Choose station, select type NIDS product, observation date/time, image size, single image or 25 frame GIF or HAniS loops, 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 now works even if a center location has not 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 loop. Loops may take anywhere from 25-60 seconds to generate and display depending on server activity. During non-busy server periods, loops will usually contain 25 images. However, the number of images may be reduced during busy server periods, but these abbreviated loops will contain the closest images to the end time selected.
  • 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.
  • These NIDS Level III products are explained in the "Productn Description" section (pull down lists) in this NCDC webpage.
