Climate Components of:
Coral Reef Monitoring (e.g., Hotspot Monitoring)Coastal Observations (e.g., IOOS)Other Paleoclimate ProxiesCarbon Flux (FLUXnet)Hydrology (GTN-H) [proposed]Permafrost (GTN-P)Glaciers (GTN-G)
US/NZ Bi-Lateral Climate Activities of Interest to the NDSC
• Bi-Lateral Climate Change Partnership signed July 2003
• 9 out of 26 proposals involve NOAA and NIWA; 7 of the 9 addressspecific observing projects as follows:
• Proposed Flask Sampling From a Ship Plying The Western Pacific for CO2 Measurements in the Southern Ocean
• Stratospheric Water Vapor Profiles at Lauder
• Dobson Spectrophotometer Measurements of Stratospheric Ozone
• Network for the Detection of Stratospheric Change (NDSC)
• Surface Ozone Measurement Project at South Pole
• Improved climate monitoring systems for the Pacific (GCOS)
• Improved ocean climate observations for the Pacific (GOOS)

PI-GCOS Implementation
• Regional GCOS Implementation Plan Developed (Finalized but stillin draft form)
• Prioritized list of 31 Projects in 5 Objective Areas• Advocacy• Sustaining Operational Observing Networks• Managing and Exchanging Regional GCOS Data• Accessing and Developing Products and Services• Building Capacity for Long-Term PI-GCOS Sustainability
• Selected Projects With Identified Funding• Regional GCOS Coordinator [US] • Demonstration Project for GCOS [NZ] • Expanding the Use of Climate Prediction [BoM] • Maintenance Support [US]• Pacific Data Portal
• Scope of the other 27 Pacific Island GCOS Projects is in the range of $24M (US) over the period from 2003 through 2008
