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.

What is the 4-D Weather
Single 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

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

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

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
12
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
