Help with Satellite Loop

Option Menu

  • About IR Satellite Images - this item takes you to a page that describes how to interpret the images in the loop.
  • Set End Time - this option will put up a widget that lets you set the end time for the loop. The only dates shown are ones for which data is available.
  • Clear End Time - this option removes the End Time widget and resets the end time to the current time (which is the default). In this mode the loop will check for new images every 5 minutes and update the loop if necessary.
  • Save Settings - this option will save the current speed and loop length in a HTTP cookie. These will become your defaults whenever you go to the radar loop page. Note that cookies are usually stored on your computer by the browser in its own area. Thus if you go to another computer, or another browser on the same computer, the cookie (and thus the defaults) may be different.
  • Clear Settings - this option will clear the saved settings by deleting the cookie set by the "Save Settings" option.
  • Show URL - this option will pop up a window showing a URL you can use to go back to the exact same loop that is running at that time you choose this option. See discussion on "URL format" below for more details.

URL format


Arguments can be added onto the end of the URL for radar loop page that will set up initial values for the settings. To specify arguments, just add a "?" at the end of the URL and separate the arguments with a "&", for example:

The available arguments are:

  • speed=n - speed in frames/sec from 1 to 20.
  • length=n - loop length in hours from 1 to 8.
  • end=date - end time of loop formated as "dmmmyyyy;hh:mm". For example "6Nov2010;14:00". The time is for the Pacific time zone.
