Collaborative Research: Frameworks: A community platform for accelerating observationally-constrained regional oceanographic modeling

海洋是气候系统和全球碳收支的重要组成部分。海洋还支持粮食安全、全球贸易和能源生产。为了理解和管理这些用途及其影响，需要将海洋状态的高保真模型的观测和结果结合起来。目前，这种能力只提供给一个小的专家社区。该项目增强了社区地球系统模型（CESM）的能力，使更大、更多学科的用户社区能够解决有关地球海洋的重要问题。新的观测工作，如海洋生命体征网络（OVSN），可以利用该项目产生的工具来设计更好的观测系统，最大限度地从观测中获得信息，并最终提供满足利益相关者需求所需的决策支持。该项目旨在极大地扩大社区对适合目的的海洋模拟和状态估计的访问，从而使更多样化的社区能够应用。基础设施将明确支持端到端工作流上下文中的健壮可用性。该项目将产生清晰的文件，包括传播工具的明确机制，并以认真努力教育和培训多样化的用户社区为特色，包括来自传统研究界以外的用户社区。实习将支持历史上代表性不足的群体的参与，一系列讲习班将在传统上服务不足的社区建立能力。该项目将提供软件基础设施，促进CESM中模块化海洋模型版本6 （MOM6）的快速配置、部署和分析。一个共同的框架将支持高分辨率的区域域，这些区域域是由数据集横向强迫的，或者嵌入到一个全球模型中，用于全耦合或仅限海洋的模拟。这些配置将支持使用海洋生物地球化学库（MARBL）进行灵活的海洋生物地球化学模拟，以及使用数据同化研究试验台（DART）进行数据同化应用。开发将受到一个新用例的技术要求的考验和推动：设计和支持一个密集的、面向社区的观测阵列OVSN的解释，该阵列旨在显著提高测量和理解海洋物理、化学和生物动力学的功能和未来演变的能力，重点是碳循环。这个项目将减少建模工作流所有阶段中的技术瓶颈。最终目标是加速区域海洋状态估计的进展，并促进不同社区的应用。该奖项由美国国家科学基金会高级网络基础设施办公室颁发，由美国国家科学基金会地球科学理事会的研究、创新、协同作用和教育司（RISE）和海洋科学司（OCE）以及国家气候发现云（NDC）开发基金共同支持。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

Oceans are a critical element of the climate system and global carbon budget. Oceans also support food security, global trade, and energy production. A fusion of observations and results from high-fidelity models of the ocean's state are needed to understand and manage these uses and their impacts. Presently, this capability is available to only a small expert community. This project augments the capabilities of the Community Earth System Model (CESM) to enable a larger and more multidisciplinary community of users to address important questions about Earth's oceans. New observational efforts, such as the Ocean Vital Signs Network (OVSN), can leverage the tools generated by this project to design better observing systems, maximize information gained from observations, and ultimately provide the decision support needed to meet stakeholder needs. The project aims to greatly expand community access to fit-for-purpose ocean simulations and state estimates, thereby enabling applications by a more diverse community. The infrastructure will explicitly support robust usability in the context of end-to-end workflows. The project will produce clear documentation, include explicit mechanisms for disseminating the tools, and feature conscientious efforts to educate and train a diverse community of users, including from beyond the traditional research community. Internships will support participation of historically under-represented groups and a series of workshops will build capacity in traditionally underserved communities. This project will deliver software infrastructure facilitating rapid configuration, deployment, and analysis of the Modular Ocean Model version 6 (MOM6) within the CESM. A common framework will support high-resolution regional domains forced laterally by datasets or embedded online within a global model for fully-coupled or ocean-only simulations. These configurations will support flexible ocean biogeochemistry simulations using the Marine Biogeochemistry Library (MARBL) and the application of data assimilation using the Data Assimilation Research Testbed (DART). Development will be tested and motivated by the technical requirements of a novel use case: designing and supporting interpretation of an intensive, community-oriented observational array, the OVSN, which seeks to dramatically improve capacity to measure and understand the function and future evolution of the ocean's physical, chemical and biological dynamics, with a focus on carbon cycling. This project will reduce technical bottlenecks within all stages of modeling workflows. The ultimate objective is to accelerate advances in regional ocean state estimation and facilitate applications by a diverse community.This award by the NSF Office of Advanced Cyberinfrastructure is jointly supported by the Division of Research, Innovation, Synergies, and Education (RISE) and the Division of Ocean Sciences (OCE) within the NSF Directorate for Geosciences, and funds for development of a National Discovery Cloud (NDC) for Climate.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
