The Global Climate Observing System (GCOS) was established in 1992 as an outcome of the Second World Climate Conference, to ensure that the observations and information needed to address climate-related issues are obtained and made available to all potential users. The GCOS is co-sponsored by the World Meteorological Organization (WMO), the Intergovernmental Oceanographic Commission (IOC) of UNESCO, the United Nations Environment Programme (UNEP), and the International Council for Science (ICSU). In order to assess and monitor the adequacy of in-situ observation networks as well as satellite-based observing systems, GCOS regularly reports on the adequacy of the current climate observing system to the United Nations Framework Convention on Climate Change (UNFCCC), and thereby identifies the needs of the current climate observing system.

全球气候观测系统(GCOS)是在1992年作为第二次世界气候会议的成果建立的，以确保获得处理气候相关问题所需的观测和信息，并向所有潜在用户提供这些信息。全球气候观测系统由世界气象组织(WMO)、联合国教科文组织政府间海洋学委员会(IOC)、联合国环境规划署(UNEP)和国际科学理事会(ICSU)共同赞助。为了评估和监控现场观测网络以及卫星观测系统的充分性,全球气候观测系统定期向《联合国气候变化框架公约》(UNFCCC)报告当前气候观测系统的充分性,从而确定了当前气候观测系统的需要。

GCOS is a system that comprises the climate-relevant components of many contributing observing systems and networks. Its mission is to help ensure that these contributing systems, taken as a whole, provide the comprehensive information on the global climate system that is required by users, including individuals, national and international organizations, institutions and agencies. The programme promotes the sustained provision and availability of reliable physical, chemical and biological observations and data records for the total climate system - across the atmospheric, oceanic and terrestrial domains, including the hydrological cycle, the carbon cycle and the cryosphere.

全球气候观测系统包括许多有贡献的观测系统和网络中与气候有关的部分。 它的任务是帮助确保这些贡献系统作为一个整体，提供包括个人、国家和国际组织和机构在内的用户所需的全球气候系统的全面信息。 该方案促进针对全气候系统的可靠物理、化学和生物观测和数据记录的持续提供和可用性- -覆盖大气、海洋和陆地领域，包括水循环、碳循环和冰冻圈。  

Structure == 结构==

The primary observing systems contributing to the GCOS are the WMO Integrated Global Observing System (WIGOS), the Global Cryosphere Watch (GCW), and the World Hydrological Cycle Observing System (WHYCOS), and the Intergovernmental Oceanographic Commission-led Global Ocean Observing System (GOOS). A number of other domain-based and cross-domain research and operational observing systems also provide important contributions and encompass both in-situ and satellite observations. GCOS is both supported by and supports the international scientific and technical community, and the World Climate Research Programme (WCRP) co-sponsors the expert panels set up by GCOS for the atmospheric, oceanic and terrestrial domains. The composite observing system designated by GCOS serves as the climate-observation component of the broader Global Earth Observation System of Systems (GEOSS), and at the same time a number of specific observing-system initiatives of GEOSS contribute to the GCOS.

为全球海洋观测系统作出贡献的主要观测系统是气象组织综合全球观测系统(WIGOS),全球冰冻圈观测系统(GCW),和世界水循环观测系统(WHYCOS),和政府间海洋学委员会领导的全球海洋观测系统(GOOS)。 其他一些基于领域和跨领域的研究和业务观测系统也提供了重要贡献，包括现场观测和卫星观测。 全球气候观测系统同时得到国际科学和技术界的支持，并支持和支持国际科学和技术。世界气候研究计划(WCRP)共同赞助了全球气候观测系统为大气、海洋和陆地领域设立的专家小组。 GCOS指定的复合观测系统是更广泛的全球地球观测系统(GEOSS)的气候观测组成部分，同时全球对地观测系统的具体观测系统举措也促进了全球气候观测系统。

Essential Climate Variables (ECVs) ==基本气候变量-ECVs==

GCOS has identified 50 Essential Climate Variables (ECVs) considered to be feasible for global climate observation and to have a high impact on the requirements of the UNFCCC and other stakeholders. There is a strong need for sustained observation of these ECVs, as the observations are needed for the generation and updating of global climate products and derived information. GCOS and its partners are developing ways of improving the generation and supply of data products relating to the ECVs.

全球气候观测系统已经确定了50个被认为是全球气候观测可行的基本气候变量(ECVs) ，并对《联合国气候变化框架公约》和其他利益攸关方的要求产生了重大影响。 对这些基本气候变量的持续观测非常有必要，因为这些观测是生成和更新全球气候产品和派生信息所必需的。 全球气候观测系统及其合作伙伴正在开发改进与ECVs有关的数据产品的生产和供应途径。

Expert Panels ==专家小组==

Three expert panels have been established by the GCOS Steering Committee to define the observations needed in each of the main global domains - Atmosphere, oceans, and land - to prepare specific programme elements and to make recommendations for implementation. GCOS is both supported by and supports the international scientific community, and therefore the three expert panels are co-sponsored by the World Climate Research Programme (WCRP). The Atmospheric, Ocean, and Terrestrial Observation Panel for Climate gather scientific and technical experts in the respective areas to generate inputs from these fields to the climate observing community. Those expert panels report to the GCOS Steering Committee, and have been established to define the observations needed in each of the main global domains to prepare scientific programme-elements and to make recommendations for implementation.

全球气候观测系统指导委员会 设立了三个专家小组，以确定在每一个主要的全球领域（大气、海洋和陆地）所需要的观测，以编制具体的方案构成部分，并提出执行建议。 GCOS得到国际科学界的支持，也支持国际科学界。因此三个专家小组是由世界气候研究计划(WCRP)共同赞助的。 大气、海洋和陆地气候观测小组召集各领域的科学和技术专家，从这些领域向气候观测团体提供投入。 这些专家小组向全球气候观测系统指导委员会报告，设立这些专家小组的目的是确定在每一个主要的全球领域所需的观测，以便编制科学方案组成部分，并提出执行建议。

Networks= = 网络 = =

One of the first tasks of the GCOS programme was to define a subset of the World Weather Watch (WWW) stations appropriate for basic climate monitoring. The subset of roughly 1000 baseline surface stations became the GCOS Surface Network (GSN) ,while a subset of 150 upper air stations was designated as the GCOS Upper-Air Network (GUAN) .These were built on existing WMO classifications and became the initial baseline components of the atmospheric networks. Considerations for selection of GSN included spatial distribution, length and quality of record, long-term commitment, and degree of urbanization. Similar considerations were used for GUAN. Designation of these networks benefited both the GCOS and the National Meteorological and Hydrological Services (NMHS). For NMHSs, designation of a station as part of the global climate network helped sustain support for these sites with long-term records. The networks provided the foundation for the Regional Basic Climatological Network, which provides far greater spatial detail on the variability of climate.

全球气候观测系统方案的首要任务之一是确定适合于基本气候监测的世界天气观测站的子集。大约1000个基线地面站的子集成为 GCOS 地面网络(GSN) ，而150个高空站的子集被指定为 GCOS 高空网络(GUAN)。它们建立在现有的气象组织分类的基础上，成为大气网络的最初基线组成部分。选择 GSN 的考虑因素包括空间分布、记录的长度和质量、长期承诺和城市化程度。类似的考虑也适用于GUAN。指定这些网络有利于全球气候观测系统和国家气象和水文服务。对于国家气象和水文服务来说，指定一个气象站作为全球气候网络的一部分，有助于维持对这些有长期记录的站点的支持。这些网络为区域基础气候学网络 提供了基础，该网络提供了关于气候变化的更多空间细节。

Recognizing that a balance has to be struck between standards and completeness of ground-based measurement, the GCOS programme recognized a hierarchy of observational networks and systems, comprising comprehensive, baseline and reference networks based on assumptions of spatial sampling needs.

全球气候观测系统方案认识到必须在地面测量的标准和完整性之间取得平衡，认识到观测网络和系统的层次结构，包括根据对空间取样需要的假设而建立的综合、基准和参考网络。

An example of a particularly successful step forward in implementing a global observing system for climate is the initiation of a reference network for upper-air observations - the GCOS Reference Upper-Air Network (GRUAN). The network is the prototype of a hybrid observing system, combining operational upper-air measurement sites with research sites and providing high-quality reference data for atmospheric profiles. GRUAN sites are undertaking high-quality atmospheric profile measurements that will help understand trends in upper-air ECVs, assist in investigating processes in the upper-troposphere and lower stratosphere, and provide data for calibrating satellite measurements and validating independent climate analyses and models. At GRUAN sites, the principles of quality, traceability and complete error characterization have been heeded, for at least part of the observing programme. The network is planned to grow over its initial size of 15 stations in coming years; introducing climate quality standards to a larger number of sites.

在实施全球气候观测系统方面特别成功的一个例子是启动了一个高空观测参考网络——全球气候观测系统参考高空网络。该网络是一个混合观测系统的原型，将业务上的高空测量站点与研究站点结合起来，为大气廓线提供高质量的参考数据。全球气候观测系统参考高空网络各站正在进行高质量的大气剖面测量，这将有助于了解高空气候变化趋势，协助调查对流层上层和平流层下层的过程，并为校准卫星测量和验证独立的气候分析和模型提供数据。在 GRUAN 站点，至少部分观测程序遵循了质量、可追溯性和完整的错误描述的原则。该网络计划在未来几年扩大其最初的15个站点的规模; 在更多的站点引入气候质量标准。
