AWIPS CHANGE NOTICE NO AC055
IMPLEMENTATION DATE  JUNE 29 2004

[AC055] ON THE ABOVE DATE, THE FOLLOWING NCEP ETA MODEL PRODUCTS WILL BE ADDED 
TO
THE AWIPS/SBN  DATASTREAM (NWSTG2 CHANNEL) IN A TEST MODE.  WHEN TESTING AND
EVALUATION ARE COMPLETED, USER  WILL BE NOTIFIED OF A OPERATIONAL IMPLEMENTATION
DATE.

DAVE NIVER [301] 713-9001 EXTENSION 168 AND BRIAN GOCKEL[301] 713-0304 
EXTENSION 158
ARE THE COGNIZANT TECHNICAL INDIVIDUALS.  ANTHONY ROBINSON [301] 713-1373 
EXTENSION
165 IS THE DRG FOCAL POINT FOR THIS  ITEM.

THE FOLLOWING GRIDDED (GRIB2-FORMAT) NCEP ETA MODEL PRODUCTS WILL BE ADDED TO 
THE
AWIPS/SBN DATASTREAM:

WMO HEADER
------------

L?B??? KWBE

M?B??? KWBE

NOTES: THE FOUR NOTES BELOW CONCERN THE WMO HEADER ASSIGNMENT:

1.  THE SECOND CHARACTER IN THE WMO HEADER IS ASSOCIATED WITH THE PARTICULAR
PARAMETER  CONTAINED IN EACH GRID:
 H=Height                      P=Pressure (surface pressure, standard reduction
MSLP,  tropopause pressure, and maximum wind level pressure)
 T=Temperature                 Q=Lifted Index (parcel and best)
 R=Relative Humidity           W=CAPE (surface and BL 0-180 ml)
 U=u-Wind                      Y=CIN (surface and BL 0-180 ml)
 V=v-Wind                      S=Snow (water equivalent accumulated snow depth 
and
snow  depth)
 O=Vertical Velocity           A=Surface + Cloud (surface maximum/minimum
temperature,  surface wind speed and direction, surface dewpoint, total cloud 
cover,
and visibility)    C=Absolute Vorticity          D=Probability Parameters
(thunderstorm probability, frozen  precipitation probability, freezing 
precipitation
probability, and precipitation  probability)
 E=Total Precipitation         M=Categorical Parameters (categorical rain,
categorical  freezing rain, categorical ice pellets, and categorical snow)
 G=Convective Precipitation    Z=MSLP Eta Redux or Helicity
 F=Precipitable Water          X=Surface Lifted Index

2. THE THIRD CHARACTER IN THE WMO HEADER (ALWAYS "B") CORRESPONDS TO CONUS GRID 
218,
WHICH  IS 12 KM HORIZONTAL RESOLUTION.

3. THE FOURTH CHARACTER IN THE WMO HEADER CORRESPONDS TO THE FORECAST TIME.

  IF THE HEADER STARTS WITH "L" THEN A FOURTH CHARACTER OF "A" CORRESPONDS TO A
ZERO-HOUR  FORECAST, "B" CORRESPONDS TO A SIX-HOUR FORECAST, ETC.
  IF THE HEADER STARTS WITH "M" THEN A FOURTH CHARACTER OF "B" CORRESPONDS TO A
THREE  HOUR FORECAST, "E" CORRESPONDS TO A NINE-HOUR FORECAST, "H" CORRESPONDS 
TO A
FIFTEEN-HOUR FORECAST,  ETC.

4. THE FIFTH AND SIXTH CHARACTERS IN THE WMO HEADER CORRESPOND TO THE LEVEL.  
FOR
EXAMPLE,  "98" CORRESPONDS TO THE SURFACE, "99" CORRESPONDS TO 1000 MB, AND "50"
CORRESPONDS TO 500 MB.

THIS PRODUCT WILL BE AVAILABLE FOUR TIMES PER DAY, IN ASSOCIATION WITH NCEP'S 
00,
06, 12,  AND 18UTC EXECUTIONS OF THE ETA MODEL.

FOR FOS/NOAAPORT AND NON-AWIPS CUSTOMERS - IF YOU  HAVE ANY
QUESTIONS REGARDING ROUTING OR WOULD LIKE TO ADD THESE
PRODUCTS TO YOUR DATASTREAM PLEASE CONTACT.
