The GCOS Second Report on the Adequacy of the Global Observing System - April 2003 Authors: GCOS, in collaboration with the Global Terrestrial Observing System (GTOS), the World Weather Watch (WWW) with its Global Observing System (GOS) and the Global Atmosphere Watch (GAW). Scope: international, regional, national and individual activities to be coordonated internationally Aim of the report: report on the adequacy of the global observing systems for climate; establishing the scientific requirements for systematic climate observations. The goals of this Report were to determine what progress has been made in implementing climate observing networks and systems since the first report; determine the degree to which these networks meet with scientific requirements and conform with associated observing principles; and assess how well these current systems, together with new and emerging methods of observation, will meet the needs of the UNFCCC. Annex lists key climate variables and describes systems (available and potential)

GCOS Implementation Oct 2004 Exact same Climate Variables as 2 nd adequacy report –Assigned priorities, and specified actions Criteria to assign current or near future priority: –Significant and citable benefits towards meeting…….blah blah… in support of impact assessment, prediction and attribution of climate change and the amelioration and/or adaptation. –Feasibility of an observation availability of acceptable accuracy and resolution in time and space. –Tractable set of implementing actions –Cost effective Lists specific ‘Actions’ for example: Maintain current glacier obsv. sites, add more in S. America, Africa, Himalayas & NZ Who: Parties national agencies coordinated by GTN-G WGMS, USGS & IGOS-P Cryo. ‘Obtain integrated analysis of snow cover over both hemisphersw. Who: Space agencies thru CliC & IGO-P cryo……

CEOS response to GCOS implementation ”CEOS identifies what can be achieved by better coordination of existing and future capabilities as well as those improvements that require additional resources and/or mandates beyond the present capacity of space agencies. This report is intended to initiate action and assist the Parties in advising and commenting on the planning actions within the agencies.” Specifically respond to actions in the implementation plan. For example Action O-2: Relevant CEOS space agencies will consult with the science community on appropriate retrieval algorithms of passive microwave observation for reprocessing sea ice products ………….

ICARP Working Group 7 report on cryospheric and hydrological processes and systems. Community document written for research planning purposes. Focuses on Arctic terrestrial, Coordinate large number of relatively independent projects. Data monitoring recommends super sites (CEOP?) and roving sites. Snow, recommend glacier inventory (GLIMS/surface area), mass balance of selected glaciers and Greenland. Toward an Integrated Arctic Observing Network, from the National Research Council No specific recommendations, cryosphere not addressed explicitly. Still at the idea stage. AOSB-CliC Observing Plan for the International Polar Year IPY proposal for Arctic Ocean Observing System. iAOOS. What is described is a plan not necessarily the plan. Nice diagrams of observing system. EuroGOOS Arctic Task Team Planning Document Focused on ocean, not many specifics still at ideas stage. Arctic Planning/IPY

Socioeconomic Data The Theme intends to create a framework for improved coordination of cryospheric observations conducted by research, long-term scientific monitoring, and operational programmes, and to generate the data and information needed for both operational services and research. ICSU report on socioeconomic data. Greater coordination and analysis are needed to aggregate, link, and grid socioeconomic data collected at the local or national level to larger scales, including global datasets. IGOS should improve its access to information about socioeconomic data in relevant Themes. This should take place with the appointment of individuals who are knowledgeable about socioeconomic data to specific Theme Teams.
