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

最近数据集的激增使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)。世界气候研究计划署的耦合建模工作组对观测评估和数据集可用性提出了新的要求，以评估即将到来的耦合模式比较项目第五阶段(CMIP5)模式的运行。该项目将建立和维护一个基于网络的、与环境管理机制评价相关的选定气候数据集的知情指南。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实用性和局限性提供“专家-用户”指导和建议。将讨论地球系统的每个组成部分，包括大气、海洋、陆地、冰冻圈和生物圈。广泛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。该互动网站预计将提高研究人员和学生了解数据限制并在研究中有效利用数据的能力。该项目将促进和加强相关气候数据档案的获取，以便从系统的角度对环境影响管理进行诊断分析和评价，包括参加即将举行的政府间气候变化专门委员会第五次评估报告(AR5)和CMIP5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.
