Critical Partners contributing resources Observations & Monitoring Program Critical partners contributing resources All observing activities supported by the Climate Observation Division are in partnership with other countries, including: • Argo: 34 countries • Arctic : 13 countries • Global Sea-Level System: 57 countries • Surface Drifters: 14 countries • Tropical Moored Buoy Arrays: RAMA (15) and PIRATA (3) International partnership and coordination is the most economical and sustainable pathway to achieve global observation coverage “The substantial commitment of NOAA to support in situ and satellite observations of ocean climate has been critical to building a Global Ocean Observing System. GOOS is delivering data and information for research and services to all Member States of the Intergovernmental Oceanographic Commission to help manage our relationship with the natural system and to build a sustainable future.” Albert Fischer, Ph.D. Director, GOOS Project Office
Observations & Monitoring Program Arctic Research • Arctic Research produces unique and multi-disciplinary observations for the Arctic region, including: • Bering Straight/Chukchi Sea/Pacific Arctic, heat, fresh water and ecosystem changes; • Sea-ice drift and ice mass; • Time series of essential climate variables • at Atmospheric Observatories • International partnerships • (Russia, Canada, Pacific Arctic Group) Recent Highlights: • NOAA’s Arctic Vision and Strategy (2011) • Sea-Ice Forecasting Workshop (2011) • CPO/Arctic priorities embedded in NOAA, IARPC and NOC plans (2012) • Arctic Council Marine Monitoring Plan FY12 Milestones: • Arctic Report Card • Quadrennial RUSALCA cruise in Bering Straight and Chukchi Sea Observing, understanding, and prediction of the Arctic where the environment is particularly sensitive to climate variability and change. 19
Observations & Monitoring ProgramMonitoring Activity: Detection and Attribution • Detection and Attribution projects are aimed at providing data and tools needed to make authoritative statements about the degree to which man-made influences are showing up in the climate system. These projects produce research publications and attribution knowledge and capabilities. • Recent Highlights: • Extension of attribution studies beyond initial global-scale atmospheric temperature to address regional scales and other variables, e.g. precipitation • Increased attention to the occurrence and attribution of single events that have large impacts on society (e.g., weather and climate extremes) • Partnerships: With DOE, support grants in detection/attribution and international scientists participating in the International Detection and Attribution Group (IDAG) • Opportunities: • Detection: support monitoring of historical extremes and compare with model projections of future extremes • Attribution: forge new alliances to address key issues (CPO programs, other agencies, international research institutions). • FuturePhases: • Maintain core detection/attribution focus but continue to expand into new areas like impacts attribution and event attribution. • Support emerging activity of the ESRL-led Attribution of Climate-related Events group, with a focus on establishing routine attribution “A key challenge for the community is to move beyond research-mode case studies to develop systems that can deliver regular and timely assessments in the aftermath of extreme events.” —Scott, et. al. “Attribution of Weather and Climate-Related Extreme Events. Published in Nature: September 8, 2011 20

Highlights Observations & Monitoring Program Program Health • Budget (past, present, and future) • External Forces • Risks • Concerns 22
Observations & Monitoring Program Budget Division Spending FY12 (FY11) Diane Stanitski, Candyce Clark, Sidney Thurston, Joel Levy, Steve Piotrowicz John Calder, Kathy Crane Chris Miller, Bill Murray Summer Intern: Amanda Laurier 23
Observations & Monitoring ProgramFY12 Budget Reduction Impacts • Small budget reductions in many observing activities. Nearly all global observing capabilities maintained (but with increased risks and reduced scientific involvement). XBT program focused reductions. • Significant reductions in support of ocean data assimilation (primarily at GFDL, NCEP) • Reduced support of some technology development • Analysis efforts reduced. A few product and analysis activities zeroed. • Maintained some investment in deep Argo technology development 25
Observations & Monitoring ProgramProspects for FY13 • President: $4.6M increase for COD • Senate: CPO funding = President’s budget • House: CPO funding = FY12 less $18M, “Committee recommends a more balanced funding allocation across NOAA’s research programs”…???? • Outcomes at COD level: ??? 26
Observations & Monitoring ProgramCapabilities and Risks • We’ve heard the message: Several years of stagnant budget are eroding capabilities and increasing risks • Risks include loss of data, instrumentation, spares (thereby increasing risks of observing cessation), personnel, data quality and timeliness, etc • Not everyone has indicated that risks have increased • Program managers will assess this information as we start planning for FY13 and beyond 27
Observations & Monitoring ProgramPerceptions (as the incoming director) • A collection of activities… the observing “system” is not uniformly developed or organized • However, many pieces are highly efficient and overall the system has made tremendous progress towards the global ocean observing system vision • There is no clear prioritization of observing activities • Demonstrating and communicating value/impact of current/future system sometimes difficult and not a part of our DNA • Program information not available online • Data search/access sometimes a challenge 28
Observations & Monitoring ProgramConcerns (after a year) Sustainability of the Observing System • It’s complex, has a lot of moving and aging parts, needs lots of love and care…. Maintenance and “refurbishment” become more important as time goes on. Expectations that COD will provide product and science support conflicts with mandate to sustain observing system (need both). Downward Budget Pressure • Overall federal budget will likely remain flat or decline for next few years. Observations are an important NOAA activity. But NOAA is challenged to support current and planned observing needs. NOAA is assessing and prioritizing its observing systems. Declining NOAA Fleet and Charter Fund resources • Requirement for global-class ship capability will remain for foreseeable future- Without adequate ship resources, parts of the global ocean observing system for climate that have been developed over the past 15 years are in peril (Tropical arrays, carbon buoys, deep ocean hydrography, etc). How does the program initiate new things and new technology (in light of above) 29
Highlights Observations & Monitoring Program Considerations for the Future • Where are we going? • Addressing program needs (what should we do!) 30

Observations & Monitoring Program Translating Increased Observing into Impacts • Observing, Understanding, Predicting, and Monitoring • Sea level • Ocean carbon sources and sinks • The ocean’s storage and global transport of heat and fresh water • Sea surface temperature • The air-sea exchange of heat and fresh water • Sea ice extent • Ocean biological changes associated with environmental changes (e.g. in Arctic) • Impacts on Products and Immediate Customers • Metrics/diagnostics (and their uncertainties), products, models (uptake and results) • Value beyond • Climate variability and change (e.g. ENSO, MJO, Monsoons, Indian Ocean Dipole, decadal and longer variations), extremes, inundation, floods, droughts, hurricanes, ecosystems, agriculture, commerce, safety, policy, etc Global Average Sea Level Change Ocean Storage of CO2 World Ocean Heat Content Global Average Sea Surface Temperature Arctic Sea Ice Extent 32 National Oceanic and Atmospheric Administration (NOAA)
Highlights Observations & Monitoring Program Addressing Program Needs Resources • THERE WILL BE OPPORTUNITIES! Be Prepared! • Develop strategic perspective (Wed morning) overall and within individual program activities. What initiatives are ready for FY14/15? • Improve the scope and availability of information and reporting (ie metrics) characterizing health, status, performance, and impacts of our activities (Wed morning) • Program activities and performance should be more strongly tied to science/research/monitoring goals. Develop a means to review programs to provide feedback and assess progress on these goals. Some programs may have to be terminated. • Look for opportunities to partner with other programs to expand observing capabilities (e.g. bio-Argo with Argo, CCE moorings, etc) 33
Highlights Observations & Monitoring Program Addressing Program Needs Resources (2) • Develop a portfolio of program impact materials describing impacts/value of observing efforts • Improve awareness and encourage support (and corresponding budget) within NOAA and elsewhere for research/obs activities (communications, messaging, and engagement) • Keep fighting internally for appropriate ship resources • Increased attention to potential bilateral “Resource Sharing Agreements” for ship time • Look for efficiencies/alternate strategies for ship scheduling for mooring servicing • New technologies may help (and may an attractive “sell” to NOAA if they help reduce reliance on ships), but introducing them into climate observing system has to be done carefully – what is our strategy and timeline for developing, considering, and incorporating evolutionary and revolutionary technologies? (Wed PM) IOOS Summit 34
Highlights Observations & Monitoring Program Addressing Program Needs Sustaining the System • Define what it takes to be sustainable, e.g. best practices/attributes of a sustained observing activity. • Identify those activities that should be “sustained” and those that are still in pilot or pre-sustained status Needs More Attention • Real-time data needs, assimilation & analysis Outward Focus • Provide program information (COD lead) • Develop data management roadmap to long-term goal of improving search and accessibility, bringing some consistency across data systems • Increase ties between global ocean observing system and communities developing observing capabilities for coasts, polar areas, living marine resources, and other locations and communities where climate impacts are acute and evident and where global ocean observations are useful 35
