Continuously updating radar

[wawayanda]

I remember the local news mets (Bob Ryan in DC) used to show a "real-time" radar view that had a line sweeping around a circle with the radar image updating as the line passed. How was that different from what we see on radar views today? Whatever happened to that kind of radar and why is that style of "streaming" radar not available on GRLevel3 or the various apps and websites which update the full image at discreet intervals? IS that old style of radar updating available and if so, where?

 

Thanks!

I don't know, but if I had to guess my guess would be that that is their own in-house radar, and they can make it do that and think it looks cool... and sort of retro, I suppose.  I use GRL3 and it always has the latest data available and also updates automatically.  I know it is the latest data because I use it for stormchasing and I'm standing RIGHT THERE half the time.
