CHANGE NOTICE NO 10990
EFFECTIVE DATE  FEBRUARY 26 2008

[10990] ON THE ABOVE EFFECTIVE DATE THE FOLLOWING GLOBAL
FORECAST SYSTEM [GFS]-BASED GRIDDED MODEL OUTPUT STATISTICS
[MOS] GUIDANCE FOR ALASKA WILL BE ADDED TO THE SBN/NOAAPORT
DATASTREAM.  THE PRODUCTS WILL BE MADE AVAILABLE FOR TESTING
ON DECEMBER 4 2007.

REBECCA COSGROVE [301] 713-0023 EXTENSION 124 IS THE COGNIZANT
TECHNICAL INDIVIDUAL.  ANTHONY ROBINSON [301] 713-1373 EXTENSION
165 IS THE DRG FOCAL POINT FOR THIS ITEM.

THE FOLLOWING PRODUCTS WILL BE ADDED TO THE SBN/NOAAPORT
DATASTREAM:

PLEASE SEE INFORMATION BELOW FOR COMPLETE HEADER AND PRODUCT 
SIZE/PROJECTION INFORMAITON:

*WMO Headings for Gridded MOS Products*

WMO headings have the format of T_1 T_2 A_1 A_2 ii  CCCC

1.  The CCCC for all  gridded MOS product WMO headings is *KWBQ*.

2.  The T_1 for all gridded MOS products based on the global model is *L*.

3.  The T_2 represents the weather element type designator.  The 
following values are used for a T_1 = *L*.  When feasible, these values 
match those used for the NDFD WMO headers.

Values for T_2 are:

A = sky cover

B = wind direction at sensor height (nominally, 10 m)

C = wind speed at sensor height (nominally, 10 m)

D = probability of precipitation (12 h)

E = temperature at sensor height (nominally, 2 m)

F = dewpoint temperature at sensor height (nominally, 2 m)

G = daytime maximum temperature at sensor height (nominally, 2 m)

H = nighttime minimum temperature at sensor height (nominally, 2 m)

I = quantitative precipitation (6 h)

J = thunderstorms (6 h)

K = severe weather (6 h)

L = precipitation type

M = precipitation characteristics

N = precipitation occurrence

O = obstruction to vision

P = visibility

Q = ceiling height

R = relative humidity

S = snowfall amount (24 h)

T = apparent temperature

U = probability of precipitation (6 h)

V = quantitative precipitation (12 h)

W = wind gusts

X = thunderstorms (12 h)

Y = thunderstorms (3 h)

Z = unassigned

4.  The A_1 designates the geographical area.  The following designators 
follow the conventions established in the NDFD WMO headers.

A = Puerto Rico

*R = Alaska*

S = Hawaii

T = Guam

U = CONUS

5.  The A_2 and ii follow the convention established in the NDFD.  These 
three characters together represent the day and hour (UTC) for which the 
product is valid.  The following convention for A_2 and ii is used for 
the gridded MOS products:

A = Day 0; ii =  hour (0-23)

B = Day 1; ii =  hour (0-23)

C = Day 2; ii =  hour (0-23)

D = Day 3; ii =  hour (0-23)

E = Day 4; ii =  hour (0-23)

F = Day 5; ii =  hour (0-23)

G = Day 6; ii =  hour (0-23)

H = Day 7; ii =  hour (0-23)

I = Day 8; ii =  hour (0-23)

J = Day 9; ii =  hour (0-23)
