[McIDAS #USW-595984]: 20200416: GLM imagery / McIDAS / CoD processing

Hi Mike,

re:

Hmm...

These look correct to me!

This looks correct as well.

The next thing to try is turning on 'trace'ing to see what the server is
complaining about:

imglist.k NPGOESRL/GLMGE3 FOR=ALL TRACE=1

A file named 'trce' should be created in the first writable directory included 
in
the MCPATH definition that was in-scope when the 'imglist.k' was run.  Do a 
'less trce'
to see what the server has to say.  If there is not enough infomation in the 
abbreviated
listing, you will need to edit abinaget.cp and change the setting of DEBUG from 
'0'
to '1', '2', or '3'.  Each debug level will result in more output in the 'trce' 
file.

NB: you should delete the 'trce' file between runs where TRACE=1 is specified,
otherwise the new output will be written to the end of the file, and it will
get harder and harder to wade through the output to find the clue that you
need.

The ADDE dataset group and descriptor names are not important.  What is
important is how the set of files (DIRFILE= regular expression) is defined.

I can login and poke around to see what I can see if you like.  Recall that
I have SSH access to climate.

re:

OK.

re:

The stretch table is not crucial at all.  I just used it to accentuate
the display.

v2020 should not work correctly (fully?) with the Vlab GLM products as
it did not have the needed definitions in abinparm.inc, etc.

re: providing your set of min/max values for Level2 products

OK, sounds good.

re: We have no resources or intentions to pick up the activity internally
especially since the Vlab GLM L2/L3 products are very usable, prehaps even
more than the TTU images. The thing that is missing (and will NOT be added)
is CONUS/PACUS coverage.

I think that the next move(s) is(are) to get some debugging output from
the ABIN AGET server.  Hopefully, this will tell us what is going on
(or not going on as the case may be).

Cheers,

Tom
