NIDS Radar Map Selector

NIDS (NEXRAD Information Dissemination Service) data consist of a variety of high resolution radar products from WSR-88D doppler radars. Data are updated frequently (about every six minutes).


Choose station, select type NIDS product, observation date/time, image size, single image or 2-hour GIF, Flash, or JSANI loop, zoom and image center location/zoom factor. This center location can be specified by using either a 3-letter radar identifier, an ICAO identifier, a WMO number (invalid entries will be centered on the station), or latitude,longitude (e.g. "ENX" or "KALB" or "72518" or "42.75,-73.80"). You can retrieve products back to about 15 days. If you don't set a date/time, center location/zoom factor, you will get the latest observation centered on the radar site with default zoom factor. The zoom factor only works when a center location has been set.

  • Some products may not be available for the selected station.
  • For loops, the date/time selected will be the approximate end time of the ~2 hour loop.
  • Blue lines on the maps depict interstate highways.
  • The "clickable" map options have less time resolution on loops, no capability to change size or center point of the image and no ability to go back to see data anytime over the past several weeks, i.e. less overall flexibility than from the option above.
