Implementation Plan for the Global Observing System for Climate in Support of the UNFCCC (2010 Update) The internationally-designated data centres and archives that have been identified in the terrestrial domain are shown in Table 14. For the in situ observing networks, adequate sustained funding of the centres and their operation is required. Major components of the terrestrial domain observing systems are satellite remote sensing and the production of integrated analysis products. The space agencies and associated research organizations producing the analyses also provide the data management and archiving function. TOPC will need to monitor the data management and archive performance of this informal network to ensure that data and products are available and follow the GCMPs. Table 14.

This would facilitate access to multiple variables. GTOS has made considerable progress in the development of the Terrestrial Ecosystem Monitoring System (TEMS), a web portal for metadata on terrestrial in situ measurement sites, including biogeophysical variables addressed by each site. These are important to assess regional and global change. This portal could be utilised as the central clearing house for in situ observations of terrestrial ECVs. TEMS has been developed in collaboration with the Global Observing Systems Information Centre (GOSIC), which by itself provides access to data and metadata from GCOS and GTOS networks and systems. Action T40 [IP-04 T36] Action: Revision of TEMS with improved focus on the monitoring of terrestrial ECVs. Who: Parties’ national services and research programmes contributing to TEMS, in cooperation with GTOS, GOSIC, and the Global Change Master Directory (GCMD), and in consultation with the GCOS Secretariat. Time-Frame: By 2012. Performance Indicator: Improvement of site coverage measuring terrestrial ECVs. Annual Cost Implications: 1-10M US$ (Mainly by Annex-I Parties). 99 Covers mostly ground-based networks, as the datasets from satellite instruments are normally managed by the responsible space agencies. 100 Only recently established and not yet fully functional. 101 Stronger institutional linkage of this coordination body is required. 130
Implementation Plan for the Global Observing System for Climate in Support of the UNFCCC (2010 Update) 6.4. Terrestrial Domain – Scientific and Technological Challenges Some current and emerging ECVs call for concerted collaborative research efforts to bring them to the status of operationally-monitored ECVs within the Global Climate Observing System. The key priorities are: • Development and deployment of airborne and spaceborne microwave and lidar systems for measurement of above-ground biomass; • Addressing the cross-cutting challenge of sea level, i.e., assessment of ice loss from ice sheets, ice velocity, isostatic rebound, thermal expansion, and sea ice; • Monitoring biodiversity; • Assessment of extremes in the terrestrial domain; • Development of active (lidar) and passive sensors for the estimation of column CO 2 through satellites (cf. section 4.6); • Development of carbon data assimilation schemes, integrating observations from satellites, flasks, flux stations, and soil and forest inventories; • Untertaking Integrated Earth System Analysis, for consistent retrieval of ECVs through assimilation and reanalysis; and • Development of pilot soil moisture products from in situ and satellite measurements, and models. 131
