The NDBC Tropical Expansion: Overview and Emerging PIRATA
Partnership
Don ConleeChief Scientist
National Data Buoy Center Stennis Space Center, MS 39529
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)
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)
12m
• Placeholder for some cool pics from Stuart.

10m Launch
6m NOMAD High Reliability Variant
12m (Yucatan) – Late April, Early May10m (Central Carib.) – Late May6m (Atlantic) – Late May

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
“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
NDBC 1.8m Wave Buoy
1.8m with ADCP
1.8m w/CT String Mooring Design
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
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)
