RE: No GFS data on CONDUIT since FV3 update



They changed the directory structure on nomads/ftpprd of the GFS with todays upgrade. I had to update my grib filter scripts. Instead of the directory being gfs.YYYYMMDDHH, it is now gfs.YYYYMMDD/HH (where HH is the hour of the forecast run). I imagine that has something to do with it.

So this is interesting. In a local nfs server directory where the 0.25 gfs data out to 87h is saved, one file per forecast hour named something like

 

gblav0p25.19061206_F024

 

for the 12 UTC run, there was a directory created there named

 

gblav0p25.190612/

 

and in there were files named

 

1_F000

1_F003

1_F006

..

 

So it must have come through and keyed in on something, but the file naming scheme/structure must be different.

 

Here's the existing pqact line that created the above:

 

 

# 0.25 deg GFS analysis [huge]

CONDUIT ^data/nccf/com/gfs/prod/gfs.20(..)(..)(..)(..)/.*pgrb2.0p25.(anl)

        FILE    /data/grib2/gblav0p25.\1\2\3\4_F\5

#

# GFS Global 0.25 degree forecast out to 99h only

#

CONDUIT ^data/nccf/com/gfs/prod/gfs\.20(..)(..)(..)(..).*pgrb2\.0p25\.f(0[0-8].)

        FILE

        /data/grib2/gblav0p25.\1\2\3\4_F\5

 

 

So.. I do have the 12 UTC 0.25 deg GFS run every 3h out to 87h if anyone wants it for posterity. On that machine I don't save anything beyond.

 

Actually I just looked, and on our thredds server there is a similar folder/file saved - and it should have all of the data, out to 384h.

 

FWIW.

Pete

All,

 

I don't know if it wasn't transmitted on CONDUIT or if it was and the pqact info for it just changed, but we didn't save any GFS data from today's 12 UTC run - since it was updated to the FV3 version. Based on the volume of CONDUIT traffic this morning, the peak of the 12 UTC run increased from ~20 Gb/h to almost 35 Gb/h so something definitely changed.

 

 

 

Looks like the Unidata thredds server is also missing the 12 UTC data.

 

I'm capturing the output from ldmadmin watch -f conduit running on our primary ingest server, so hopefully I'll be able to see what the data looks like coming through.

 

I'll let you know what I find - or if anyone else has any good info, please pass it along.

 

Thanks,

Pete
