Doug,

I not sure if the problem is the request is too strict or there is a
problem with gribtonc. First, I would suggest making the request more
liberal and see if the fields are populated. If that doesn't help then I
would have to check if the data is being processed correctly via gribtonc.

Here's a more liberal request:

 HDS     ^(H[HRT][I-P][C-Z]..) KWB.

[C-Z] should give all the forecasts, some params are only on certain
forecasts, etc.


Here's the pqact entry from motherlode for the raw data:

#  Spectral grids - grids A,B,C,D Global grid  Forecasts (wind & waves,
temperature)
##
HRS     ^H[A-Z][ABCD][A-Z][0-9][0-9] KWB. ([0-3][0-9])([0-2][0-9])..
        FILE
        data/pub/raw/hrs/model/spectral/(\1:yyyy)(\1:mm)\1\2_WAVE.wmo
