Hello,

I'm using stat_analysis to do some filtering and looking at the Users'
Guide it looks like fcst_valid_beg and fcst_valid_end can be set as
YYYYMMDD with _HHMMSS as optional, so I have set in my config file
fcst_valid_beg = "20180601";
fcst_valid_end = "20180601";
fcst_valid_hour = [ "180000" ];
When I run stat_analysis, I see

DEBUG 2: Processing Job 1: -job filter -fcst_valid_beg 20180601_000000
-fcst_valid_end 20180601_000000 -fcst_valid_hour 180000

and get no stat lines retained. It looks like due to some hour minute
second information being appended to the date I provided (though I didn't
set it in this format in my config).

Now if I set my config to
fcst_valid_beg = "20180601_180000";
fcst_valid_end = "20180601_180000";
fcst_valid_hour = [ "180000" ];

and run I see
DEBUG 2: Processing Job 1: -job filter -model gfs -fcst_valid_beg
20180601_180000 -fcst_valid_end 20180601_180000 -fcst_valid_hour 180000

and I get stat lines retained.

So my question is are these config options not meant to be used in this way
together? It seems if it is okay to define fcst_valid_beg and
fcst_valid_end in YYYYMMDD that defining the hour information in
fcst_valid_hour would be okay (though I know it can be defined in
fcst_valid_beg(end)). I guess I am wondering if fcst_valid_hour is not
meant to be used if fcst_valid_beg and fcst_valid_end are defined.

Thanks!

Mallory

Mallory,

Yes, the fcst_valid_beg/fcst_valid_end and fcst_valid_hour filtering
settings are *not* meant to be combined.  They are applied totally
independently.

fcst_valid_beg = DATE/TIME means... only keep lines whose valid time
is >=
this
fcst_valid_end = DATE/TIME means... only keep lines whose valid time
is <=
this
fcst_valid_hour = list of TIMES means... take the forecast valid time
and
throw away the date.  Only keep lines whose time falls in this list of
times.

Here's how you might use them together:
-fcst_valid_beg 20190101 -fcst_valid_end 20190131_235959
-fcst_valid_hour 00

The above settings specify that we only want data for the month of
January
and only data valid at 00Z during that month.

Make sense?

Thanks,
John

Makes sense, thank you!
