  1. The NDBC Tropical Expansion: Overview and Emerging PIRATA Partnership Don Conlee Chief Scientist National Data Buoy Center Stennis Space Center, MS 39529

  2. Project Background • Congressional Supplemental following active 2004 U.S. tropical season (Dec. 05) • NCEP/NHC prioritized from 51 previously-identified NCEP locations of buoy needs • Enough Funding for 7 buoys • 6 new • Maintain Pensacola buoy scheduled for removal • Desired availability – Start of next Atlantic tropical season (1 June 05)

  3. Requirements/Priorities • Required: Continuous Wind Sampling, Surface Pressure, Waves • Desired: • SST, Air Temp, Humidity (Provided) • Upper Ocean Heat Content, Rain (Partial/Planned) • High Reliability/Survivability • Large Hulls (12m and 10m Discus, 6m NOMAD) • Quadruple Instrument Redundancy • 2 complete integration systems per buoy • Backup Communications (Goes + Iridium)

  4. 12m • Placeholder for some cool pics from Stuart.

  5. In the Locks…

  6. 10m Launch

  7. 6m NOMAD High Reliability Variant

  8. 12m (Yucatan) – Late April, Early May 10m (Central Carib.) – Late May 6m (Atlantic) – Late May

  9. WHOI NTAS PIRATA 38°W Line

  10. PIRATA Partnership • Tropical Expansion briefed at PIRATA-10 in Fortaleza, Dec. 2004 • Asked PIRATA SSC to consider desirability of “PIRATIZING” easternmost buoys. • Letter of 2 February asked NDBC to consider adding instrumentation, including subsurface • NDBC is accommodating on a non-interference basis with primary mission • Opportunity to test emerging capabilities and gain experience with tropical climate observation • Build relationship with PIRATA principals • Better satisfy original NWS/NCEP/NHC requirement

  11. “Piratizing”, Phase 1 • Add Rain and Precision SW Radiation to 6m NOMAD buoys • Add CT capability to small companion buoy • (ADCP and Dir. Waves = Lagniappe) • Enhanced calibration, add post-calibration • Associated Data Management and Distribution

  12. NDBC 1.8m Wave Buoy

  13. 1.8m with ADCP

  14. 1.8m w/CT String Mooring Design

  15. Next Steps • Deploy 1.8m companion at easternmost buoy if unable to include on CG initial deployment • Evaluate effectiveness with PIRATA • Use interface for rain and radiation to improve resolution and sampling • Add current meter at 10m

  16. More Climate Partnerships • Continuing and Expanding Radiation Observations on MON – WHOI • Provide NTAS data to NHC (no GTS/model input) • CO2 on Coastal MON buoy this summer –PMEL (Sabine)
