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.
