## What is the 4-D Weather Cube?

**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?

**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?

**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 Observations/Diagnostics

**IOC Observations/Diagnostics**

- Radar
- Other Ground-based Observations
- Airborne Observations
- Space-based Observations
- Model Diagnostics/Analyses

## IOC IT Definition

**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

**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**

## FY09 Tasking:  IT Services
