Animation is one of the best ways for forecasters to observe the motion, growth, and decay
of radar echoes. In real time applications, many IRIS users leave a loop running constantly.
The Animation tool lets you control the animation sequence.
You can also use the Slide Show tool to automate the display of dierent products from
dierent times.
See Slide Show Tool (page 227).
Loop Start and Stop
Use these buttons to play (reverse and forward play) and stop animations. They are also
available in the Legend.
To use the SPACE BAR to stop a loop or start it in the forward play direction, place the
cursor in the image area of the loop.
When a loop starts, the Site filter automatically matches the loop so that only images from
the site (for which the loop was started) are displayed.
Loop Loading and Status
When a loop loads, it shows how many frames have been loaded and how many total frames
are available (29/30 in the example). The loop starts playing immediately, while it loads. You
do not have to wait for the loop to be fully loaded before it is playing at loop speed.
After the loading is complete, a number, 30 in the example, indicates the number of frames
in the loop. The time span shown is the actual span of the frames in the loop, not the
requested Max Time.
Factors that determine the number of frames in a loop include:
