Dataset: NEXRAD level 3 Radar (NIDS)

• Data format: NIDS
• Data type: Radial
• Collection type: TimeSeries
• Harvest: true
• Naming Authority: edu.ucar.unidata
• ID: NWS/NEXRAD3

Documentation:

• summary: The NIDS data feed provides roughly 20 radar products sent every 5-10 minutes from 154 sites over NOAAPORT broadcast. These "derived" products include base reflectivity and velocity, composite reflectivity, precipitation estimates, echo tops and VAD winds
