 ==History==
-Launched in 2014, the Accelerated Climate Model for Energy was initially aimed at addressing DOE's strategic objectives in climate and energy research. Over time, ACME evolved into the **Energy Exascale Earth System Model (E3SM)**, reflecting its growth and the shift towards using exascale computing resources. Key historical achievements included the development of high-resolution models for different climate components, which were instrumental in studying the impacts of climate change on energy systems. The transition to E3SM marked an expansion in scope, focusing on utilizing emerging high-performance computing capabilities to enhance model resolution and accuracy.
+E3SM was established in 2018 as an evolution from the Accelerated Climate Model for Energy (ACME), aiming to leverage DOE's investment in exascale computing. Since its inception, E3SM has focused on developing models that can run on DOE's latest supercomputers, significantly enhancing the resolution and complexity of climate simulations. Key milestones include the release of various model versions, each improving upon the previous in terms of resolution, process representation, and computational efficiency.
 ==Funding==
-Specific initial funding details were not publicly detailed, but ACME, before transitioning to E3SM, was funded through the DOE's Office of Science budget. Funding supported research, model development, and application across various labs and academic partners, with an emphasis on leveraging DOE's leadership computing facilities.
+In 2022, the U.S. Department of Energy (DOE) announced $70 million in funding for seven projects aimed at improving the E3SM. This funding was intended to accelerate development, enhance climate prediction, and support collaborations between climate scientists, computer scientists, and applied mathematicians.<ref>{{cite web |url=https://www.energy.gov/articles/doe-announces-70-million-improve-supercomputer-model-earths-climate-system |title=DOE Announces $70 Million to Improve Supercomputer Model of Earth's Climate System |accessdate=January 30, 2025}}</ref> Additionally, for fiscal year 2021, the DOE allocated $7.7 million for 11 studies focused on improving understanding of Earth system predictability through the E3SM. These projects were selected via competitive peer review under the DOE's Earth and Environmental Systems Modeling Program, sponsored by the Office of Biological and Environmental Research.<ref>{{cite web |url=https://climatemodeling.science.energy.gov |title=DOE Announces $7.7 Million for Earth & Environmental Systems Modeling |accessdate=January 30, 2025}}</ref>
 ==Implementation==
-The implementation of ACME involved:
+The implementation of E3SM includes:
-* Development of sophisticated Earth system models capable of high-resolution simulations.
+* Development of model components for atmosphere, ocean, land, ice, and biogeochemistry at unprecedented scales.
-* Utilization of DOE's high-performance computing resources for model runs.
+* Utilization of DOE's supercomputing facilities, notably the Summit and Frontier systems, for model execution.
-* Collaboration with scientists from multiple disciplines to refine models and interpret results.
+* Continuous model validation, refinement, and community engagement to ensure scientific robustness.
-The program ended as it transitioned into the broader E3SM initiative.
+The program is designed to be ongoing, adapting to new scientific discoveries and technological advancements in computing.
