----------------------------------------------------------------
  Initial Request
----------------------------------------------------------------

Hello,

when quilt=TRUE I'm finding that mode is impervious to my taking away the obs=fcst line in the config file and specifying different threshold sequences for both.

It works only if quilt =FALSE, using a single threshold and convolution radius.

Any ideas?

Sample forecast, ob and config file attached.

Regards
Marion

Subject: Using mode with quilt and different threshold sequences for forecast and observation
From: John Halley Gotway

Hi Marion,

I see you have a question about the quilt option in MODE.  I just ran
a
test using the met-8.1 release and see that it's behaving as expected.
Let
me explain what I did to see if that sheds some light on the the
issue.

First, I defined separate convolution radii and threshold for the fcst
and
obs dictionaries, as shown below:



*fcst = {...   conv_radius        = [5, 10];   conv_thresh        =
[>=2.5,
>=1.25 ];*
*...*


*}obs = {...*

*  conv_radius        = [6, 12];   conv_thresh        = [>=3, >=1.5
];*
*...*

*}*

I ran this example twice, once with QUILT = FALSE and once with QUILT
=
TRUE.
Then I cat-ed the "*_obj.txt" output files together and looked at the
unique entries in columns 12 - 15:

cat out_QUILT_is_FALSE/mode*_obj.txt | awk '{print $12, $13, $14,
$15}' |
sort -ru


*FCST_RAD FCST_THR OBS_RAD OBS_THR5 >=2.5 6 >=310 >=1.25 12 >=1.5*

cat out_QUILT_is_TRUE/mode*_obj.txt | awk '{print $12, $13, $14, $15}'
|
sort -ru




*FCST_RAD FCST_THR OBS_RAD OBS_THR5 >=2.5 6 >=35 >=1.25 6 >=1.510
>=2.5 12
>=310 >=1.25 12 >=1.5*

This is exactly what the output is designed to be.  With QUILT =
FALSE, we
get objects for 2 runs of MODE:
   first radius/first threshold combo
   second radius/second threshold combo

With QUILT = TRUE, we get output for 4 runs of MODE:
   first radius/first threshold combo
   first radius/second threshold combo
   second radius/first threshold combo
   second radius/second threshold combo

And I checked to make sure that the requested forecast radii (5 and
10) and
observation radii (6 and 12) show up in the right spots.  So I don't
see
any obvious problems.

But I can run the example case you sent to see if anything else pops
up.

Thanks,
John Halley Gotway

Marion,

I ran the test case you sent, using 2 radii and thresholds from your
lists,
quilt=true, and again see the expected behavior.  See below.  So where
is
the confusion coming in?  Is this not the behavior you expected?  Or
is
there some other problem I'm not seeing?

Thanks,
John

fcst = {
   conv_radius       = [5, 6];
   conv_thresh       = [>=4.7, >=5.6];
}
obs = {
   conv_radius       = [5, 6];
   conv_thresh       = [>=2.5, >=3.2];
}

cat out_mm/mode*_obj.txt | awk '{print $12, $13, $14, $15}' | sort -u

FCST_RAD FCST_THR OBS_RAD OBS_THR
5 >=4.7 5 >=2.5
5 >=5.6 5 >=3.2
6 >=4.7 6 >=2.5
6 >=5.6 6 >=3.2

There is output for the 4 expected permutation of radius/threshold.

Hi John,

let me try your version and see whether it does what I am expecting it
to do.

Maybe I didn't explain it very well, but I want to create a quilt plot
using different intensity thresholds for the forecast and
observations. This is because there is a pretty big bias between the
two and using the same thresholds for both really overwhelms all other
signals. This info is useful up to a point. The cheap option, I
thought was to get a set of thresholds from a quantile mapping which
effectively removes the bias. The expensive option (in terms of
storage) would be to pre-process each forecast field and then use the
same thresholds again.

When I supplied the two different threshold sequences and took away
the obs= fcst, it ran but the postscript summary page (1) indicates
that the SAME thresholds had been used, despite what I had specified.
This is NOT what I had expected.

It was only when I took the sequences away that I got the ps output to
show that different thresholds had been used. I had turned
quilt=FALSE. I hadn't tested it with quilt=TRUE and specifying only
one intensity threshold.  I will do that, and consider your dictionary
definition below, and get back to you.

Regards
Marion

Hi John,



I've run the following setup with quilt=TRUE, different thresholds for
obs and forecast. I've attached sample output. This shows that it has
apparently applied two different thresholds to the fields.

I don't see any difference between what you did and I tried to do in
terms of syntax to expand the highlighted lines to include more than
one intensity threshold though… I will try that again.



Marion



fcst = {

   conv_radius       = [1,2,3,4,5,6,7,8,9,10,11]; // in grid squares

   conv_thresh       = [>=3.9];  --> sequence

   vld_thresh        = 0.5;

   filter_attr_name   = ["AREA"];

   filter_attr_thresh = [>=10.0];

   merge_thresh      = [>=3.5];  --> sequence

   merge_flag        = BOTH; // options are none, thresh, engine, both

}



////////////////////obs = fcst;



obs = {

    conv_radius       = [1,2,3,4,5,6,7,8,9,10,11]; // in grid squares

   conv_thresh       = [>=2.];   --> sequence

   vld_thresh        = 0.5;

   filter_attr_name   = ["AREA"];

   filter_attr_thresh = [>=10.0];

   merge_thresh      = [>=1.9];   --> sequence

   merge_flag        = BOTH; // options are none, thresh, engine, both

}

Marion

Hi John,

ok, so this is VERY odd. I have now reinstated my thresholds in the
config file and it is now showing output using the different
thresholds... see attached.

However, I have now managed to replicate the memory fault with one of
the files... this did NOT happen yesterday.... I think I am going
slightly mad...!

*FCST_RAD FCST_THR OBS_RAD OBS_THR5 >=2.5 6 >=310 >=1.25 12 >=1.5*

cat out_QUILT_is_TRUE/mode*_obj.txt | awk '{print $12, $13, $14, $15}'
| sort -ru




*FCST_RAD FCST_THR OBS_RAD OBS_THR5 >=2.5 6 >=35 >=1.25 6 >=1.510
>=2.5 12
>=310 >=1.25 12 >=1.5*

This is exactly what the output is designed to be.  With QUILT =
FALSE, we get objects for 2 runs of MODE:
   first radius/first threshold combo
   second radius/second threshold combo

With QUILT = TRUE, we get output for 4 runs of MODE:
   first radius/first threshold combo
   first radius/second threshold combo
   second radius/first threshold combo
   second radius/second threshold combo

And I checked to make sure that the requested forecast radii (5 and
10) and observation radii (6 and 12) show up in the right spots.  So I
don't see any obvious problems.

But I can run the example case you sent to see if anything else pops
up.

Thanks,
John Halley Gotway

Subject: Using mode with quilt and different threshold sequences for forecast and observation
From: marion.mittermaier at metoffice.gov.uk

John,



try using the attached observation file with the same forecast file
and see what you get...? I must be losing my marbles. The run script
uses this combination and did run before. I swear! We’ve got a whole
bunch of output to prove it (using obs=fcst), and I’ve just checked
that. Using the same thresholds does not result in a failure. There is
something about using different thresholds which seems to be causing
this failure.



Regards

Marion

Marion,



I ran the test case you sent, using 2 radii and thresholds from your
lists, quilt=true, and again see the expected behavior.  See below.
So where is the confusion coming in?  Is this not the behavior you
expected?  Or is there some other problem I'm not seeing?



Thanks,

John



fcst = {

   conv_radius       = [5, 6];

   conv_thresh       = [>=4.7, >=5.6];

}

obs = {

   conv_radius       = [5, 6];

   conv_thresh       = [>=2.5, >=3.2];

}



cat out_mm/mode*_obj.txt | awk '{print $12, $13, $14, $15}' | sort -u



FCST_RAD FCST_THR OBS_RAD OBS_THR

5 >=4.7 5 >=2.5

5 >=5.6 5 >=3.2

6 >=4.7 6 >=2.5

6 >=5.6 6 >=3.2



There is output for the 4 expected permutation of radius/threshold.

Subject: Using mode with quilt and different threshold sequences for forecast and observation
From: John Halley Gotway
Time: Fri Jun 21 10:02:47 2019

Marion,

OK, so you're checking the PostScript output files.  I understand the
problem you're describing, but I just don't see that behavior in the
output.

To clarify, I ran the data you sent through MODE using 2 radii and 2
thresholds (different in the fcst and obs dictionaries) and quilt =
TRUE:
quilt = TRUE;
fcst = {
...
conv_radius        = [5, 10];
conv_thresh        = [>=2.5, >=1.25 ];
...
}
obs = {
...
conv_radius        = [6, 12];
conv_thresh        = [>=3, >=1.5 ];
...
}

This run produces 4 MODE PostScript files:
mode_000000L_20180701_120000V_000000A_R1_T1.ps  (5 >=4.7 5 >=2.5)
mode_000000L_20180701_120000V_000000A_R1_T2.ps  (5 >=5.6 5 >=3.2)
mode_000000L_20180701_120000V_000000A_R2_T1.ps  (6 >=4.7 6 >=2.5)
mode_000000L_20180701_120000V_000000A_R2_T2.ps  (6 >=5.6 6 >=3.2)

After each I've listed the combination of FCST_RAD FCST_THR OBS_RAD
OBS_THR
that were used for that run.  And I double-checked the first page of
the
PostScript output to confirm that the settings there are correctly
applied.

So I can't replicate the problem you describe.

If you're interested in debiasing the forecast, you could use the new
percentile threshold options in met-8.1.  In the obs dictionary, set:
   conv_thresh       = [>=2.5, >=3.2];
And in the fcst dictionary, set:
   conv_thresh       = [==FBIAS1, ==FBIAS1];

Thanks,
John
