Prediction and Research Moored Array in the Tropical Atlantic

Meeting PIRATA-24/TAV

24th Prediction and Research Moored Array in the Tropical Atlantic /Tropical Atlantic Variability Meeting

Postponed - New Dates to be Determined

Miami, FL


The Prediction and Research Moored Array in the Tropical Atlantic/Tropical Atlantic Variability (PIRATA/TAV) meeting is held approximately once per year and welcomes participants from around the world. The last meeting took place October 22-24, 2018 in Marseille, France, PIRATA 23 and 2nd TAOS Review Workshop.

Meeting Objectives

PIRATA and the broader TAOS have evolved considerably over the past two decades in response to changing research and operational needs. This progress would not have been possible without strong international commitment to PIRATA and the collaborative nature of the PIRATA and TAV communities. The main goal of the meeting is to advance tropical Atlantic science by bringing together a diverse group of tropical Atlantic researchers and stakeholders.

Recently, assessments of TAOS were made through a CLIVAR review, Tropical Atlantic Observing System Review and several tropical Atlantic focused OceanObs’19 white papers. These review efforts put forward a series of recommendations for tropical Atlantic observations and science. We plan to discuss how the PIRATA/TAV community can implement some of those recommendations.

Prediction and Research Moored Array in the Tropical Atlantic (PIRATA) is a multinational program initiated in 1997 in the tropical Atlantic to improve our understanding and ability to predict ocean-atmosphere variability. PIRATA consists of a network of moored buoys providing meteorological and oceanographic data transmitted in real time to address fundamental scientific questions as well as societal needs.

The network is maintained through dedicated yearly cruises, which allow for extensive complementary shipboard measurements and provide platforms for deployment of other components of the Tropical Atlantic Observing System.

This paper describes network enhancements, scientific accomplishments and successes obtained from the last 10 years of observations, and additional results enabled by cooperation with other national and international programs.

Capacity building activities and the role of PIRATA in a future Tropical Atlantic Observing System that is presently being optimized are also described.

New: the story of the PIRATA rise

The rise of PIRATA 1995-2005


The PIRATA project is a joint effort between Brazil, France and the United States to collect oceanic and meteorological observations in the tropical Atlantic.

The experimental program PIRATA (initially « Pilot Research moored Array in the Tropical Atlantic » and named « Prediction and Research Moored Array in the Tropical Atlantic »  from 2008) has been implemented in 1997 in the Tropical Atlantic Ocean (Servain et al. 1998). It has been launched in the framework of the international program CLIVAR (CLImatic VARiability and predictability) and implies scientific teams from three countries: France (IRD, in charge of coordination and oceanic cruises, Météo France, with contributions by IFREMER and CNRS/INSU), Brazil (DHN and INPE) and USA (NOAA/PMEL). Financial supports for the program are from the IRD, Météo France, and Observatoire Midi-Pyrénées/Université Paul Sabatier.
