10. GCOS Continuous Improvement & Assessment Cycle The GCOS programme has started the process for: a 2015 report on the progress and status of climate observation a new “Implementation Plan” in 2016, which should identify: −continuing and new requirements, including a restatement of the rationale for the list of ECVs and possible amendment of the list −the adequacy of present arrangements for meeting the requirements −the additional actions needed, with indicative costs, performance indicators and potential agents for implementation statements of specific requirements for products −from both in situ networks and the space-based component −and from integration of the data provided by both either embedded in the main Plan or as separate supplement(s)

11. Input to the new assessment Content will be based on various inputs, including from: 2011 WCRP Conference and 2013 SPARC Data Workshop 2013/2014 IPCC Fifth Assessment Report 2013/2014 national reporting to UNFCCC on systematic observation 2014 EUMETSAT/WCRP Climate Symposium WMO (GFCS, WIGOS), IOC (GOOS) and post-2015 GEO planning CEOS/CGMS/WMO initiatives (Architecture, Inventory of datasets) other assessments of requirements (GEO, ESA CCI) assessments by GCOS/WCRP panels dedicated GCOS workshops an open review

14. Implementation Plan (what kind of observations are needed ?) (Excerpt)

15. What needs to be measured – by whom? (Excerpt)

16. Developed Countries: ‑ improved climate observation capabilities, ‑ limited progress in resolving financial issues related to long-term continuity Developing Countries: ‑ limited (in-situ) progress, with decline in some regions, ‑ capacity building support remains small in relation to needs Much remains to be done: GCOS Progress Report 2004-2008 Satellite agencies : ‑ improved mission continuity and capability ‑ increasingly meeting climate needs Progress made, but: ‑ Many gaps persist, ‑ Continued int’l engagement needed for coordinated implementation and long-term continuity

17. Good progress with availability, quality and exploitation of data from satellites for climate purposes across the range of ECVs, from basic meteorological variables to radiation and atmospheric composition Good progress in general with in-situ meteorological networks, and support through the system improvement programme has helped maintaining a baseline; however, overall progress in developing countries has been limited GCOS Progress Report 2004-2008 – Atmosphere Some specific issues persist (e.g., measurement of precipitation, clouds, snow depth; precipitation data exchange; sunshine obs; metadata) Good progress in advancing climate reference networks Improved planning and progress with implementation of atmospheric composition networks meeting climate needs

18. Useful progress in almost every action called for in the Plan, but many actions remain incomplete. The ice-free upper 1500 m of the ocean are being observed systematically for temperature and salinity for the first time in history. Most in-situ networks have made progress (e.g., tide gauges, moored reference sites, tropical moored arrays, full ocean depth observations) Most in-situ observing activities continue to be carried out under research agency support and on research programme time limits. Important progress in provision of critical ocean satellite data of sea surface ECVs has been made, but not for all variables, and data access remains to be ensured. Important progress in development of historical ocean reanalysis and in high resolution ocean forecasting capabilities. Promising developments in improved methods and standards will allow wider measurement of biological and chemical ECVs and consideration of new ECVs in the years ahead. Data sharing remains incomplete, particularly for tide gauges and biogeochemical ECVs. Data archaeology needs to continue. GCOS Progress Report 2004-2008 – Oceans

19. GCOS Progress Report 2004-2008 - Terrestrial Increasing significance and recognition of terrestrial data for climate change adaptation and impact studies Good progress in defining standards for observation of terrestrial variables Slow take-up of institutional support for terrestrial climate observations has limited some in-situ progress Networks dealt with by research community show some good progress Progress towards establishment of Global Terrestrial Networks (GTN) for many of the ECV’s Good engagement of satellite needs including product development, reprocessing and continuity
