Initial Request
----------------------------------------------------------------
Hi, there,
This is another quick question. Is there a way to run PB2NC outside of a
loop? I am verifying a model with a valid time every hour of the day, and
I want to loop by valid time, but I don't want to run PB2NC inside the
loop. Since the bufr file has data for every hour of the day, I just want
to run PB2NC just once and then loop by valid time. How do I do that?
Thanks!
Perry

If I understand correctly, you should be able to set
PB2NC_SKIP_IF_OUTPUT_EXISTS and set the output filename to only
include
YYYYMMDD. For each loop iteration, it will see that the output already
exists and not run PB2NC. Is that what you mean?

Subject: running PB2NC outside of a loop
From: perry.shafran at noaa.gov
Time: Thu May 07 12:13:33 2020
Yes. I think I have an idea how to do this, now I that I think about
it.
Currently, I write out the prepbufr file with a date/time stamp, but I
guess I don't need to do that. If I wrote it out without a time
stamp, it
would only write out a file once.
Still, it would be good to be able to run PB2NC once and not bother
with
seeking out more files by being inside a loop. Is there a way to run
PB2NC
without being in a loop iteration?
Thanks!

Subject: running PB2NC outside of a loop
From: George McCabe
Time: Thu May 07 12:26:49 2020
Currently, no. The looping applies to all wrappers specified. We have
discussed ways to have different intervals for different tools, but I
think
the logic would get very complicated very quickly. We have also
discussed
having an exclude list to skip certain hours, but that would also
apply to
all wrappers.
If we changed the logic for PB2NC to skip the forecast lead list and
just
process once per run time, that would skip a lot of necessary runs if
you
were looping by init time, because the valid time will change for each
forecast value.
I suppose we could set it up for PB2NC to skip the forecast lead list
if we
are running by valid time since those data should always be based on
valid
time. That seems to make sense to me. This is essentially accomplished
with
the SKIP_IF_OUTPUT_EXISTS logic, but if we skip the loop, then you
could
turn off SKIP_IF_OUTPUT_EXISTS to overwrite daily files if you needed
to.
I'll run it by John to see if he sees any issues with doing that.

OK, thanks! I'm OK with all of that. You can then close this ticket,
and
I'll probably figure something else out.
