NCEP Home > NCO Home > Production Management Branch > RAP13wmo Headers

NCEP distributes output from the Rapid Refresh (RAP) model on pressure levels on a 13km output grid. This data is being disseminated via NOAAPORT and the SBN with the following WMO headers:

T1T2A1A2ii   CCCC

where:

CCCC = KWBG

T1= L (GRIB2 Products)

T2= H - Height U - U component of wind/storm motion

T - Temperature V - V component of wind/storm montion
R - Relative Humidity O - Vertical velocity
P - Pressure W - CAPE
Y - CIN Z - Helicity
Q - Lifted Indices F - Precipitable Water
E - Total Precipitation G - Convective Precipitation
M - Categorical Parameters S - Snow Products
J - Precipitation rate N - Wind Gust
K - Visibility H - PBL height


A1= D (NCEP grid 130 - 13 km CONUS)

A2= A - 00 hour forecast B - 01 hour forecast
