An Informed Guide to Climate Data Sets with Relevance to Earth System Model Evaluation

最近数据集的激增使得科学家个人很难知道哪些数据集最适合具体应用，包括评估和分析日益复杂和全面的地球系统模型（ESM）。世界气候研究方案耦合模型工作组提出了对观测评估和数据集可用性的新要求，以评估即将进行的耦合模型相互比较项目第5阶段（CMIP 5）模型运行。该项目将建立和维护一个基于网络的知情指南，介绍与评价无害环境措施有关的选定气候数据集。两个主要目标是：（1）评价和评估选定的气候数据集;（2）就选定的气候数据集的效用和局限性提供“专家-用户”指导和建议。地球系统的每一个组成部分都将被讨论，包括大气层、海洋、陆地、冰冻圈和生物圈。更广泛的意义知情指南旨在通过世界各地的大学和其他气候研究人员的广泛参与，作为社区资源。互动网站预计将提高研究人员和学生的能力，了解数据的局限性，并有效地利用数据在他们的研究。该项目将便利和加强获取相关气候数据档案，以便从系统角度对无害环境措施进行诊断分析和评估，包括参与即将发布的政府间气候变化专门委员会（气专委）第五次评估报告和CMIP 5活动的模型。

The recent proliferation of datasets makes it difficult for individual scientists to know which are most appropriate for specific applications, including evaluation and analysis of increasingly complex and comprehensive Earth System Models (ESMs). The World Climate Research Programme's Working Group on Coupled Modeling has led to new demands for observational assessments and dataset availability for evaluating the forthcoming Coupled Model Intercomparison Project Phase 5 (CMIP5) model runs. This project will establish and maintain a web-based Informed Guide to selected climate data sets of relevance to the evaluation of ESMs. The two main objectives are: 1) to evaluate and assess selected climate datasets, and 2) to provide "expert-user" guidance and advice on the utility and limitations of selected climate data sets. Each component of the earth system will be addressed, including the atmosphere, ocean, land, cryosphere, and biosphere.Broader SignificanceThe Informed Guide is intended to serve as a community resource through broad participation by university and other climate researchers worldwide. The interactive website is expected to enhance the ability of researchers and students to understand data limitations and effectively utilize data in their research. The project will facilitate and enhance access to relevant climate data archives for diagnostic analyses and evaluation of ESMs from a system perspective, including those models participating in the upcoming Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment Report (AR5) and CMIP5 activities.
