OKX radar upgrading to dual-polarization

33 posts in this topic

The upgrade will begin on January 16th, 2012. The radar site is expected to be down for two weeks. "Dual-polarization helps the radar better distinguish what types of precipitation it scans, which will enhance the accuracy of our forecasts and warnings. All National Weather Service radars around the country will be upgraded with this technology over the next two years."

An interesting conversation is occurring on the GRLevelX forums about the initial usefulness of dual-pol in terms of actually determining type of precipitation.

Are there other decent radars (websites?) available as a substitute, which would include SW Conn as well?

You can use the Newark/JFK TDWR and the Boston, Albany, and Mount Holly radars to get decent idea as to what's transpiring.

maybe this would help the weathertap radar.... man, the precip types weren't even close for the October storm.. but I realize those were unusual circumstances... I like weathertap's radars, but using it for precip type generally doesn't work very well, in my experience.

Part of this has to do with the elevation of the radar beam. At the end of the day, nearby surface reports are going to be the best ground truth.

Unfortunately being about 15 miles NE of Bridgeport puts me at the outer limit of the other regular radars and out of the range of the TDWR's. They'll be O.K. for an idea like you say but they are usually not as accurate here.

Finally, something I know something about! :lol: I'm more than excited for this.

Unfortunately, the dual-pol data is primarily proprietary right now and won't be available on the NWS site (yet). Besides the GRLevelX plugin, the only way for most of us to view the dual-pol variables will be through the Radarscope App on our mobile devices.

Link? I don't know why it wouldn't immediately be useful...

Looks like I need to be a user there to read it. Oh well.

OKX posted a link the other day to details on the precipitation type analysis in dual pol...it was def. interesting to see how they analyzed the melting/etc to determine where the rain/snow boundary was.

Here's a link from the Chicago NWS about how they've used dual-pol in their recent winter storm. Some very clear examples (where there was not significant bright banding in the Z).

WEATHER AND NON WEATHER TARGETS. THIS UPGRADE WILL RESULT IN
IMPROVEMENTS TO THE NATIONAL WEATHER SERVICE RADAR PRODUCT SUITE
THAT WILL ENHANCE PROTECTION OF LIVES...PROPERTY AND THE ECONOMY
THROUGH IMPROVED WARNING OPERATIONS.
THIS MAJOR UPGRADE WAS ORIGINALLY SCHEDULED TO BEGIN ON THE NATIONAL

Looks like OKX is dual-polled! I just looked at weatherscope on my android and the Dual Pol products are available now.

Hydrometeor Classification.... Looks like its indicating clutter as you would expect.

good to know we have it though on our smart phones, i hate the mt holly radar for north of nyc

I think the regular radar data is back up. You wont be seeing dual pol on any NWS site for awhile, just from other venders who pay for the data.
