Update on WSR-88D Level II Build 10 Changes 11 April 2008 NEW UPDATE AS OF 4/11/08:Change in Level II Data Format from KVWX. Build 10 was loaded on the Evansville, IN (KVWX) radar on 8 April. We had anticipated the Level II data available via NWS Level II Data Collection and Distribution Network would remain in MSG1 format and the software change would be transparent to users. However, once installed we learned the data can be sent with MSG1 or MSG31 format – MSG31 being the default.
We are sorry for this unannounced change. But with the data now being transmitted in MSG31 format we plan to leave the VWX Level II data in the MSG31 format. In the long run this should be a benefit to real-time Level II users to only have to maintain one decoder when Build 10 is loaded on the rest of the WSR-88Ds.
We will update the Build 10 Level II Interface Control Document to reflect only using the MSG31 format.
In Build 10, the LDM version identifier for KVWX will remain at Version 1. However, LDM Version 1 now refers to MSG31 radials in legacy data resolution at KVWX. Version 1 and Version 2 will be identical in terms of radial format and data resolution.
