Initial Request
----------------------------------------------------------------
John, I am starting to code up our use of HiRA using MET. It seems to be
working with one exception. In the config file I identify a NETCDF
precipitation observation file to use as the climo file (persistence). When
I run point_stat, the climo mean fields in the MPR file are all set to NA.
The BSS_simple is calculated but not the BSS. I placed the data files on
AMERDEC.
My command line is:
/h/WXQC/met-6.1/bin/point_stat
/h/data/global/WXQC/data/wrf/t49/PS.AFWA_SC.U_DI.A_GP.WRF-GPOST_GR.L1P667KM_
AR.JAPANNORTH1KM_PA.GPOST_DD.20180519_CY.12_FH.006_DF.GR1
/h/data/global/WXQC/data/met/nc_obs/precip/nc_2018051918
/h/WXQC/met-6.1/data/config/PointStatConfig_precip_hira -outdir
/h/data/global/WXQC/data/met/ptstat/mdlob_pairs/hira/TP -v 3
Thanks
Bob

Hi Bob,
I see you have some questions about the HiRA method in MET. Thanks
for
sending sample data files. I wanted to let you know that I pulled
them
down from ARMDEC. However, I haven't had a chance to debug them yet.
I'll be in touch when I have an update for you.
Thanks,
John

Bob,
Thanks for sending your sample data files. I was able to run them
through
met-6.1 this morning and have a couple of suggestions.
(1) In you Point-Stat config file, you have this setting:
mask = {
grid = "FULL";
poly = [];
sid = "[]";
}
You should change that setting for the station ID mask to an empty
list
like this:
sid = [];
Just like the "poly" setting, the "sid" setting is an array of values.
The
default setting of two square brackets is an empty list.
(2) To answer your question about climatologies, MET processes
climatologies as gridded datasets. You're passing in a set of point
observations as the climatology, but the MET tools do not support
that. In
the past, all of the climatology data we've encountered has come in
the
form of gridded datasets.
This is, in fact, the first time this has come up. Does the Air Force
typically specify climatologies in terms of point observations rather
than
gridded datasets? If so, we could think about how we might adapt the
software to account for this difference.
Thanks,
John

Thanks John - We are currently using HIRA the way the MET Office does.
They persist the observation value and use as the reference. We
don't necessarily have to do it that way. Based on your answer, we
could persist the model analysis and use that as the climo field. I
understand you guys have been working with the MET Office about them
possibly switching over to MET. Has this issue come up in any
discussions? We typically try to do things like they do for better
inter-comparisons if possible. If they wanted you to add point based
observations as a climo source, then we would certainly use that
data.

Bob,
Ah, thanks for explaining where the use of persisted point
observations as
a reference climatology originated. I do not recall any discussions
with
the MET Office at that level of detail. So to my knowledge, this
issue has
not yet arisen.
Yes, you're correct. You should be able to use the model analysis as
the
climatology now. Please let me know what questions come up if/when
you try
that.
Tara, please jump in on this ticket if you have any more info about
the MET
Office's potential use of the MET software. We'll need to evaluate if
MET
should be enhanced to support the use of point observations as a
climatology.
Thanks,
John
