NextGen Network Enabled Weather (NNEW) is part of an interagency effort to provide quick, easy, cost-effective access to weather information for all weather users. NNEW will define and provide the FAA’s portion of the 4-Dimensional Weather Data Cube (4-D Wx Data Cube), an infrastructure that will enable common, universal access to aviation weather data. Through the Cube, users will have improved access to timely and accurate weather information, supporting improved decision-making and enhancing safety.

The 4-D Wx Data Cube consists of (1) weather data published in various databases within the FAA, National Oceanic and Atmospheric Administration (NOAA), and Department of Defense (DoD), as well as commercial weather data providers that may participate; (2) registries/repositories needed to locate and retrieve published data; (3) the capability to translate between the various standards that will be employed to provide data in user-required units and coordinate systems; and (4) the capability to support retrieval requests for data volumes (e.g., the area along a flight trajectory). A subset of the data published to the Cube will be designated the Single Authoritative Source (SAS). The SAS will identify the preferred data source that should be used to support collaborative air traffic management decisions and ensure that decisions are based on consistent data.

Although NNEW will provide basic reference software to its users as examples of how software clients can make use of the 4-D Wx Data Cube, it will not develop a definitive user interface for accessing and parsing the Cube's data. Rather, the Cube will output information in standardized file formats, and NNEW will provide documentation with the information necessary to create custom software that adheres to those standards.

The NNEW Wiki provides documentation and software related to the program planning and prototyping phase of NNEW. The contents of this site do not constitute final implementation or design for the FAA NNEW program. If you are new to NNEW, please visit the Introduction to NNEW page for an in-depth description of the Program and its goals.
