Frameworks: Large Scale Atmospheric Research Using an Integrated WRF Modeling, Visualization, and Verification Container Framework (I-WRF)

康奈尔大学和国家大气研究中心I-WRF项目正在为天气研究和预报（WRF）模型开发和部署一个集成的多容器框架，以实现具有验证和可视化功能的多节点容器化模拟。I-WRF降低了希望在多个平台上并行使用WRF的多学科研究人员的门槛，从桌面到云和超级计算机。通过使这套应用程序更容易和更有效地使用，I-WRF使更广泛的研究人员（大气科学家，土木工程师，农业科学家等）可以使用大气建模。他们不再必须自己建立和维护一套复杂的软件应用程序。多节点容器化框架的可移植性、可追溯性和易于部署性支持了对联合国气候变化会议所发出的未来可能气候状态进行更多和更好模拟的迫切需求，并建立了NSF工程研究愿景联盟，以发挥工程在应对气候变化中的作用。I-WRF应用容器包含主要由NCAR开发的软件工具。其中包括WRF模型和模型评估工具（METplus），以及为交互式调查而增强的可视化和分析工具。I-WRF容器经过优化，可在多个平台上运行，并支持对具有高水平空间离散化的大型域进行并行分析。它们将在一个容器存储库中免费提供，并可使用通用工具进行编译。制造商可以使用I-WRF容器组件来构建和修改自己的容器，从而节省时间，提高整体容器的可用性，并在科学界内部和之间进行共享。为了证明容器的有效性，将对一系列用例进行缩放研究。其中包括审查可再生能源发电在不断变化的气候中的演变，土地使用和气候变化对恶劣天气事件的影响，以及空气质量与人类发病率和死亡率之间的关系。三名博士后将参与用例研究。在台式机上运行I-WRF多节点模拟的能力将克服目前在NCAR和大学课程中培训学生使用WRF的障碍。该项目得到了计算机信息科学工程局和地球科学局高级网络基础设施办公室的支持&&。该奖项反映了NSF的法定使命，并通过使用基金会的智力价值进行评估而被认为值得支持和更广泛的影响审查标准。

The Cornell University and National Center for Atmospheric Research I-WRF Project is developing and deploying an integrated multi-container framework for the Weather Research and Forecasting (WRF) model to enable multi-node containerized simulations complete with verification and visualization capabilities. I-WRF lowers the bar for multidisciplinary researchers who wish to use WRF in parallel on multiple platforms, ranging from desktops to clouds and supercomputers. By enabling easier and more effective use of this set of applications, I-WRF makes atmospheric modeling accessible to a broader range of researchers (atmospheric scientists, civil engineers, agricultural scientists, etc.) who no longer must set up and maintain a complex suite of software applications on their own. The portability, traceability, and ease of deploying the multi-node containerized framework supports the urgent need for more and better simulations of possible future climate states signaled by the UN Climate Change Conference and the establishment of the NSF Engineering Research Visioning Alliance on The Role of Engineering in Addressing Climate Change.I-WRF application containers incorporate software tools developed mainly at NCAR. These include the WRF model and Model Evaluation Tools (METplus), as well as visualization and analysis tools that are enhanced for interactive investigations. I-WRF containers are optimized to run on multiple platforms and to enable parallel analysis of large domains with a high level of spatial discretization. They will be freely available at a container repository and discoverable with common tools. Adopters can use the I-WRF container components to build and modify their own containers, thus saving time and increasing overall container availability and sharing within and between scientific communities. To prove container validity, scaling studies will be performed on a range of use cases. These include examining the evolution of renewable energy generation in a changing climate, the effect of land use and climate change on severe weather events, and the relation between air quality and human morbidity and mortality. Three postdocs will engage in the use case studies. The ability to run I-WRF multi-node simulations on desktops will overcome current obstacles in training students to use WRF at NCAR and in university course curricula.This project is supported by the Office of Advanced Cyberinfrastructure in the Directorate for Computer & Information Science & Engineering and the Directorate for Geosciences.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.
