  1. SWOT First Science Definition Team meeting Hydrology Splinter Session Conveners: Doug Alsdorf, Jean-Francois Cretaux, Nelly Mognard Discussion Item 4 : Interactions with other Hydrology Missions, Sensors, Modeling, and Data Assimilation Dennis Lettenmaier (University of Washington, U.S.) Ahmad Al Bitar (CESBIO, CNRS , France) SWOT - First Science Definition Team meeting - Pasadena, January 28-30, 2013

  2. Support for discussion 1 Enhancing SWOT retrievals by usinginfromationfromothersensors SWOT - Spatial resolution - Temporal resolution - Coverage - Accuracy Retrieval algorithms Enhanced SWOT products EOS 2 Enhancingourknowledge by combining SWOT withothersensors Models with or without Assimilation methods SWOT L4 – Combined products (added value) EOS

  3. Support for discussion 1 Enhancing SWOT retrievals Examples of potential ancillary datasets - Enhanced land cover (water mask, land cover, land overlay…) - using optical sensors Pleiades 1 2 – (CNES), LDCM (NASA), Sentinel 2 – A & B (ESA) - using radar and PolnSAR Sentinel 1 – A & B, RiSAT 2(ISRO) - Enhanced & dynamic DEM (topography overlay) -using radar for DTM TanDEM-X (DLR ), P-Band radar Biomass (P-Band) (ESA) -using optical for DSM Pleiades1 (tri-stereo) (CNES) (1.5m relative accuracy)

  4. Support for discussion 1 Enhancing SWOT retrievals Examples of potential ancillary datasets - Enhanced time coverage SWOT with other altimetry missions Jason 2 (CNES NASA), Jason 3 (CNES NASA), CryoSat (ESA), Altika (CNES ISRO)

  5. Support for discussion -

  6. 2 Enhancing our knowledge by combining SWOT Precipitation Discharge & lake storage SWOT Vegetation GPM Total storage LDCM Sentinel2 Soil moisture SMOS Discharge runoff SMAP Multi-sensor Assimilation into integrated Eco-Hydrological modeling unsaturated zone GRACE-FO illustration (irrelevant scale) Ground water

  7. - Build upon existing and contributing to community tools: Community Land surface models CLM, SURFEX integrate already hydrological models but not 2D hydraulic models. LDAS (Land Data Assimilation Sytems) - NASA NLDAS GLDAS ? - Meteo-France (Surfex-EnkF, Surfex-ExKF) ? - ECMWF (HTESSEL) An organization of the hydrology community is needed to find adapted solutions to go forward (Wood et al., 2011) and even understanding the processes (Beven & Clocke, 2012).

  8. Support for discussion What are the adapted assimilation algorithms for SWOT data ? How to take into consideration scale issues as sensors have very different resolutions (assimilate coarse into fine scale model) ? Can we deliver an enhanced discharge product trough assimilation ? By how much ? (Durand et al. 2010?) In the case of multi sensor approaches, what is the contribution of each sensor to the enhancements ? What are the drawbacks of using assimilation ? (interdependence, robustness, …

  9. 2 Enhancing our knowledge by combining SWOT with other sensors Examples of potential ancillary datasets - Water quality - Sediment transport using Optical sensors LDCM, Sentinel-2 A B, Pleiades1 Hydraulic model coupled to sediment transport model - Water temperature using thermal sensors LDCM, Mistigri ?? (CNES) Hydraulic model coupled to thermodynamic models
