SMOS Funding Opportunity:Call for Proposals • Grid Processing-on-Demand (G-POD) for processing SMOS data • The Grid Processing-on-Demand (G-POD) environment [http://gpod.eo.esa.int] is a tool for EO data users offered by ESA for conducting Earth Science research activities. • G-POD is open to SMOS data users, who are again encouraged to submit proposals for: • The prototyping, development, validation, and operational deployments of new algorithms and “scientific added value products”, requiring high volumes of data and processing resources, • The development of new Earth science applications exploiting the synergetic use of EO data, including synergy with other space-borne and ground data, models and multidisciplinary applications. • G-POD SMOS proposals need to be submitted directly onto the following website: http://eopi.esa.int/G-POD. This is an open call, i.e. proposals can be submitted at any time.

  20. Ocean Remote Sensing (ORS) Proposal (pending)PI: STAR, Co-I: NODC, CPC • FY2013 Research Objectives and Tasks • Observations • Aquarius • Develop experimental quality-filtered Aquarius Level-2 SSS data stream for data assimilation • Routinely produce developmental NOAA-gridded Aquarius Level-3 products for specific applications and disseminate via NOAA OceanWatch • SMOS • Develop experimental quality-filtered SMOS Level-2 SSS data stream for data assimilation • Routinely produce developmental NOAA SMOS Level-3 products for specific applications and disseminate via NOAA OceanWatch • Ocean Color Radiometry • Compare ocean color radiometry (OCR) models to empirically estimated estuarine SSS • Generate error estimates of OCR-derived SSS in the Chesapeake Bay from the ANN and GAM models • Initiate SSS quality-monitoring framework • Climatology • Routinely produce developmental blended analysis of surface salinity (BASS) products in conjunction with NWS/CPC • Modeling • Investigate the SSS dependencies of operationally-significant passive microwave retrievals. • Initiate SSS data assimilation research and development for global HYCOM

  21. NASA 2012 ROSES Physical Oceanography (pending) On Assimilating Remotely-Sensed Sea-Surface Salinity in Ocean Models to (a) Improve Ocean State Estimates, and (b) Identify Errors in Surface Buoyancy Fluxes PI: EMC, Co-I: CPC, STAR • Addresses: • NWS operational SSS data assimilation: • Global Ocean Data Assimilation System (GODAS) • Real-Time Ocean Forecast System (RTOFS) • Surface buoyancy fluxes and salt budget analysis GODAS currently assimilates: a SSS climatology, Argo and CTD salinity profiles. A clear understanding of the SSS observations’ error characteristics required before attempting to assimilate the SSS observations. PLOTS: Scatter plots of monthly L3 salinity products (SMOS, Aquarius vs Argo); averaged over the top 20 meters and averaged into the same grid of 5o by 10o boxes. The Aquarius SSS fields have a strong positive bias in the Southern Ocean. Both SMOS and Aquarius SSS fields have a negative bias in the NE Tropical Pacific, although the bias is stronger for Aquarius. These kinds of issues need to be resolved and/or understood before these observations can be assimilated.

  22. NASA 2012 ROSES – Physical Oceanography (pending)Development and Application of Satellite and In-situ Blended Global Sea-Surface Salinity AnalysesPI: CPC, Co-I: NODC, STAR, JPL Components: • Develop a technique to construct global SSS analyses with uncertainty estimation through integrating (blending) information from in situ and satellite platforms, covering the global ocean at a 1° lat/lng grid for time resolutions of monthly or shorter. • Construct a processing system to generate the blended SSS analysis on a real-time basis to improve global ocean monitoring. • Examine the spatial distribution and temporal variation patterns of SSS and the interactions with air-sea fluxes, oceanic mixed-layer processes, and oceanic circulations. • Explore the possibility of improving the seasonal climate prediction using the SSS analyses developed.
