Definition
The U.S. Department of Commerce is the federal executive department that oversees the National Oceanic and Atmospheric Administration (NOAA), which in turn operates the National Weather Service (NWS). The NWS, together with the FAA and the Air Force, jointly operates the NEXRAD network of weather surveillance radars used for aviation weather products.
Plain English
The Department of Commerce is the part of the U.S. government that runs the national weather agencies. It is one of the three groups (along with the FAA and the Air Force) that operates the network of weather radars pilots rely on.
Context Anchor
Seen in FAA weather radar discussions when the handbook names the government agencies involved with the NEXRAD weather radar system.
Why Pilots Care
Weather products pilots rely on for safe flight planning come from agencies under this department.
Intuition Check
DOC does not mean a doctor or a document here. In this FAA weather context, it means the U.S. Department of Commerce.
Example Sentence 1
The NEXRAD network is jointly operated by the Department of Commerce, the FAA, and the U.S. Air Force.
