TRITON Data

Japan Agency for Marine-Earth Science and Technology (JAMSTEC) has developed Triangle Trans-Ocean Buoy Network (TRITON) buoy in 1998, and nearly 20 moorings have been deployed in the western tropical Pacific and eastern tropical Indian Ocean. These moorings in Pacific Ocean make Tropical Atmosphere Ocean (TAO)/TRITON array in cooperation with Pacific Marine Environmental Laboratory (PMEL) and National Data Buoy Center (NDBC) in National Ocean and Atmospheric Administration (NOAA) in United States. On the other hand, the moorings in Indian Ocean make Research moored Array for African-Asia-Australian Monsoon Analysis and prediction (RAMA) array as a multinational effort for Indian Ocean Observing System. These arrays are a part of Global Climate Observing system (GCOS), Global Ocean Observing System (GOOS) and Global Earth Observing System (GEOSS). Each buoy measures temperature, salinity, mixed layer currents for oceanic variables, and wind temperature, relative humidity, barometric pressure, precipitation and short wave radiation for meteorological variables. These measured variables is essential for monitoring, understanding and forecasting of short-term climatic phenomena, such as El Nino and southern oscillation and Indian Ocean dipole event. Data and graphic displays from these arrays are updated every day, and freely available to use for research, operational forecasting, educational activities and so on.

日本海洋研究开发机构（Japan Agency for Marine-Earth Science and Technology, JAMSTEC）于1998年研发了三角跨洋浮标网（Triangle Trans-Ocean Buoy Network, TRITON）浮标系统，目前已在热带西太平洋及热带东印度洋部署了近20套锚系浮标。其中部署于太平洋的锚系浮标，与美国国家海洋和大气管理局（National Ocean and Atmospheric Administration, NOAA）下属的太平洋海洋环境实验室（Pacific Marine Environmental Laboratory, PMEL）及国家数据浮标中心（National Data Buoy Center, NDBC）合作，共同组建了热带大气海洋（Tropical Atmosphere Ocean, TAO）/TRITON阵列。另一方面，部署于印度洋的锚系浮标则作为印度洋观测系统的多国协作项目，构建了亚非澳季风分析与预测研究锚定阵列（Research moored Array for African-Asia-Australian Monsoon Analysis and prediction, RAMA）。上述阵列均为全球气候观测系统（Global Climate Observing System, GCOS）、全球海洋观测系统（Global Ocean Observing System, GOOS）以及全球地球观测系统（Global Earth Observing System, GEOSS）的组成部分。每座浮标可观测两类要素：海洋要素包括海水温度、盐度与混合层流场；气象要素包括气温、相对湿度、气压、降水量及短波辐射。这些观测数据对于厄尔尼诺-南方涛动、印度洋偶极子事件等短期气候现象的监测、机理理解与预报工作至关重要。各阵列的观测数据与图形展示每日更新，可免费开放用于科研、业务预报、教育等相关活动。如需获取更多详细信息，请访问TRITON与IOMICS官方网站：TRITON：http://www.jamstec.go.jp/jamstec/TRITON/real_time/；IOMICS：http://wwwjamstec.go.jp/iorgc/iomics/
