海表温度（SST）的测量是业务的海洋和大气预报系统所需要的，以约束模拟的上层海洋环流和热结构。全球海洋数据同化实验（GODAE）高分辨率SST试点项目（GHRSST-PP）的启动是为了通过协调为全球提供准确、高分辨率的SST产品来满足这些需求。试点项目现已完成，但高分辨率SST（GHRSST）小组内的活动仍在继续。该试点项目侧重于协调各种卫星和现场数据流，这些数据流在以国际分发方式实施的区域/全球任务共享框架内进行索引、处理、质量控制、分析和记录。在GHRSST内开发的具有有意义误差估计的数据由R/GTS内的服务提供。目前，国际中心每天处理数TB的数据，产生超过25 GB的产品。每天生成EncantSST分析和异常SST输出，通过诊断输出提供SST分析的置信度。生成诊断数据集，并提供网络接口，以监测观测和分析产品的质量。GHRSST研究和开发项目继续解决仪器校准、算法开发、昼夜变化、皮肤温度偏差以及GHRSST产品的确认/验证等问题。GHRSST还与应用程序和用户密切合作，定期为SST用户和生产者之间的讨论和反馈提供论坛。GHRSST R/GTS框架内的所有数据均可免费获得。本文回顾了GHRSST-PP的进展情况，重点介绍了对试点项目成功至关重要的成就。
Sea surface temperature (SST) measurements are required by operational ocean and atmospheric forecasting systems to constrain modeled upper ocean circulation and thermal structure. The Global Ocean Data Assimilation Experiment (GODAE) High Resolution SST Pilot Project (GHRSST-PP) was initiated to address these needs by coordinating the provision of accurate, high-resolution, SST products for the global domain. The pilot project is now complete, but activities continue within the Group for High Resolution SST (GHRSST). The pilot project focused on harmonizing diverse satellite and in situ data streams that were indexed, processed, quality controlled, analyzed, and documented within a Regional/Global Task Sharing (R/GTS) framework implemented in an internationally distributed manner. Data with meaningful error estimates developed within GHRSST are provided by services within R/GTS. Currently, several terabytes of data are processed at international centers daily, creating more than 25 gigabytes of product. Ensemble SST analyses together with anomaly SST outputs are generated each day, providing confidence in SST analyses via diagnostic outputs. Diagnostic data sets are generated and Web interfaces are provided to monitor the quality of observation and analysis products. GHRSST research and development projects continue to tackle problems of instrument calibration, algorithm development, diurnal variability, skin temperature deviation, and validation/verification of GHRSST products. GHRSST also works closely with applications and users, providing a forum for discussion and feedback between SST users and producers on a regular basis. All data within the GHRSST R/GTS framework are freely available. This paper reviews the progress of GHRSST-PP, highlighting achievements that have been fundamental to the success of the pilot project.
