1. WA-06-05:  Title: Initiate the creation of a coordination mechanism within GEO for global in-situ water observations, including ocean observations, and advocate synergy and sharing of infrastructure among observing systems.  PoC: A.G. de BRITO, University of Minho, Portugal  Members: WMO, GTOS, FAO, PORTUGAL, GERMANY, JAPAN, SPAIN, UNESCO, NETHERLANDS, WCRP, ARGENTINA, CEOS, IGOS-P, IOC, NIGER, NORWAY, RUSSIA, THAILAND

2. WA-06-05: Description 1. Produce an inventory of in-situ networks, their logistical infrastructure and potential for synergies with other in-situ measurements. See AR-06-07 and AR-06- 08 concerning water observations. 2.Based on the result of GEOSS Water Cycle Observation Workshop in November 2005, provide input to the new Observations Council on in-situ water cycle observations and assess the degree to which recommendations are acted upon. 3.Establish a process for providing input to this group on an on-going basis.

3. WA-06-05: Description (additional strategy)  4. Enhance the water cycle observation capability for monitoring long-term changes in the global water system and their feedback into the climate system.  5. Improve the interoperability of observing systems, and standardization of metadata for data sharing of crucial data for sustainable development of water resources and improvement of water management practices  6. Make progress in product development of the global near real-time river runoff network, advocate sharing of telecommunication infrastructure and joint know-how.

4. WA-06-05: Proposed milestones for the short term:  24.04.07 – define a new strategy to get information and stimulate the active collaboration from all the Task members;  04.05.07 – contact the task WA-06-05 members, according to the new approach strategy;  01.06.07 – analyse the received information and organize it according to the new approach strategy, in order to look for synergies between projects, areas and organizations and to enhance the inventory of in-situ networks and infrastructures;  07.06.07 – send the preliminary version of the Task Sheet to the ADC co-chair;  22.06.07 – send the updated Task Sheet to the GEO Secretariat.

5. © GEO Secretariat WA-07-02: Satellite Water with In-situ Data Quantity Measurements and Integration Develop an operational mechanism to provide water level observations in rivers, lakes/reservoirs and estuaries from satellite observations to support the upgrade of deficient run-off water gauge networks. Combine different types of satellite data that are relevant for water quantity measurements (snow water equivalent, streamflow) with in-situ observations for better accuracy and global coverage. Produce an implementation plan for a broad and operational global water cycle data integration system that combines in-situ, satellite data and model outputs. An international symposium is proposed to be held to assess techniques and their maturity for transitions to operations. A workshop is planned in 2007.
