  1. Development of a Global In-Situ Soil Moisture Network:A SMOS Project Contribution P.J. van Oevelen SMOS SAG, Villafranca November 2-3, 2006

  2. Outline • Previous: Rationale, Framework • Current: Roadmap, Statement of Work • Future: Timeline, Required Contribution SMOS SAG, Villafranca November 2-3, 2006

  3. Previous SMOS SAG, Villafranca November 2-3, 2006

  4. Rationale • No current global network • Soil Moisture regarded as (emerging) key variable • Temporal change is more important than spatial representation • Data Assimilation • Earth Observation Validation/calibration • EO does not give profile information SMOS SMOS SAG, Villafranca November 2-3, 2006

  5. Measurement Protocol • Uniformity • Representative • Consistency • Cross-Calibration/Validation • Relationship with gravimetric soil moisture / standard of reference? • Careful automation • Quality Assurance • Density/depth/number of sensors • Enable unified instructions on installation and measurement procedure • Discontinuity in series easier to take into account • Full range of possible soil moisture values • Important because time series are of essence • (limited number of stations) SMOS SAG, Villafranca November 2-3, 2006

  6. Operational • Continuity • Timely delivery –NRT? • Automation • Linked to Operation Forecast Centres SMOS SAG, Villafranca November 2-3, 2006

  7. Current SMOS SAG, Villafranca November 2-3, 2006

  8. SMOS Project Soil Moisture Database • Who will host? • What should be in it? • What type of interface? • Future links/continuity? SMOS SAG, Villafranca November 2-3, 2006

  9. Who will host? • Proposed: Portuguese Meteorological Institute in Lisbon, Portugal • Point of Contact: Pedro Viterbo • Why? • Current host EUMETSAT LandSAF: http://landsaf.meteo.pt/ • Capability and capacity • Timeliness / administrative advantages • Continuity • Willingness to adhere to (CEOP) standards • Flexibility – direct link to operational services NRT! http://www.meteo.pt/en/previsao/inicial.jsp SMOS SAG, Villafranca November 2-3, 2006

  10. SAFs (Satelite Application Facility) currently use data from both meteorological satellites in geostationary orbit as well as from polar-orbiting satellites. There are currently 5 SAFs in the initial operations phase: • Support to Nowcasting and Very Short Range Forecasting • Ocean and Sea Ice • Climate Monitoring • Numerical Weather Prediction • Land Surface Analysis And a further three under development: • Ozone Monitoring • GRAS Meteorology • Support of Operational Hydrology and Water Management The SAFs help deliver a variety of benefits including: • Improvements to short-range forecasting of severe weather hazards • Support to the aviation, agriculture, construction, gas, water and electricity industries • Better understanding of the causes and effects of pollution of the upper atmosphere and the depletion of ozone • Early warning of hazards • Better data for climate monitoring • Improved information for land use, ecology, disaster monitoring and agricultural forecasting • Benefits for sea transport, fishing and offshore industries • Improved data for input to Numerical Weather Prediction and the availability of user software packages for operational applications • Improved software packages and near-real time and offline products SMOS SAG, Villafranca November 2-3, 2006

  11. What should be in it? • In-Situ Soil Moisture Data • Including metadata • Extensive site description • (EO) Data from SMOS CAL-VAL • Any data relevant to SMOS CAL-VAL • Data archive • Clear data policy description / access control • Data control / consistency check SMOS SAG, Villafranca November 2-3, 2006

  12. What type of interface? • Web based plus ftp • Open structure / access (related to policy) • Upload / download • ISO 19115 standardized (metadata) • CEOP compatible / shadow hosting? SMOS SAG, Villafranca November 2-3, 2006

  13. Future links / continuity • Database beyond SMOS CAL/VAL • Direct link to GEO(SS) – CEOP Prototype • EO Portals (ESA, GEO others) • Development from centralized to distributed archive • Assimilation into global observational networks (GMES, G3OS, GEOSS etc.) SMOS SAG, Villafranca November 2-3, 2006

  14. Coordinated Enhanced Observing Period http://www.ceop.net/ A Prototype of the Global Water Cycle Observation System of Systems SMOS SAG, Villafranca November 2-3, 2006

  15. Near Future: • Detailed and Final Statement of Work before end of this year (First draft ready now) • Data formats (up and download) • Needs from SMOS Cal-Val? • Allow for changes/flexibility in Database set-up! • Secure funding / continuity (2007 start) Relevant for period after SMOS Cal/Val SMOS SAG, Villafranca November 2-3, 2006

  16. THANK YOU SMOS SAG, Villafranca November 2-3, 2006

  17. Strong User Community • Involvement • Support • Interaction • Application Fields • Earth Observations • Weather Forecasting • Climate • Climate Modelling • Agriculture • Water Resources SMOS SAG, Villafranca November 2-3, 2006

  18. Global In-Situ Soil Moisture Network SMOS SAG, Villafranca November 2-3, 2006
