Observations Programme Area Challenges SOTSOT –Integration of SOOP, VOS, ASAP –Integration of emerging CO2 program –Implement 200 VOSClim ships –Increase XBTs from 22,000 to 32,000 GLOSSGLOSS –Improve station reporting -- only 168 of 290 stations report regularly –Implement GPS at altimeter cal and long term trends subsets stations ArgoArgo –25 % of 3000 in place –Maintain funding long enough to complete array and demonstrate value [common to all]

Challenges (continued) DBCPDBCP –Increase from 800 to 1250 drifters –Extend the Tropical Moored Buoy Network across the Indian Ocean –Future integration of emerging Ocean Observatories Observations Program AreaObservations Program Area –System monitoring and performance reporting –Funding to meet implementation targets

Observing System Status: 2003, Q2. Sea Surface Temperature Performance Measure: Reduce the error in global measurement of sea surface temperature. Metric: Estimated maximum monthly mean error in 5  regions (degrees Celsius) Year  C Goal: 0.3  C Drifting Buoys Moored Buoys Ships Total Goal: 100% Global Coverage Goal: All boxes blue

Challenge: Deployment plan for maintaining continuous sampling in all 5-degree boxes.

Challenge: Future Integration of Emerging Ocean Observatories Network Sites identified by Int’l Time Series Science Team
