Many of the same commands used to display satellite images can be used with NEXRAD data as well. In this excercise, you will access real-time NEXRAD imagery, find a NEXRAD station where precipitation exists (if any) and list and display that NEXRAD station's radar image.
The DSINFO and IMGLIST commands list information about the available images. Once located, you can display the images using the IMGDISP command. You can display images one at a time or in a sequence. An entire set of images can be loaded chronologically using one IMGDISP command.
