TAO/TRITON, RAMA, and PIRATA Buoys, Monthly, 1987-present, Potential Density Anomaly

Published by NOAA NMFS SWFSC Environmental Research Division | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: January 27, 2026 | Last Modified: 2022-09-02T00:00:00.000+00:00
This dataset has monthly Potential Density Anomaly (sigma-theta) data from the TAO/TRITON (Pacific Ocean, https://www.pmel.noaa.gov/gtmba/ ), RAMA (Indian Ocean, https://www.pmel.noaa.gov/gtmba/pmel-theme/indian-ocean-rama ), and PIRATA (Atlantic Ocean, https://www.pmel.noaa.gov/gtmba/pirata/ ) arrays of moored buoys which transmit oceanographic and meteorological data to shore in real-time via the Argos satellite system. These buoys are major components of the CLIVAR climate analysis project and the GOOS, GCOS, and GEOSS observing systems. Monthly data is an average of daily values collected during a month. A minimum of 15 daily values are required to compute a monthly average. This dataset contains realtime and delayed mode data (see the 'source' variable).
