1. NOAA National Data Buoy Center Tropical Atmosphere Ocean Program Ocean Climate Observation System Review Thursday, October 28 th, 2010 NOAA National Data Buoy Center, Tropical Atmosphere Ocean (TAO) Program, Shannon McArthur, TAO Program Manager

2. “What impact would a 30% reduction in ship time on the Ka’imimoana have on the tropical Pacific ocean observing system, and what approach should be taken to continue monitoring and delivery of observing system data necessary for essential analysis and forecasting?” -NOAA/CPO’s Climate Observation Division CONTEXT

3. “What If Scenario” 30% Marine Service Reduction

TAKE AWAY ---- * 8 Service Missions per FY are needed to sustain 80% performance target * TAO Performance Impact Since FY04 : Loss 8%  10% * 30% reduction in ship time = 5 service missions per FY  55% (+/-10%) Data Availability "...the crowning achievement of TOGA was the development of the Tropical Atmosphere/Ocean (TAO) array..."
