2: PIRATA2: PIRATA(Pilot Research moored Array in the Tropical Atlantic)

(1997 - 200?)Tripartite Programme

as a contribution to CLIVAR, GCOS and GOOS :- FRANCE (IRD & Météo-France)

- BRAZIL (INPE & DHN)- USA (NOAA/PMEL & AOML)

* 1997-2001 : « Pilote » period* 2001-2006 : Consolidation period• 2006-2008 : continuation… PIRATA has actually been under review process (positive…) by CLIVAR and Ocean Observations Panel for Climate -OOPC- in 2006 • 2007: New Memorandum of Understanding Define the commitments of the partners for thenext years…

PIRATA evolution from 1997 until nowPIRATA evolution from 1997 until now

PIRATA ATLAS buoys network in October 2005

(Brazilian SW extension => 13 buoys)

PIRATA ATLAS buoys network from June 2006

US NorthEast extension along 23°W(carried out by NOAA, R/V Ron Brown in June 2006)

BCLME & South AfricaSouthEast extension at 6°S-8°E(carried out by IRD, R/V L’Atalante in June 2006)

=> 16 ATLAS buoys actually operationnal

First PIRATA ATLAS buoys network in 1997

(12 then 10 buoys)

PIRATA network status:

Maintained by Brazil: 8 Atlas buoys Maintained by France : 6 Atlas buoys+ At 23°W-Equator : surface ADCP mooring since 2001

Maintained by USA : 4 Atlas buoys : 2 deployed in 2006,at 4N & 11N/23W, 2 at 20N/23W & 38W will be deployed in 2007

Ocean Sites reference flux (swr, lwr, rh, air T, SLP).
