8. April 3, 20088 Sensor Web Meeting, Working Group Middleware II 8 Coastal Ocean Use Case Overview Name, POC: Coastal Ocean Modelling, Data Assimilation and Prediction, Payman Arabshahi Goal: To improve ocean modeling in coastal regions by making sustained measurements with increased accuracy and spatial/temporal resolution. Summary: Provide ocean and climate change scientists with improved climate change model outputs (ROMS outputs) by including integrated in-situ and space based sensor data, thus increasing accuracy and spatial/temporal resolution of model outputs. Highlights: future contributions to Earth science –JASON-1 - measures the ocean surface topography (current) –QuickSCAT - measures wind speed and direction information over oceans (current) Part of AIST demonstration –OSTM - measures sea surface height (future) –Aquarius - measures global sea surface salinity (future) Missions in NRC Decadal Survey in the 2013-2016 time frame –SWOT- Measures ocean, lake and river water levels - Ka band wide swath radar, C band radar –XOVWM - measures sea surface wind vectors for weather and ocean ecosystems Predictive Models Virtual Space Supercomputing Sensor Web System Space, In-Situ (Oceans ) Data Assimilation Adaptive Sampling

10. April 3, 200810 Sensor Web Meeting, Working Group Middleware II Plant Monitoring Use Case Overview Multimodal Plant Monitoring –POC: Wei Ye, Categorization: sensor management Goal: –Multimodal sensing of plants bloom in response to precipitation. Summary –Capture the dynamic response of plants to rainfalls Sap flow sensors, imaging sensor, weather station –Dynamically adjust sampling rates of sensors when relevant environmental events are detected Day time (regular rates) and night time (power down), detected precipitation (high rates) Highlights –Event-triggered reconfiguration of in-situ environmental sensors

12. April 3, 200812 Sensor Web Meeting, Working Group Middleware II Use Case Lessons Learned Identify “collective results” of looking at several use case –Communications system management –Sensor management –Work flow management Implications for next steps –The majority of the cases related to workflow management – this area appears to be offer more opportunity for development Suggestions on how to promote use cases –Use the “value chain” analysis (more science? Better science? Cheaper science?) –Emphasis on simplification through abstraction… –Use animation / DVD –Live demonstration Provide feedback to ESTO AIST team –The use case work should not wait another year – this should be an ongoing area of interest

13. April 3, 200813 Sensor Web Meeting, Working Group Middleware II New Sensor Web Features, Needs Identify new features or benefits –Inclusion of a broader discussion of interoperability List any new AIST needs

14. April 3, 200814 Sensor Web Meeting, Working Group Middleware II Recommendations Suggestions for ESTO next steps –Continue to refine use cases Closer look at decadal survey relevance –Perform value chain analysis –Perform mashups of cross cutting use cases Crosscutting PI teams Identify specific individuals for sensor web follow up How can AIST or info systems in general, influence planning for Decadal Survey missions –Bring John Garstka to the “big” meeting with the HQ mission managers
