Initial Request
----------------------------------------------------------------
John, when verifying cloud ceiling, I am using a filtered set up obs. I am
using this set of obs by setting the SID field in the MET point_stat config
file. I also have poly regions set. What I want is for MET to only verify
the various poly regions using the set of SID set of obs. When I run
point_stat, in my MPR file I get data for each poly region and the data for
the SID obs instead of having MET condition the obs first to the SID region
then break the results out by poly region. I attached my config file. Is
there a way to set up the config file to achieve what I am after?
Thanks
Bob Craig

Bob,
That's a very good question. I think I understand what you're trying
to
do. You have a list of stations that you deem acceptable. You'd like
to
configure Point-Stat to tell it which station id's to use and then
apply
various masking regions to those list of acceptable observations.
Unfortunately, I can't think of an easy way to configure Point-Stat to
do
that right now.
But here are some things to think about...
The "*sid_exc*" option does the opposite of what you want. It defines
a
"black list" of SID's that should be not used in the verification.
And
it's applied prior to defining polyline subdomains. So it would have
the
desired effect. You could try modifying your logic to list the
stations
that should be excluded rather than included.
Point-Stat and Ensemble-Stat could pretty easily be enhanced to
support the
use of a "sid_inc" option to do exactly what you want. If specified,
only
use obs for stations included in this list. But that'd be new
development
and is not currently available.
Another option, would be taking your long list of acceptable station
ID's
and breaking them down into your polyline masking regions. So you'd
have a
list of SID's for the NHEM_mask region, SHEM mask region, and so on.
But
that's pretty labor intensive and is much less flexible.
Do you think I should write up adding the "sid_inc" option as a new
development issue for MET?
Thanks,
John

Bob,
I wrote up this GitHub issue while the idea was still fresh in my
mind:
https://github.com/NCAR/MET/issues/1235
I also attached a PDF in the event that you can go look at GitHub.
Please
let me know if you think this task is worth doing.
Thanks,
John

John, I think the obs_inc option would be great. I am currently using
the obs_exclude for this but it becomes a huge list when you are just
wanting to use some selected ob sites to verify a particular model
parameter. I think it would be useful to a lot of MET users.
Thanks
Bob

Bob,
Good news. This was a nice, easy enhancement and I was able to get it
added yesterday for inclusion in the met-9.0 release:
https://github.com/NCAR/MET/issues/1235
I'll go ahead and resolve this issue.
Thanks,
John
