Support for the World Climate Research Programme 2023 - 2025

世界气候研究计划(WCRP)的项目基于与更广泛的国际科学界、合作伙伴和赞助商，包括美国全球变化研究计划(USGCRP)成员的讨论结果。该项目追求与耦合气候系统相关的前沿科学问题，这些问题太大太复杂，无法由单一的国家、机构、机构或科学学科来解决。通过这个项目，WCRP将来自美国和世界各地的科学家聚集在他们职业生涯的所有阶段，以促进我们对气候系统组成部分和外部强迫之间的多尺度动态相互作用的理解，以及处理和研究人类在气候和社会中的作用。WCRP通过与未来地球等其他项目的伙伴关系，为政策的制定和注重业务的气候服务提供信息，并促进科学能力建设和教育。该项目将促进对地球气候系统的科学知识和理解，并提供支持气候风险管理和解决方案所需的气候信息。被细分为两个支柱的拟议活动与USGCRP的两个新支柱(1)促进科学和(2)促进国际协调相关并产生共鸣。WCRP将促进对地球系统潜在引爆点的了解，强调可能跨越门槛并导致引爆点的物质和社会系统之间的复杂相互作用。该项目将克服气候模型中长期存在的系统误差。将采取严格的方法收集和分析气候数据，以了解导致极端事件的潜在机制；以及跨越一系列复杂性、过程和空间分辨率的各种建模和模拟方法。该项目将开展与降水研究有关的新活动，包括WCRP计划的水十年。它将与美国的相关活动联系起来，并开展新的努力，特别是在南美洲和非洲，这些地区正在结成新的联盟，以支持开展区域全球降水实验活动。将开展关于水和水可获得性的端到端工作，还将具体处理水文循环变化对社会的影响。资金还将用于在美洲和非洲大陆建立区域工作，共同开发和共同提供这些地区的气候信息。这也将包括下一代气候科学家的能力发展和培训。这一奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

The project of the World Climate Research Programme (WCRP) is based on the outcomes of deliberations with the broader international scientific community, partners, and sponsors, including members of the United States Global Change Research Program (USGCRP). The project pursues frontier scientific questions related to the coupled climate system that are too large and too complex to be tackled by a single nation, agency, institution, or scientific discipline. Through this project, WCRP brings together scientists from the US and around the world, at all stages of their careers, to advance our understanding of the multi-scale dynamic interactions between components of the climate system and external forcing, as well as addressing and studying the role of humans on climate and society. WCRP informs the development of policies and operationally focused climate services, and promotes science capacity building and education, which is done through partnerships with other programs such as Future Earth. The project will advance the scientific knowledge and understanding of the Earth’s climate system, and to provide the climate information needed to support climate risk management and solutions. Proposed activities subdivided into two pillars are relevant for and resonate with two of USGCRP’s new pillars (1) Advancing Science and (2) Advancing International Coordination.WCRP will advance understanding of potential tipping points in the Earth system, emphasizing the complex interactions between physical and social systems that could cross thresholds and lead to tipping points. The project will overcome long standing systematic errors in climate models. A rigorous approach will be pursued for climate data collection and analyses to understand the underlying mechanisms leading to extreme events; as well as a diversity of modeling and simulation approaches that span a range of complexity, processes, and spatial resolutions. The project will develop new activities related to precipitation research, including WCRP’s planned Decade of Water. It will connect to the relevant US activities and spin up new efforts, especially over South America and Africa where new alliances are being formed to support the delivery of regional Global Precipitation Experiment activities. End-to-end work on water and water availability will evolve that will specifically also deal with the impact of changes of the hydrological cycle on societies. Funds will also be used to establish regional work in the Americas and on the African continent to co-develop and co-deliver climate information in those locations. This will also cover capacity development and training of the next generation of climate scientists.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.
