The Prediction Research Moored Array in the Tropical Atlantic (PIRATA) is an in situ observation array of moored buoys designed to monitor a set of atmospheric and oceanographic variables of the ocean-atmosphere interface processes at the tropical Atlantic ocean.

The PIRATA project is a multinational cooperation program with participation of Brazil, France, and the United States. These three countries shared the tasks of implementation and maintenance of the array.

All moorings during the pilot study were built by NOAA's Pacific Marine Environmental Laboratory (PMEL), which is also responsible for shipping, calibration, laboratory check outs, and instrument refurbishment.

The responsibility for the logistic support for developing and maintaining the PIRATA moored array is shared between Brazil and France. Brazil takes care of the western half of the array and French, the eastern half.


PIRATA is recognized, supported, and recommended by the international scientific community and climate programs such as the CLIVAR and GOOS.
