Presentation Transcript

  1. Measuring Land surface fluxes – Soil profiles – Hydrological balance Objectives • List possible contributions to WG2 • local measurements on specific ecosystems, • Mesoscale/pilot-sites -long term observatories • Define measurement requirements • Common (internal) database ? • Organisation of Task Team for Observation ?

  2. Local measurements on specific ecosystems Requirements • SOP (at least) – EOP recommended (L • Fluxes • Water (& Carbon), Energy • Footprint (wind direction) • Soil moisture/temperature (surface e.g. 5cm, deep e.g. 30cm) • Soil characteristics (water storage capacity, depth, texture) • Water table (where relevant) • Atmospheric forcings • Air temperature/humidity, SW, (LW) radiation, Wind speed, Precipitation • Vegetation description (type, height, LAI) When possible • Ecophysiological measurements (sap flow, water potential, stomatal resistance …) Synergies between sites : methodology

  3. Local measurements on specific ecosystems List of sites • CarboEurope (UNITUS?) • Observatories in SE France • Avignon –crops- • Tour du Valat –salt marshes • Crau –dry grasslands • Fontblanche –mixed forest (TbC) • Manosque, OHP - oak, France (TbC) • Puechabon CarboEurope site – oak, France (TbC) • Corsica (TbD), D. Lambert + KIT, INRA orchard site? Natural vegetation?, soil moist/temp, fluxes, 1 year

  4. Local measurements on specific ecosystems List of sites • Italy • Lecce –mixed periurban • Bari –crops • Lamezia Terme, Calabria (am.sempreviva@isac.cnr.itwww.crati.it) –orchards (TbC) • Tor Vergata –grass, turbulence, boundary layer, upgrade TbD • Lampedusa (alcide.disarra@enea.it) – dry grassland, radiation fluxes, heat flux, upgrade TbD

  5. Mesoscale/pilots -Sites Requirements • Improved estimation of the water balance on small sub-catchments • EO data • Land cover mapping • Vegetation dynamics Possible • Upscaling with airborne observations, e.g. both sea and land (KIT –Dornier-128, SAFIRE –ATR-42)? • Fluxes • Remote sensing (e.g. microwave radiometry, infrared, VIS/NIR) • Spatial variability at fine scale (Hillslope) of soil moisture Synergy between sites and WG3 : methodology sharing, intercalibration?

  6. Mesoscale/pilot-Sites List of Mesoscale/pilot sites • Remedhus, Spain, Salamanca • SMOSMANIA+OHMCV, France • Crau-Camargue (drylands, wetlands), France • Karst observatory, HSM (+BRGM), France • Emilia-Romania, Italy • Extensive soil moisture network in Turkey (TbC) • Israël, network of sites (TbC) • Croatia ? • Egypt? • North Africa?

  7. Upgrade and measurements implementation • To reach the site requirements (funding?) • Implementation  funds strategy  Build an exchange strategy to make HYMEX experiment attractive for experimentalist

  8. Common internal database? • Usefulness • visibility • easier data access within the project • « Meta-data+links » seems more realistic than a central database (Existing long-term sites with their own data policy, diversity of instrumentation for different sites) • TbC at project level

  9. Organisation of TTO? • A TTOs per mesoscale/pilot site + Coordination (TS?) • One TTO for all local sites • Per-variable TTOs don’t seem useful (standardization and intercalibration strategy to be done at the TS level) • A form will be sent in order to characterise the possible (super-) sites
