Why are Four Live Doppler Radars Better Than One?

The TrueView Doppler 104 gives our viewers something they've never had before... Four live, state-of-the-art radars... each one, strong enough to punch through nearly any storm.

Meteorologist Chris Jarzynka says, "You're dealing with four National Weather Service, top of the line, Doppler radars, not just one that has been installed by someone at a television station. So, you're getting four times the coverage... You're getting four times the information, and you're getting that information up to the minute."

Up-to-the-minute reports from four, live radars... these radars have lots of power.

Meteorologist Greg Patrick says, "750 kilowatts at peak power."

And the TrueView Doppler 104 radars have a wider bandwidth than even the best television radar.

Meteorologist Harold Brooks says, "It's a ten centimeter Doppler radar, which means it can see through storms. It doesn't have as much attenuation problems as shorter wavelength radars have."

Harold Brooks is a research meteorologist at NOAA's National Severe Storms Laboratory in Norman, Oklahoma. He's concerned about attenuation... Attenuation is when the shear volume of rain or hail obstructs a radar's view of a storm.

Brooks explains, "If you're looking with a short wavelength radar, you may see a nearby storm, but if there's a second storm down the line from it, you may dramatically underestimate how much is coming out of that storm."

Jarzynka adds, "What if there was a tornado behind it?... or some sort of circulation behind it? their television radar can't penetrate that wall of hail, whereas the national weather service Doppler radars have more power or a different wavelength to actually see through that, to what's coming in behind it."

Jarzynka is a meteorologist who travels the country, training meteorologist on the TrueView system, which he says can even interpret the data faster than the National Weather Service.

Jarzynka explains, "We can actually get that information into the hands of your meteorologists about three or four minutes earlier sometimes than even the national weather service can do. And - as you know - in a tornado situation, three or four minutes can make the difference.

Patrick adds, "In that case, it's a good idea for us to be able to look at the surrounding radars to get a good view of what that storm's doing."

Greg Patrick is science officer for NOAA's National Weather Service office in Fort Worth, Texas. He advocates a network of radars like the one the national weather service has... And the one we have with the TrueView Doppler 104.

"If you get more than one view of something, you have a better idea of what's going on," adds Brooks. "So every time we can look from more than one place at a thunderstorm, we get a better three-dimensional picture of what's going on."

And this is just the core of the TrueView Doppler 104 system.

Jarzynka sums up, "The system that you are going to be seeing on the air is the exact same computer technology that's being used on the today show."

And there is so much more to the TrueView Doppler 104... like sky-view forecasting, eight weather-models each day, and much more.
