AS PART OF RWS BUILD 2 SOFTWARE UPGRADE SYSTEM TEST... NWS
WILL CONDUCT A DATA COMMUNICATIONS TEST IN DECEMBER 2009
AND JANUARY AND FEBRUARY 2010 USING TEST HEADERS.
IN ADDITION A PRELIMINARY TEST WILL BE CONDUCTED TO CHECK
OUT THE END TO END COMMUNICATION IN NOVEMBER 2009.
THIS TEST WILL ORIGINATE FROM THE NWS STERLING FIELD
SUPPORT CENTER /SFSC/. THE TEST WILL CONSIST OF DAILY UPPER
AIR CODED MESSAGES TRANSMITTED DURING THE NORMAL SYNOPTIC
WINDOW FOR THE 00Z AND 12Z SOUNDINGS... AND AS NECESSARY
... AT ASYNOPTIC TIMES WHEN WEATHER CONDITIONS AND TEST
REQUIREMENTS WARRANT. THESE TEST MESSAGES WILL BE IN THE
SAME FORMAT AS OPERATIONAL MESSAGES BUT WILL HAVE DIFFERENT
DATA REFLECTING UPPER AIR CONDITIONS AND CODING PRACTICES
AS EXPLAINED BELOW.
A TEST HEADER HAS BEEN ESTABLISHED FOR THE TEST: KSTA
/STATION ID 69990/ WAS ESTABLISHED FOR THE STERLING FIELD
SUPPORT CENTER /SFSC/. THE KSTA TEST CODED MESSAGE FORMAT
WILL BE IN THE RRS FORMAT NOW IN SERVICE AT OVER 60 UPPER
AIR SITES. RRS FORMATTED PRODUCTS ARE A RESULT OF CHANGES
MADE TO THE WORLD METEOROLOGICAL ORGANIZATION /WMO/ LEVEL
SELECTION CRITERIA AND UPDATED CODING PRACTICES. FOR
ADDITIONAL INFORMATION REGARDING THESE MESSAGES... PLEASE
REFERENCE THE MANUAL ON CODES WMO NO. 306... SECTION A.
WHEN THE INDIVIDUAL KSTA RRS PRODUCTS ARE RECEIVED BY THE
NWS TELECOMMUNICATIONS GATEWAY... THEY ARE PACKAGED WITH
OPERATIONAL UPPER AIR PRODUCTS INTO COLLECTIVE PRODUCTS
CONVERTED INTO BUFR FORM. THESE PRODUCTS ARE THEN BROADCAST
OVER NOAAPORT. THE INDIVIDUAL... COLLECTIVE AND BUFR
MESSAGES ARE ALSO TRANSMITTED FROM THE NWSTG TO NWS
CUSTOMERS OVER A VARIETY OF COMMUNICATION SERVICES.

THE FORMAT OF THE TEST MESSAGES WILL BE THE SAME WMO FORMAT
FOR CODED UPPER AIR MESSAGES AS USED BY RRS SYSTEMS SINCE
2005. THE NUMBER OF LEVELS IN THE KSTA CODED MESSAGES WILL
BE SIMILAR TO THE CODED MESSAGES ROUTINELY TRANSMITTED FROM

SUBJECT: AMENDED: UPGRADE TO REAL TIME OCEAN FORECAST SYSTEM:
EFFECTIVE NOVEMBER 4 2009
REFER TO: TECHNICAL IMPLEMENTATION NOTICE /TIN/ 09-30
TRANSMITTED ON SEPTEMBER 14 2009.
AMENDED TO POSTPONE THE IMPLEMENTATION DATE UNTIL WEDNESDAY
NOVEMBER 4 2009.
ON NOVEMBER 4, 2009...BEGINNING WITH THE 0000 UTC COORDINATED
UNIVERSAL TIME /UTC/ RUN...THE NATIONAL CENTERS FOR
ENVIRONMENTAL PREDICTION /NCEP/ WILL MAKE SEVERAL CHANGES TO
THE REAL TIME OCEAN FORECAST SYSTEM /RTOFS/. THESE CHANGES
ARE EXPECTED TO IMPROVE PERFORMANCE OF THE ATLANTIC FORECAST
AND ASSIMILATION SYSTEM.
THE MODEL CHANGES INCLUDE:
1. CHANGE SEA SURFACE HEIGHT /SSH/ ASSIMILATION QUALITY
CONTROL CRITERIA AND MASK TO EXPOSE MORE OF THE REGION TO
SSH DATA.
2. RESET BASIN AVERAGE SSH AND UPDATE MEAN DYNAMIC TOPOGRAPHY
TO BETTER MATCH OPEN BOUNDARY CONDITIONS.
3. ADD BOGUS SSH ANOMALY DATA OFFSHORE OF THE MID ATLANTIC
BIGHT TO CONTROL GULF STREAM PATH.
4. UPDATE TIDAL ELEVATIONS AND TRANSPORT BOUNDARY CONDITIONS
FROM THE GLOBAL INVERSE TIDE MODEL TPX07.
THE COMBINED EFFECT OF THESE CHANGES HAS RESULTED IN THE
FOLLOWING IMPROVEMENTS TO MODEL PERFORMANCE:
1. SIGNIFICANT REDUCTION IN SPURIOUS CURRENTS AND EDDIES IN
THE TROPICAL ATLANTIC AND EQUATORIAL ZONES.
2. MORE REALISTIC GULF STREAM AND LOOP CURRENT IN THE GULF OF
MEXICO WHICH COMPARES WELL WITH OBSERVED PATHS.
3. BETTER AGREEMENT WITH MEASURED TRANSPORTS FROM AOML CABLE
DATA NEAR 27 N FROM FLORIDA TO THE BAHAMAS.
4. SIGNIFCANTLY BETTER REPRESENTATION OF WATER TEMPERATURE
AND SALINITY AT THE WORLD OCEAN CIRCULATION EXPERIMENT /WOCE/
SECTIONS.
5. REDUCTION IN SST ERRORS WHEN COMPARED TO INSITU DATA.
6. SIGNIFICANT IMPROVEMENT IN REPRODUCTION OF MESOSCALE
FEATURES NEAR U.S. EAST COAST AS SHOWN IN INDEPENDENT SSH
ANALYSIS BASED ON JASON-1 AND JASON-2 ALTIMETER DATA.
DATA FORMAT VOLUME AND DELIVERY WILL NOT BE IMPACTED BY THIS
IMPLEMENTATION.
A CONSISTENT PARALLEL FEED OF DATA WILL BECOME AVAILABLE ON
