  1. NextGen Environmental Information Team: NextGen 4-D Weather Cube and IOC Requirements November 18, 2008 Cecilia Miner NWS Aviation Services Branch

  2. Overview • What is the Environmental Information Team? • What is the 4-D Cube? • What is the Single Authoritative Source? • What are IOC requirements? • What are FY09 tasks toward IOC?

  4. What is the 4-D Weather Cube? • The 4-Dimensional (4-D) Weather (Wx) Cube (3 dimensions plus time) will contain: • Continuously updated weather observations (surface to low earth orbit, including space weather and ocean parameters) • High resolution (space and time) analysis and forecast information (conventional weather parameters from numerical models) • Aviation impact parameters • Turbulence • Icing • Convection • Ceiling and visibility • Wake vortex • The 4-D Wx Cube of the future will contain “all” weather data, not just aviation parameters.

  5. What is the 4-D WeatherSingle Authoritative Source? • The 4-D Wx Single Authoritative Source (SAS): • Is only a portion of the 4-D Wx Cube • Provides a common weather picture for National Air Space (NAS) participants (Airlines, DoD, FAA, etc.) • Is the basis for all aviation decisions by Air Traffic Management (ATM) in the FAA • Is formed by merger of model data, automated gridded algorithms, climatology and observational data, and meteorologist input/data manipulation to ensure consistency and accuracy

  8. What are IOC Requirements? • Threshold - Minimum set of weather information required to meet anticipated automated decision support tools at IOC plus information required to meet FAA regulatory requirements • Objective – Additional data that may enable NextGen operations but which is not yet mature in development or which is not required by FAA at IOC

  9. IOC Observations/Diagnostics • Radar • Other Ground-based Observations • Airborne Observations • Space-based Observations • Model Diagnostics/Analyses

  10. IOC Forecast

  11. IOC IT Definition • Threshold – • Ability to exchange data between systems • Respond to requests • Support publish and subscribe • Objective • Support complex retrievals and calculations • IOC IT Concept of operations and architecture being defined in FY09

  12. FY09 Tasking: Cube Contents • Assess role of forecaster in the production of rapidly updated automated guidance for convection, turbulence, icing and low ceiling & visibility • Expand NWS gridded data sets • Conduct feasibility study of adding C&V to NDFD/NDGD • Demonstrate tools which allow meteorologists to add value to 4D automatically generated gridded information • Develop gridded LAMP output • Net-enable selected data sources for information sharing prototype

  13. FY09 Tasking: IT Services • Extend 4-D cube IT ConOps (use cases) • Develop integrated IT architecture • Investigate common IT security requirements • Conduct data exchange format gap analysis • Develop registry standards • Prototype interagency information sharing using federated registry standards • Begin IT service demonstrations • Examine NextGen test-bed integration options
