[McIDAS #IWJ-443798]: MCIDAS Software Upgrade at NGC

Hi Randy,

Sorry for taking so long to get back to you (so you could investigate before the
weekend).  We were finishing off configuring a server machine we are sending
to New Orleans for the AMS meeting.

There should be no changes in Unidata McIDAS that alter how NEXRAD Level III 
data is
processed (i.e., I made no changes).

> I notice a ps -ef |grep DM reveals that DMNEXR is running.

I seem to remember that someone there (perhaps Martha) adopted the approach we 
use to
"process" NEXRAD Level III data -- we FILE the images directly in an LDN 
action; we
do not use the DMNEXR approach that SSEC created.

I would suggest that your troubleshooting should include the following:

- turn off DMNEXR processing (if you actually are using the FILE approach
  that we suggest)

  <as 'mcidas'>
  cd $MCDATA

- verify that you have the FILEing setup in an LDM pattern-action file

  The action we suggest is:

# All NEXRAD Level III products
NNEXRAD ^SDUS[23578]. .... ([0-3][0-9])([0-2][0-9])([0-6][0-9]).*/p(...)(...)
        FILE    -close

  Of course, you will likely need to change the directory where Level III
  images are to be written to match your setup.

  Also, you need to make sure that your ADDE dataset definition for the RTNEXRAD
  dataset (if that is what you are calling it) "points" to the directory 
  that are used in your LDM action.

  And, of course, your LDM needs to actually be running a 'pqact' instance that
  processes the NEXRAD3 (aka NNEXRAD) data.
