• Notes
  1. Loop/Sweep/None toggle switches between a loop through the forecasts (nowcast-24 hr-48 hr-72 hr-96 hr-120 hr-140 hr) to sweep back and forth through the list of selected images (see navigator notes below on image selection).
  2. The Navigator control has three functions: (1) the green dots indicate images loaded and ready to display. The current image is shown as a blue dot in the control. (2) If an image is not available, the viewer will show a red dot at the corresponding position in the loop and will skip over it. (3) If you Control-Click (hold the Ctrl button while clicking) on a green button, it will toggle to red and the viewer will skip that image when you single step or loop it.
