This paper describes the scope, objectives, schedule and activities necessary to build the 4-D Weather Data Cube. The 4-D Weather Data Cube is a multi-agency Federal- Industry partnership that will build a virtual 4-D weather data base containing the necessary information to support aviation decision making. This paper also highlights the Single Authoritative Source, a subset of the 4-D Weather Data Cube that will be used for all “official” ATM decisions. Much of the near term work is centered on delivering an Initial Operating Capability in 2013.
Building and populating the 4-D Weather Data Cube will be a challenging activity that will extend through the year 2022. Many of the requirements for environmental data exceed the current state of the science and will require robust research and transition to operations phases to fully realize the promise of NextGen.
