GEO OSE Track 2: Enhancing usability of the Parallel Ice Sheet Model (PISM) to accelerate innovative sea-level research

平行冰盖模型（PISM）允许研究人员回答有关地球冰川和冰盖的过去，现在和未来的问题。PISM是在开放环境下开发的，其代码可免费向公众开放。尽管如此，PISM并不容易为所有用户使用。此外，尖端研究还需要获得超级计算机的知识，这可能会给研究人员带来经济负担或导致时间限制，或两者兼而有之。该项目的目标是通过使PISM更容易安装和使用来加速创新的海平面研究，从而使研究人员有更多的时间专注于科学。该项目将有利于不断增长的PISM用户社区以及更广泛的海平面研究社区。PISM的拟议包装和易于使用的云版本PISM预计将吸引新的研究人员到该领域，并减少现有用户的科学时间，从而有更多的时间来开发新的创造性和创新性的海平面科学是可重复的。上述目标，使PISM更容易使用，从而促进冰川学和海平面上升的研究，将实现：1.通过社区首选渠道（例如Spack、Conda、Debian）打包和分发PISM版本; 2.为PISM开发一个云原生仿真平台，PISM-Cloud，可以在几分钟内设置，只需点击几下鼠标，并通过一个笔记本电脑界面进行访问，3.生成基于PISM-Cloud的工作示例“PISM-Cloud 7”，用户将能够参与下一个社区工作，以估计格陵兰岛未来的冰损失（“冰盖建模CMIP 7相互比较”，简称ISMIP 7）4.举办培训班; 5.为参与ISMIP 7的团体提供对云计算资源的选择性免费访问。项目研究人员将使用PISM-Cloud 7参与第七届冰盖建模相互比较项目（ISMIP 7）。此外，一个培训研讨会将帮助新的研究人员开始使用PISM-Cloud 7，并为ISMIP 7社区做出贡献。PISM-Cloud还将使教育工作者更容易将冰盖建模和海平面研究的实践经验纳入基于PISM-Cloud 7研讨会材料和文档的课程中。该奖项反映了NSF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而被认为值得支持。

The Parallel Ice Sheet Model (PISM) allows researchers to answer questions about the past, present, and future of the Earth's glaciers and ice sheets. PISM has been developed in the open, with its code freely accessible to the public. Despite this, PISM is not as easy to use for all users. In addition, cutting edge research also requires access to and knowledge of supercomputers, which can either create a financial burden on researchers or result in time constraints, or both. The goal of this project is to accelerate innovative sea-level research by making PISM easier to install and use, thus giving researchers more time to focus on science. This project will benefit the growing community of PISM users as well as the broader sea-level research community. The proposed packaging of PISM and the easy-to-use cloud version of PISM are expected to attract new researchers to the field and reduce the time to science for existing users, resulting in more time available to develop novel creative and innovative sea-level science that is reproducible.The above goal of making PISM easier to use, and therefore facilitating glaciology and sea level rise research, will be achieved by: 1. packaging and distributing PISM releases through community preferred channels (e.g. Spack, Conda, Debian), 2. developing a cloud-native simulation platform for PISM, PISM-Cloud that can be set up within a few minutes and with a few mouse clicks and accessed through a Jupyter notebook interface, 3. generating a working example “PISM-Cloud7” built upon PISM-Cloud with which users will be able to participate in the next community effort to estimate future ice loss from Greenland ("Ice Sheet Modeling Intercomparison for CMIP7", ISMIP7 for short) 4. hosting a training workshop, and 5. providing select free access to cloud-computing resources to groups participating in ISMIP7. Project researchers will use PISM-Cloud7 to participate in the 7th Ice Sheet Modeling Intercomparison Project (ISMIP7). In addition, a training workshop will help new researchers getting started with PISM-Cloud7 and to contribute to the ISMIP7 community effort. PISM-Cloud will also make it easier for educators to include hands-on experience in ice sheet modeling and sea-level research in their curricula based on PISM-Cloud7 workshop materials and documentation.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.
