The overarching aim of MEZCAL is to make a step change in monitoring the spatiotemporal evolution of the Atlantic meridional overturning circulation (AMOC) from indirect observations. MEZCAL will achieve this aim by delivering the following objectives: O1) Design and implement a spatiotemporally complete AMOC framework from indirect observations using proven reconstruction techniques. O2) Extend AMOC records backwards in time using machine learning and adjoint methods. O3) Make recommendations for an AMOC monitoring framework and enhanced observations to ensure a sustainable future AMOC monitoring system. In addition to contributing important scientific advancements relevant to our changing climate, this project will support two early career scientists (Le Bras and Amrhein) as well as a postdoc. Le Bras is committed to communicating the results of this project to a broad audience through talks with students, the public, and media platforms. She will continue to participate in organizing efforts for the oceanographic LGBTQ+ community. With support from this project and NSF-supported project FOCUS (OCE-2123692), Piecuch will ensure that findings from MEZCAL and the sea-level implications are communicated to coastal stakeholders and practitioners. Amrhein is committed to developing community software and scientific resources through efforts with the Community Earth System Model and NCAR, including spearheading data assimilation and regional modeling efforts to communicate climate impacts across scales. He is also an active member of the paleoclimate modeling and data community, and will serve as a cross-disciplinary bridge for AMOC science. By extending observation-based AMOC records spatially and backwards in time, MEZCAL will enable significant scientific discovery. It will address whether the AMOC has declined in the last century, and what the meridional connectivity and structure of the AMOC is: both important questions to address to better understand our climate system. MEZCAL will provide recommendations for the AMOC observing system, which will benefit the wider oceanographic observing community, and the modeling work will provide insight into climate model biases.This is a project jointly funded by the National Science Foundation’s Directorate for Geosciences (NSF/GEO) and the National Environment Research Council (NERC) of the United Kingdom (UK) via the NSF/GEO-NERC Lead Agency Agreement. This Agreement allows a single joint US/UK proposal to be submitted and peer-reviewed by the Agency whose investigator has the largest proportion of the budget. Upon successful joint determination of an award recommendation, each Agency funds the proportion of the budget that supports scientists at institutions in their respective countries.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.

梅斯卡尔（Mezcal）的总体目的是在监视大西洋子午倾斜循环（AMOC）中从间接观察结果中进行逐步改变。 Mezcal将通过实现以下目标来实现这一目标：O1）使用经过验证的重建技术从间接观察中设计和实现空间完整的AMOC框架。 O2）使用机器学习和伴随方法在时间上向后扩展AMOC记录。 o3）为AMOC监视框架和增强的观察提出建议，以确保可持续的未来AMOC监视系统。除了贡献与我们不断变化的气候相关的重要科学进步外，该项目还将支持两位早期的职业科学家（Le Bras和Amrhein）以及博士后。 Le Bras致力于通过与学生，公众和媒体平台的谈判将该项目的结果传达给广泛的受众。她将继续为海洋学LGBTQ+社区组织工作。在该项目和NSF支持的项目Focus（OCE-2123692）的支持下，PIECUCH将确保将Mezcal和Sea Level的发现传达给沿海利益相关者和从业者。 Amrhein致力于通过与社区地球系统模型和NCAR的努力来开发社区软件和科学资源，包括率领数据同化和区域建模工作，以跨尺度传达气候影响。他还是古气候建模和数据界的活跃成员，并将作为AMOC科学的跨学科桥梁。通过在空间和及时向后扩展基于观察的AMOC记录，Mezcal将实现大量的科学发现。它将解决上个世纪的AMOC是否有所下降，以及AMOC的子午连通性和结构是什么：要解决我们的气候系统以解决我们的气候系统。 Mezcal将为AMOC观察系统提供建议，该系统将使广泛的海洋观测界受益，并且建模工作将为气候模型偏见提供洞察力。这是一个由国家科学基金会地球科学局（NSF/GEO）和英国国家环境研究委员会（NERC）共同资助的项目，该项目通过NSF/GEO-GEO-NERC领先机构协议。该协议允许该机构提交和同行评审的一项联合提案，其调查员的预算比例最大。在成功确定奖励建议后，每个机构都资助了支持其各自国家机构科学家的预算比例。该奖项反映了NSF的法定任务，并通过使用该基金会的知识分子优点和更广泛的影响来审查标准，被认为是通过评估来获得的支持。
