Update on WSR-88D Level II Build 10 Changes
12 March 2008
NEW UPDATES AS OF 3/12/08:
1. Build 10 Beta Test at Paducah, KY. Build 10 was successfully loaded
on the Paducah, KY (KPAH) WSR-88D on 11 March. Transmission of Super
Resolution Level II data began around noon on 12 March. The remainder of
the Beta Test schedule (below) remains unchanged, though delays in
installing the software due to weather or other factors could lead to an
installation date later in the designated week. Watch for Free Text
Messages issued by the sites when Build 10 is loaded:
(http://weather.noaa.gov/monitor/radar/).
Paducah, KY WSR-88D - INSTALLED
Yuma, AZ WSR-88D - March 18 (Super Resolution likely not available until
4 April when required bandwidth scheduled for installation)
South Kauai, HI WSR-88D - March 19 (no Level II available)
Edwards AFB, CA WSR-88D - March 25 (no Level II available)
Minneapolis, MN WSR-88D - April 1
2. A question has been asked why reflectivity data are being sent from
all Surveillance scan in the “Split Cuts.” Please see the following
information:
In WSR-88D Super Resolution Level II data, reflectivity data will be
transmitted during both the Doppler and Surveillance scans on "Split
Cuts" - where more than two scans are made at a given elevation angle.
In the Surveillance scan, only reflectivity data will be sent. In the
Doppler scan, data from all three moments will be sent. The RPG
Recombination Algorithm requires the second cut of reflectivity data.
Our recommendation is for users to use the reflectivity data from the
first scan (Surveillance). The first scan of reflectivity data is
collected using a long PRT so that the data is range unambiguous. The
data range is 460 km and will be either 1 km resolution (if Recombined
data) or 0.25 km if Super Resolution data.
The second scan of reflectivity is collected using a short PRT and
therefore the data requires range unfolding in the RDA. Furthermore, the
reflectivity data on the second scan has a maximum range of 230 km, the
same as the Doppler information. This data will be 0.25 km resolution,
same as the Doppler data.
3. The version of the Build 10 software being used in the Beta Test is
available on the National Weather Service Common Operations and
Development Environment (CODE) web site (http://www.weather.gov/code88d/).
