do you want to create the sixth US climate model project?

At present, the project has passed six months since its initial coding. DOE scientists established ACME using the coding of CESM. Currently, the two projects are in tandem, which has potential benefits for both projects. Although the CESM team is still uneasy, the NCAR climate model expert Jean-Francois Lamarque wrote in an e-mail: “The two projects should provide affirmation of the potential benefits of the expansion and simulation approach.” He added that both The "new collaboration" brought about by the marriage of the two projects has been proved to be "effective."

In early December 2014, the DOE released an updated public profile that clarified the purpose and method of the project and was publicly presented at the American Geophysical Society meeting in San Francisco, California. Scientists explained to Science how the marriage will shape the two projects involved. They said that it is conceivable that the CESM project is a Swiss army knife; it was established to merge hundreds of small-scale, all-aesthetic physics and similar projects, intended for regional modelers, practical climate scientists and even for other planets. Planetary scientists of the climate model provide services. In comparison, ACME is a dedicated kitchen knife that focuses on three objectives: simulating the water cycle, biogeochemistry, and the role of the Earth's cryosphere.

Maintaining a harmonious relationship between the two projects depends on whether the two models can continue to be compatible in the future. Some researchers warned that because they are designed according to different computer operations, the two are expected to separate in the future. ACME will operate on DOE supercomputers and may differ from the current Wyoming Supercomputing Center's maintenance of NCAR and CESM's supercomputing tools.
