Glenn,

The pattern above is for our IDD. The /mETA is a meta data tag added on
to the product identifiers at injection since the old KWBC was not
sufficient for differentiation ETA, NGM, RUC, AVN products that used the same
headers. It is not a line feed. The meta tag is created by the pqing
program which ingests the model data into the LDM by looking at the
appropriate GRID pds process/center numbers and identifying the model.

I believe you will find now that KWBE is sufficient for ETA 207 & 211, while
KWBD is used for the 212.

That would  result in:

HRS     ^[YZ].[QT]... KWBE
        PIPE etc

and

HRS     ^[YZ].[R]... KWBD
        PIPE etc.

The @@@ in the dcgrib decoder I provide will be replaced by 211, 212, 207 etc
as decoded. The decoder also has the ### template that could be used to
identify the model number (085, 089) (in march, NCEP is supposed to
replace the model number of the ETA with 084 for all runs).
