In situ• provide a comprehensive
observation basis regarding the land surface
• deliver long-term datasets to monitor trends and detect environmental changes in key terrestrial variables;
• provide crucial verifiable data for calibration and validation of satellite products;
• provide data to be integrated or assimilated within forecasting or analysis models;
• Provide regionalized and local data for use in downstream services.
•But, often run in research mode, no sustained funding, limited data access•Data are being collected for non-climate purpose and have economic value (water, wood)
GTN-R
There is concern at the lack of progress in GTN-H to get more river discharge stations on board
GTN-Permafrost, Glaciers do wellLargely because there is dedicated institute (CALM).
Aletsch use of Aster/GISData WGMC
EU: GMES Recommendations for In situ• The GMES global land group proposes to select a
number of networks for participation in a fast track in situ effort.
• Maturity of the network (state of harmonization/standardization, availability protocols, data quality control and data access)
• Relevance to global networks (e.g. the network forms part of a global network, e.g. GTN-G, GTN-H, FLUXNET, etc)
• Critical to understanding of changes in System Earth (GTN-P, LifeWatch, ICOS)
• Critical to providing local scale data and calibration/validation data for the space component of Global Land services
• Initially concentrate on coordination support activities
• While we have a number of satellite ECV products, like albedo, Fapar etc., their validation is generally poor
• We need to find a
mechanism to get our set of 35 global reference sites (linked with Fluxnet) and CEOS Cal-Val, similar to GRUAN
