Title	Sensor-Analysis-Model Interoperability Technology Suite

This proposal addresses NASA's requirements for enabling model interactions in sensor webs using service oriented architecture principles and geospatial interoperability standards. Sensor webs provide a new type of dynamic and real-time resource for earth science data analysis and modeling. The future interaction between sensors and models is expected to be bi-directional: sensors provide input data to models; model output provides information for planning where, when and what sensors will measure next. Today's earth science models are not capable of routinely assimilating sensor web observations and less capable of driving sensor measurements. The proposed project will use and extend geospatial interoperability and emerging sensor web standards, such as the Open Geospatial Consortium Sensor Web Enablement specifications, to bridge the gap between sensors and models. The proposed project will develop a Sensor-Analysis-Model Interoperability Technology Suite (SAMITS) that provides a package of standards, technologies, methods, use cases, and guidance for implementing networked interaction between sensor webs and models. SAMITS will foster seamless two-way data and control flow between active sensors and data analysis/modeling tools. SAMITS will be tested through use case applications that tie together atmospheric, air quality, and fire sensors with weather and smoke forecasting models. A tenant of the proposed approach is to reuse and extend existing technologies and development efforts. NASA's return on investment will be maximized and the time to implement two-way interaction between sensors and models minimized if the new technology development reuses existing distributed and interoperable information system components that are already available to assist in information flow between observation databases and models. Technology Readiness Level (TRL): Entry=2/3; Exit=6 Period of performance: 36 months.
