If you keep getting 0 UTC analyses by accident...

Latest version is 7-Oct-2009: the extended range option now goes up to 0.5 mb, rather than 10 mb. See change details (in another window) for more information. (To get the new code, you may have to restart Internet Explorer, or for Firefox/Mozilla/Netscape, hold down the shift key and click reload.)

The new URL for non-java soundings is http://rucsoundings.noaa.gov/gifs/

    (If the display does not work for you, you can still access the old version for a while, but let me (Bill.Moninger@noaa.gov) know so I can fix the problem.)
