-------- Original Message -------- 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 12. 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. 4. Level II users should periodically check "news" at: http://www.roc.noaa.gov/NWS_Level_2/BuildInfo/b10main.aspx.
