GTSPP全球温盐剖面计划（1985-2020）

全球温盐剖面计划（GTSPP）是IOC/IODE委员会和IOC/WMO全球海洋服务系统（IGOSS）委员会联合开展的一项计划。IODE和IGOSS分别是IOC和WMO的技术委员会。GTSPP计划的主要目标是向用户快速提供海洋温盐（T-S）观测资料，使用户能更容易得到这些资料。通过GTS传输的实时资料和美国NODC接收的延时资料都整合到一个持续管理的数据库（Continuously Managed Database）。澳大利亚、加拿大、法国、德国、日本、俄罗斯和美国为该计划做了大量工作，其中加拿大的海洋环境资料服务中心（MEDS）是该计划的牵头单位，负责收集并处理实时资料。MEDS通过GTS从几个源头收集实时资料，将资料传送给美国NODC前进行查错等处理；同时，MEDS开发了GTSPP数据的质量控制程序（见图9-1）。除加拿大MEDS和美国NODC，本计划还有3个科学中心，分别独立分析印度洋、太平洋和大西洋的延时数据集。它们是履行WOCE资料汇集中心职责的澳大利亚联邦科学、工业和研究组织（CSIRO），以及美国斯克里普思海洋研究所（SIO）和美国NOAA的大西洋海洋气象实验室（AOML）。关于更详细的信息，请参阅网址：http://data.nodc.noaa.gov/gtspp/The Global Temperature and Salinity Profile Program (GTSPP) is a joint initiative co-developed by the IOC/IODE Committee and the IOC/WMO Integrated Global Ocean Service System (IGOSS) Committee. IODE and IGOSS serve as the technical committees of the Intergovernmental Oceanographic Commission (IOC) and the World Meteorological Organization (WMO), respectively. The primary goal of the GTSPP is to rapidly provide oceanographic temperature and salinity (T-S) observational data to end users, thereby facilitating their access to these datasets. Real-time data transmitted via the Global Telecommunication System (GTS) and delayed-mode data received by the US National Oceanographic Data Center (NODC) are both integrated into the Continuously Managed Database (CMD). Australia, Canada, France, Germany, Japan, the Russian Federation, and the United States have made substantial contributions to this program. Among them, the Marine Environmental Data Service (MEDS) of Canada acts as the lead entity of the program, responsible for collecting and processing real-time data. MEDS collects real-time data from multiple sources through the GTS, and transmits these data to the US NODC for error checking and other processing prior to integration. Meanwhile, MEDS has developed quality control procedures for GTSPP datasets (see Figure 9-1). In addition to Canada's MEDS and the US NODC, the program has three additional scientific centers that independently analyze delayed-mode datasets for the Indian, Pacific, and Atlantic Oceans. These centers are the Commonwealth Scientific and Industrial Research Organisation (CSIRO) of Australia, which fulfills the duties of the WOCE Data Assembly Center, the Scripps Institution of Oceanography (SIO) of the United States, and the Atlantic Oceanographic and Meteorological Laboratory (AOML) under the US National Oceanic and Atmospheric Administration (NOAA).
