[McIDAS #BFX-595521]: Question about the stats of the EF5 Hackleburg Tornadic Supercell at 20:10



Hi Rod,

re:

> number. Is that possible?

Yes as long as you make sure that you change the TIME= values consistently
throughout the BATCH file.

NOTE: The output that you sent was very confusing given the extra lines, etc.
Also, some parts of the listing looked like more than one thing (e.g., BATCH
job) were running at the same time.

re:

File number?  The 'F' in LINELE=65 119 F stands for file coordinates.  Are
you sure that this is what you want?

Whatever works...

Given that you are working in File coordinates, it may be that you are
not sampling the portion of the image that you think you are sampling.

re:

Does what affect the "mean" statistics?

I don't know what you are asking (and I'm not too sure of what you described
above).

re:

The GVARINFO command will list the time of a GVAR image as long as the
image is in its original form (meaning that it still contains GVAR
line prefixes).  The effective radius images do not have this information
as they are products,  but the IR and VIS images you have do.  Unfortunately,
GVARINFO does not understand ADDE datasets; it is an old command that
only works with AREA files directly:

HELP GVARINFO
GVARINFO -- Displays information from a GVAR area line
   GVARINFO area_number line_number
Parameters:
   area_number | area number containing GVAR data
   line_number | line number in area coordinates; use T for table of
                 calibration changes
Keyword:
   BUG=201     | Run program in debug mode                       (def=101)
----------

This can be overcome in a couple of different ways:

- link the original image to an AREA file name

  Example:

cd $MCDATA
rm -f AREA2000 AREA2001
ln -s archive/27apr2011/2011117201000i13.c01 AREA2000            <- GVAR VIS 
image
ln -s archive/27apr2011/goes13.2011.117.201020.BAND_04 AREA2001  <- GVAR IR 
image

re:
> Is it in the IMGLIST FORM=ALL command?*

No.

re:
> *Thanks for your help! Looking forward to hear you response.*

No worries.

Cheers,

Tom
