All you people with links to "live radar sites" have your work cut out for you on 1/1/2001! That's all I can say for now, but trust me, you're gonna love it.

I too am excited about the possibilities with the termination of the NIDS agreement however I think it is important not to become too optimistic. The NWS will initially not be offering any animation or mosaics. It really isn't too practical for the average home computer user to be trying to FTP megabytes of radar data every few minutes, then decompressing the files and trying to view them in whatever format (I'm not so sure it will be GIF's) the NWS uses. Finally, look at the reliability of the NWS communication circuits and computer systems. There isn't a day that something isn't broke. I think I'll keep my Kavouras and WeatherTap just a little longer. Steve -- Steve M.

No, there will be GIFs available too, that is for sure! Mosaics, no. Animations, I don't know.

Well, if the NWS breaks after January 1, they take Kavouras and everyone else with them. That's because they will unplug from the radar sites directly, and solely fly with the NWS feed. ******************************************************************************* Gilbert Sebenste ******** Internet: address@hidden (My opinions only!) ****** Staff Meteorologist, Northern Illinois University **** E-mail: address@hidden *** web: http://weather.admin.niu.edu ** Work phone: 815-753-5492 * ******************************************************************************* ------------------------------ Date: Mon, 6 Nov 2000 19:18:36 -0600 From: Gilbert Sebenste <address@hidden> Subject: More radar news... I just learned that there will be Javascript animations of the radar products on the web sites! So, there ya go. Of course, you'll still need a radar vendor for mosaics, but with Accu-Weather giving them away in real-time now (with others that may follow), I think we'll see real-time stuff on all the sites, with banner ads. I wonder what WSI, Accu-Weather and the others will do? Suspicion: make the NIDS stuff free and banner ad those mothers like crazy for profit. Something's going to have to give... ******************************************************************************* Gilbert Sebenste ******** Internet: address@hidden (My opinions only!) ****** Staff Meteorologist, Northern Illinois University **** E-mail: address@hidden *** web: http://weather.admin.niu.edu ** Work phone: 815-753-5492 * ******************************************************************************* ------------------------------ End of WX-TALK Digest - 5 Nov 2000 to 6 Nov 2000 (#2000-286) ************************************************************ ---------- End Forwarded Message ---------- Linda Miller - address@hidden External Liaison, Unidata University Corporation for Atmospheric Research P.O.
