The NEXRAD radar I pull off www.nws.noaa.gov vary from 5 to 15 minutes,
depending upon the site.
I wonder why a television station would be concerned about that delay?
As others noted, sometimes a few minutes delay can make a
life-or-death difference. But I think stations want their own radar
for much the same reason they want their own meteorologists reporting
the weather. I remember when a station's weatherman was just a guy
who read the NOAA forecast, often dressed in a uniform advertising
Texaco or whatever company sponsored that segment. Then one station
hired a meteorologist (who emphasized, "MY forecast is . . .") and
suddenly they alll had to have one.
One station in my area ran ads promoting their Doppler radar showing
people carrying models of the radar tower around with them at work, on
picnics, etc. The tag line was something like, "We bought Doppler
radar so you don't have to."
Another station put a continuous feed of their radar on a digital
subchannel; local cable also carries it. But due to unexpected
consequences of ill-conceived FCC regs, they've decided to keep the
OTA viewers from seeing it. It's still broadcast so that cable can
get it (cable gets a direct feed of the same signal sent to the
transmitter) but it's marked "hidden" in the digital bitstream. My
computer-based tuners can still get it because they already knew how.
If I do a rescan I'll lose it.
That radar is quite handy and seems to be real-time. I check it
before going for a walk, and I work with satellite equipment that's
affected by rain, so it's good to know when we'll get hit and when it
will let up.
