Hi Rob,
Thanks for the cdl file.
I'm not sure I know how to create 1.25 raw data from the ldm feed, and
the ldm is the source of my data.
For the older decoders I had an entry like this in my pqact file:
HRS ^H[UVHRP][I-P]... KWB. (..)(..).*(/mAVN|/mSSIAVN)
PIPE /usr/local/ldm/decoders/bin/gribtonc
-q "lin,dlat=1.25,dlon=1.25" decoders/etc/avn-1.25x1.25.cdl
data/GRIB/(\1:yyyy)(\1:mm)\1\2_avn-1.25x1.25.nc
Ruth,
Create raw file using FILE action in the pqact.conf with following entry:
HRS ^H[UVHRP][I-P]... KWB. (..)(..).*(/mAVN|/mSSIAVN)
FILE data/GRIB/(\1:yyyy)(\1:mm)\1\2_gfs_37-44.wmo
Here's how to create the 1.25 cdl
% gribtocdl -v -q "lin,dlat=1.25,dlon=1.25" < "raw file from above" >
gfs-1.25x1.25_37-44.cdl
You will still have to edit the cdl to make it 100% correct.
Robb...
I thought gribtonc was doing some interpolating because the -q
"lin,dlat=1.25,dlon=1.25" was an option to gribtonc. I think if i just
save everything that I get from HRS ^H[UVHRP][I-P]... KWB.
(..)(..).*(/mAVN|/mSSIAVN) into a file for a date, that it won't really
be 1.25 data. I'm not sure at all, but since I could get 2.5, 1.25 and 1
degree resolution from the same grib data, I thought it was gribtonc that
was doing the interpolating.
I could try saving all the grib data as above into a file and see what
gribtocdl does with it, but how it would create a 1.25 data file I don't
know. I have used gribtocdl before for existing grib files, but I'm a
little confused about how this would work.
Thanks some more,
Ruth

Hiya,
I attached gfs-1.0x1.0_3.cdl for the 1 degree grid, it might
needs some
minor modifications to make it 100% correct. I don't have
any
1.25 raw data to make that one. You can make the cdls
yourself with the
gribtocdl program. When making the 1 degree, I found some
bugs in the
gribtocdl program so I need to make a new release. It was
missing some
level info in the program. So release decoders-3.0.3 should
be able to
create the 1.25 one. Will let you know when I completed the
release.
