14. China national climate committee identified 16 climate-target regions of China

15. Current design of 260 National climate observatory network Over land, the great spatial heterogeneity requires detailed observations
What we can not see in this map is the gaps in temporal and variables. For spatial and temporal scales are inter-connected, we have to be very careful to make the specific variable observation with appropriate spatial and temporal resolution consistently. 15

16. UNFCCC
WMO is pleased that GCOS has received strong support from the UNFCCC and that this relationship has contributed to a substantial increase in the visibility of GCOS and, therefore, its parent bodies, thus enabling the GCOS Secretariat to more effectively represent the concerns, interests, and needs of the climate observing community. WMO encourages you to maintain, and indeed, strengthen your fruitful connection with the UNFCCC.

17. FAO / GTOS
WMO understands the desirability of inviting the Food and Agricultural Organization (FAO), which is the main sponsor of GTOS, to become a fifth sponsor of GCOS.
The terrestrial domain and the role of GTOS in meeting climate-related needs for observational data have assumed greatly increased importance, especially since the emergence of adaptation as a major thrust of the UNFCCC.

18. GCOS Reference Upper-air Network (GRUAN).
The WMO Executive Council has noted the recent establishment of the GCOS Reference Upper-air Network (GRUAN).
This network will provide high-quality observing sites for the atmospheric profile, including surface and upper-air measurements, in support of climate applications, validation of satellite products, and climate research.
We would like to remind the Steering Committee that the Council has requested an update on the progress of the selection of GRUAN sites, as well as minimum instrumentation requirements, at its sixty-first session in June 2009.

19. The tiered climate networks will be the real solution (GRUAN)
Benchmark Network

20. Satellite Observations for Climate
WMO has taken action through its Space Programme to respond at several levels to the space-related aspects of the GCOS Implementation Plan and in particular to its Satellite Supplement (GCOS-107).
The WMO Executive Council has agreed that the new Vision for the space-based Global Observing System should address climate observation needs among its core objectives and confirmed the high-level goal that there should be no gap in the satellite-based climate records, in accordance with the GCOS Climate Monitoring Principles.

21. Satellite Observations for Climate
The Global Space-based Inter-calibration System (GSICS) is reaching an operational stage and will ensure data comparability and homogeneity in the provision of Fundamental Climate Data Records.
Developments are underway towards an initial network of Regional Specialized Satellite Centres for Climate Monitoring (RSSC-CM) that will ultimately deliver routine products related to Essential Climate Variables. WMO is pleased to mention that an active collaboration is developing with space agencies, CGMS and CEOS on these initiatives in support of GCOS.

CEOS agencies will cooperate in developing future plans for an Ocean Salinity Constellation.

31. Developing countries
Developing countries have special problems, not least with respect to securing the resources needed to implement regional GCOS Action Plans.
The WMO Executive Council encourages the GCOS Secretariat and the GCOS Steering Committee to study the issue with a view to facilitating the necessary fundraising, including from the UNFCCC and its financial mechanism, to enable the effective implementation of these Plans.

32. Implementation
WMO recognizes that GCOS is still far from fully implemented and that a major effort is needed in most parts of the world to strengthen and maintain essential climate observing networks and systems.
In this regard, WMO would like to commend the development of the Regional Action Plans produced through the now-completed GCOS Regional Workshop Programme and also the follow-up initiatives, such as the Climate for Development for Africa Programme, intended to facilitate the implementation of needed improvements in developing regions.
WMO encourages the GCOS Steering Committee to continue such follow-up efforts as resources allow.

33. Climate Adaptation
WMO understands the need to pay increasing attention to the requirements for climate information for adaptation.
We would like to see the GCOS Steering Committee, in addition to WCRP and others, identify their current activities that are relevant to adaptation and also identify gaps in climate information in key socio-economic sectors that need addressing in order to enable effective climate-risk management.
The GCOS Steering Committee should take steps to address observational needs for adaptation in future priority setting and planning.

34. UNFCCC/GEOSS/WIGOS WCC-3
WMO notes that much has changed since the original 1992 Memorandum of Understanding (MOU) establishing GCOS was last updated in 1998:
the greatly strengthened link with the UNFCCC
the emergence of GEOSS
the establishment of WIGOS.
the agreement of WMO with ISO
the outcome of WCC-3 will have important implications for GCOS.

35. WMO and ISO strengthen partnership on international standardization
WMO and ISO have agreed to increase their cooperation in the development of international standards related to meteorological and hydrological data, products and services.
The WMO has liaison status with nearly 30 of ISO's technical committees developing standards with relevance to hydrometry, air quality, water quality, soil quality, geographic information, solar energy, petroleum and gas industry, information technologies, marine, quantities and units.
ISO Secretary-General Alan Bryden and WMO Secretary-General Michel Jarraud today signed an agreement on Working arrangements in Geneva, Switzerland, to formalize the partnership.
Geneva, 16 September 2008 – WMO/ISO

36. Agreement of WMO with ISO
The Working arrangements between the WMO and ISO aim to strengthen the development of International Standards and to avoid duplication of work on standards related to the following environmental data, products and services :
Meteorological
Climatological
Hydrological
Marine/Ocean and related
Procedures are now in place for the accelerated adoption by ISO of WMO documents as ISO standards. WMO and ISO will develop, approve and publish common standards based on WMO technical regulations, manuals and guides.

37. Agreement of WMO with ISO
Michel Jarraud, SG of WMO, stated that the new procedures “would clarify the authority of WMO documents and enhance their international recognition and dissemination.
Alan Bryden, SG of ISO, underlined that the agreement was an illustration of the increasing collaboration between the UN System and ISO, as well as of the contribution of international standards to responding to the challenges of climate change.
ISO has recognized WMO as an international standardization body through ISO Council Resolution 43/2007 approved in December 2007.

38. Challenges and opportunities

39. Need an Integrated Comprehensive Global Climate Observing System

40. MOU and GCOS PLAN
Considering all above changes , WMO therefore encourages the Steering Committee to assess the need for updating the GCOS MOU and that it propose to the Sponsors elements that they should consider in renegotiating and revising the MOU.
For similar reasons, WMO supports updating the 1995 GCOS Plan and encourages the Steering Committee to propose a process for accelerated completion of the Plan.
WMO recognizes the precarious and unstable nature of the GCOS Secretariat budget and will work with the other Sponsors of GCOS to ensure its long-term viability

41. Discussions: Sustained approach for GCOS
Any Single Problem Requires Many Data Sets
A Single Data Set Will Serve Many Communities
GEOSS is a global distributed system, including satellite observation systems, Global in situ networks and systems, And local and regional in situ networks.
GEOSS will deliver the benefits of EO to both data & information providers and consumers world wide.

42. Discussions : Sustained approach for GCOS
1. Sustaining current GCOS observing systems and merge other systems to make it stronger by using all available resources; (operational ?)
2. Developing new climate observing capabilities (both surface/deep ocean and space-based systems, comprehensive GCOS)
3.Providing climate products and services to end users, i.e. , from climate observation to climate monitoring and services. (Result-based approach, more visible way)
GEOSS is a global distributed system, including satellite observation systems, Global in situ networks and systems, And local and regional in situ networks.
GEOSS will deliver the benefits of EO to both data & information providers and consumers world wide.
