SUBJECT:   CHANGE WSR-88D CLUTTER FILTER CONTROL PRODUCT AWIPS 
           CATEGORY NAME: EFFECTIVE OCT 27 2009 

REFERENCE: DATA MGT MESSAGE 08-09.01 / CENTRAL COLLECTION AND 
           DISTRIBUTION OF WSR-88D CFC PRODUCTS

STARTING OCTOBER 27 2009...THE AWIPS CATEGORY NAME OF THE WEATHER 
SURVEILLANCE RADAR 1988 DOPPLER /WSR-88D/ CLUTTER FILTER CONTROL 
PRODUCT /CFC/ / PRODUCT NUMBER 34/ WILL BEGIN TO CHANGE FROM NCF 
TO NC1 NC2 NC3 NC4 NC5. THE NUMBERS 1 THROUGH 5 WILL REFLECT  
SEGMENT 1 THROUGH 5. ON THE CENTRAL SERVER FTP SITE... INSTEAD OF 
DS.34CFC... THE PRODUCTS WILL BE STORED IN FTP DIRECTORY NAMES: 
DS.34CF1... DS.34CF2... DS.34CF3... DS34CF4 AND DS.34CF5.  

THE CHANGE IS NECESSARY BECAUSE THE USE OF NCF AS A NAME FOR ALL 
5 SEGMENTS CAUSES THE PRODUCTS FROM SEGMENTS 1 - 4 TO BE OVER 
WRITTEN IN THE NATIONAL CLIMATIC DATA CENTER ARCHIVES. THIS 
CHANGE WILL NOT IMPACT THE BANDWIDTH FOR REAL TIME USERS AND WILL
IMPROVE THE ABILITY OF WSR-88D DATA USERS TO BETTER UNDERSTAND 
THE CLUTTER SUPPRESSION APPLIED TO THE DATA.  

EXAMPLE OF NEW DATA PRODUCT APPEARANCE FOR THE KTLX WSR-88D:

AWIPS ID      WMO HEADER
NC1TLX        SDUS64KOUN
NC2TLX        SDUS64KOUN
