The Canadian Optimized High-Resolution Representation of the National Terrestrial Carbon Cycle (COHERENT-C) project is a partnership between Canada's academic carbon science community and Environment and Climate Change Canada (ECCC). The main objective of this project is to rapidly advance Canada's skill at representing and predicting Canada's terrestrial carbon cycle as climate, disturbances, and atmospheric greenhouse gas concentrations evolve. The results of this project will include 1) annual summaries for policy makers on the past and future state of Canada's carbon sinks and sources, and 2) scientific publications and presentations detailing an improved understanding of the vulnerability of carbon cycle processes in Canadian forests, wetlands, and the North. By addressing these knowledge gaps, we will support Canada's ability to harness nature-based solutions to combat climate change and provide climate forecasts needed for climate change adaptation throughout the country. To achieve these results, COHERENT-C will mobilize a large group of academic and government collaborators to improve ECCC's open source community model, the Canadian Land Surface Scheme including Biogeochemical Cycles (CLASSIC). CLASSIC is the land component of ECCC's family of Earth System Models used by the climate science, impacts, and adaptation communities. The four areas of CLASSIC to be developed to better represent Canada's carbon budget are: 1) boreal forests, 2) peatlands, 3) Arctic ecosystems, and 4) disturbance impacts on these ecosystems. COHERENT-C will be the first attempt at a comprehensive process-based modelling of Canada's terrestrial carbon cycle and will be used to predict how the carbon sink and source status of our managed and unmanaged lands may change in the future. These efforts are aimed at supporting ECCC's implementation of the Pan-Canadian Framework on Clean Growth and Climate Change and inform strategies to meet Canada's international commitments on climate change mitigation and sustainable development.

加拿大国家陆地碳循环优化高分辨率表示 (COHERENT-C) 项目是加拿大学术碳科学界与加拿大环境与气候变化部 (ECCC) 之间的合作项目。该项目的主要目标是随着气候、扰动和大气温室气体浓度的变化，迅速提高加拿大代表和预测加拿大陆地碳循环的技能。该项目的成果将包括 1) 为政策制定者提供关于加拿大碳汇和碳源过去和未来状况的年度摘要，以及 2) 详细介绍对加拿大森林、湿地碳循环过程脆弱性的深入了解的科学出版物和演示文稿和北方。 通过解决这些知识差距，我们将支持加拿大利用基于自然的解决方案来应对气候变化，并提供全国适应气候变化所需的气候预测。为了实现这些成果，COHERENT-C 将动员一大批学术和政府合作者来改进 ECCC 的开源社区模型，即包括生物地球化学循环 (CLASSIC) 在内的加拿大陆地表面计划。 CLASSIC 是 ECCC 地球系统模型系列的陆地组成部分，供气候科学、影响和适应社区使用。为了更好地代表加拿大的碳预算，将开发 CLASSIC 的四个领域：1) 北方森林，2) 泥炭地，3) 北极生态系统，以及 4) 对这些生态系统的干扰影响。 COHERENT-C 将是对加拿大陆地碳循环进行基于过程的综合建模的首次尝试，并将用于预测我们管理和非管理土地的碳汇和源状态未来可能发生的变化。这些努力旨在支持 ECCC 实施泛加拿大清洁增长和气候变化框架，并为履行加拿大在减缓气候变化和可持续发展方面的国际承诺提供战略依据。
