1. 2: 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 the next years… Photo: A.Kartavtseff

2. PIRATA 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 Africa SouthEast 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)

3. 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).

11. Oceanic cruises in May-July 2006 3 2 1 During the three quasi-simultaneous cruises: a) radiosounding profiles have been transmitted in real time by GTS (=> ECMWF…) b) temperature XBT profiles (0-800m) + temperature/salinity CTD profiles (0-500 or 1000m) have been transmitted in quasi-real time (at least daily) (also for CORIOLIS/ARGO and MERCATOR/GODAE projects). (radiosoudings at least twice a day from each vessel => about 250 profiles) (XBT profiles every ½° to 1° from Atalante and Ron Brown => about 250 profiles) (CTD profiles every ½° along meridional sections at 35°W, 23°W, 10°W, 3°E and 6°E => about 300 profiles) 1) Real time data:
