Hi:
We have been getting AVN analysis data via LDM for a while with this
pqact entry:
HDS ^(H[HRT][I-P]A..) KWB.
([0-3][0-9])([0-2][0-9]).*(/mAVN|/mSSIAVN)
PIPE /usr/bin/gribtonc
-q "lin,dlat=1.25,dlon=1.25"
/usr/etc/avn-1.25x1.25.cdl
/pub/suomiday/level1a/ancMet/ancMet_(\2:yyyy).(\2:ddd).\3.00.0360_nc
Now we need forcast data, so we tried this modified pqact entry:
HDS ^(H[HRT][I-P]C..) KWB.
([0-3][0-9])([0-2][0-9]).*(/mAVN|/mSSIAVN)
PIPE /usr/bin/gribtonc
-q "lin,dlat=1.25,dlon=1.25"
/usr/etc/avn-1.25x1.25.cdl
/pub/suomirt/level1a/ancMet/ancMet_(\2:yyyy).(\2:ddd).\3.00.0360_nc
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
Robb...
(Note the C instead of the A in the first part of the regular expression
on the first line). This seems to result in lots of empty netcdf
files--files with all headers and attributes but no data. How does one
get AVN forecast data via LDM?
Thanks in advance for any hints,
Doug Hunt
