What does DDN mean in METEOROLOGY
The Defense Data Network, or DDN, is a computer network operated by the U.S. Department of Defense (DoD). It began operations in 1982 and was used to link DoD computers and other like systems around the world. This includes all services of the military as well as non-DoD agencies such as NASA. At its peak, it had more than five million users including both government and commercial customers. DDN is a part of the larger DoD information infrastructure known as the Global Information Grid (GIG) and has been replaced by newer networks such as the Network Centric Enterprise Services (NCES).
