Update on WSR-88D Level II Build 10 Changes
29 February 2008
NEW UPDATES AS OF 2/29/08:
1. Build 10 Beta Test at Paducah, KY Date Change. The Build 10 Beta Test
scheduled for next week at Paducah, KY has been delayed to the week of
10 March due to the likelihood of severe weather in the area next week.
The remainder of the Beta Test schedule remains unchanged. The plan now
is to load Build 10 software on the Paducah, KY (KPAH) WSR-88D on 11
March, weather and operations permitting. Need for delays due to weather
or other factors could lead to an installation date later that week.
Watch for Free Text Messages issued by the site
(http://weather.noaa.gov/monitor/radar/). When the radar is brought back
up on Build 10, the Radar Operations Center Beta Test team plans to
operate the radar using Recombined data through the next morning. Then
after the radar is taken off line the next morning to execute some
tests, the radar will be brought back on line (around noon) and be
transmitting Super Resolution data.
Paducah, KY WSR-88D - March 11
Yuma, AZ WSR-88D - March 18
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. The version of the Build 10 software that will go to Beta test will
be available on the National Weather Service Common Operations and
Development Environment (CODE) web site
(http://www.weather.gov/code88d/) on 3 March.
3. VCP121 will not change format in Build 10, but its performance in
reducing range folded data will be increased. The new VCP121 implements
the Sachidananda – Zrnic Algorithm (SZ-2) processing and Multi-Pulse
Repetition Frequency Dealiasing Algorithm (MPDA) to mitigate
range/velocity aliasing (the Doppler Dilemma). More details are
available in: Zittel et al, 2008: Combined WSR-88D technique to reduce
range aliasing using phase coding and multiple Doppler scans. 24th Conf.
on Interactive Information and Processing Systems (IIPS) for
Meteorology, Oceanography, and Hydrology, New Orleans, LA. Paper P2.9.
