NWS Next Generation Air Transportation System (NextGen)

4-D Data Cube

4 D CubeThe NOAA NextGen Weather 4-D Cube (aka the 4-D Data Cube) 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 necessary for Initial Operational Capability (IOC), include:
    1. Turbulence
    2. Icing
    3. Convection
    4. Ceiling and visibility
    5. Winds (surface and aloft)

 The 4-D Data Cube will contain “all” weather data, not just aviation parameters.

Broader Benefits to NOAA

collage of flight scenesThe NOAA NextGen Weather 4-D Data Cube will benefit NOAA and the NWS beyond aviation.

Aviation driven consistency and accuracy requirements will improve all NWS services as a result of the following:

  • Consistency challenges are not unique to aviation
  • More accurate public forecasts because of aviation driven high resolution modeling requirements
  • Improved severe weather lead times because of aviation driven convective forecasts possibly due to the implementation of “Warn on Forecast” technologies
  • Improved access to all NWS products and services via the 4-D Data Cube
  • Supports automated decision assistance tools for other agencies and entities
  • IT and Data Management will be enhanced
  • A central repository will be established to access critical NWS products and services
  • Also, will extend the AWIPS enterprise services into a ‘system of systems’ linking AWIPS, MADIS, NDFD, GOES, NEXRAD, and more...
