Initial Request
----------------------------------------------------------------
Good afternoon,
I apologize if this has a simple answer, but I was wondering if there is a
way to deal with missing data using pcp_combine using the -add flag. For
instance, if I am summing 3 fields (not precipitation) and one of them
contains missing data as NaNs, is there a way that the output from
pcp_combine can also be NaN or some sort of missing data flag?
Thank you!
Mike

Mike,
I am totally shocked! It *should* be the case that if any of the
input
values at a grid point contain a missing data value, then the output
does
as well. But to my amazement, that is not currently happening, which
is
obviously what you've run across.
Inspection of the met-8.0 code reveals that the logic is correct for
the
-sum and -subtract commands but is not correct for the -add command.
For -add, pcp_combine initializes the output to the first input field.
When processing subsequent fields, it just skips over any bad data
values
without updating the output value to bad data. So it's really just a
one
line fix that's required.
But we really need to fix this functionality ASAP. I'll post a patch
for
met-8.0 pcp_combine.cc to fix this.
Thanks for finding this issue!

Mike,
I just posted a patch to met-8.0 for this here:
https://dtcenter.org/met/users/support/known_issues/METv8.0/index.php
It's basically a one-line change.
I'll ask Julie Prestopnik to include this patch whenever she
recompiles MET
in the variety of builds she handles. What are the steps for applying
a
patch at WPC?
Thanks,
John

Hi John,
Thanks for the quick fix! We probably have to contact NCO to apply the
patch for WPC on the netapp.
Jim, is this a ticket to NCO?
Thanks,
Mike

Mike,
This is a ticket to NCO if they need to recompile.
Maybe Julie and Mike should be involved in this one to explain the
ticket.
We can take up this matter on Monday.
Today is a critical weather day and no ticket will likely even make it
into
the system.

I'm happy to help in any way I can. It would be great if they could
assign
the ticket to John Bell since he installed it. He and I could talk
about
the process, and it should be a pretty quick fix.

Hi Julie,
I'd be happy to send a ticket on Wednesday. I'm on leave through then
due
to some general craziness.
