I believe that I understand your objective.  I took the liberty of
logging onto your systems and think I have found the data you are
referring to on weather3.

Questions:

- which account do you want to use to look at this case study data?
- do you envision that you will want to be able to access the
  case study data remotely?

Reasons for the questions:

1) which account to you want to use to look at this case study data

If you want to use the 'mcidas' account on weather3, you have a bit
of a challange since the names of the data files in the case study
are the same as those used for the real time data.  The 'mcidas'
account is setup with McIDAS REDIRECTions that "point" (say where
to find) data files with "standard" names.  Here is a part of the
REDIRECT listing as 'mcidas' on weather3:

<as 'mcidas' on weather3>

As you can see, the REDIRECT patterns will match files in your
case study dataset.  Because of this, you will likely run into
things that don't seem to make sense (because you don't use
McIDAS enough to be comfortable with some fundamental concepts).

To get around the sticky bits, I suggest that you access the
case study data from an account other than 'mcidas'.  What about
using your own login account (sebenste)?

If you are game, then do the following:

1) login as yourself (sebenste)

2) edit your .cshrc file and add the following defines needed
   for McIDAS access:

setenv MCHOME /home/mcidas
if ( -e $MCHOME/admin/user_env.csh ) then
  source $MCHOME/admin/user_env.csh
endif

3) logoff and then log back on as 'sebenste'

4) make the directories needed for McIDAS:

mkdir -p ~sebenste/mcidas/data

At this point, you should be able to run McIDAS as yourself.  The
next steps will be the setting up of McIDAS ADDE datasets for
your case study data:

<still as 'sebenste'>
cd $MCDATA

- first, setup McIDAS ADDE REDIRECTions to be able to find the
  data in the case study:

redirect.k ADD AREA0\* \"/home/httpd/html/falout/mace_case/mcidasd
redirect.k ADD MDXX0\* \"/home/httpd/html/falout/mace_case/mcidasd

- next, setup ADDE datasets for the image and POINT data:

The set of datasets defined here are overkill for the case study data you
have (because you don't seem to have SHIPBUOY, NGMMOS, SYNOPTIC, etc. POINT
data), but defining all possible datasets can't hurt, plus it is illustrative
of the process.

After defining the ADDE datasets, you should be able to create the
displays you want.  Here are some examples:

First, start a McIDAS session:

mcidas -config

-- set the size of the image window that you will want (lines and elements)
   and any other thing you think will be useful.  Make sure that the
   Save configuration values to defaults file is set to YES before
   clicking on Start.

From the McIDAS Text and Command window, verify that you can access the
datasets you created:

DSSERVE LIST MACE

IMGLIST MACE/GE-IR.ALL

IMGDISP MACE/GE-IR STA=KMIA MAG=1 EU=IMAGE SF=YES REFRESH='EG;MAP VH'

PTLIST MACE/PTSRCS FORM=FILE ALL

ERASE
SFCPLOT T NACONF 12 1997/MM/DD DAT=MACE/SFCHOURLY       <- change MM and DD to 
the appropriate
                                                           month and day of 
your data

ERASE
UAPLOT 72469 12 1997/MM/DD DAT=MACE/UPPERMAND MACE/UPPERSIG  <- ditto comment 
above

So, the bits you have to pay attention to are:

- specifying the date of the data you want to plot (year, month and day)
- explicitly specifying the dataset(s) to use (i.e., SFCPLOT & UAPLOT use of 
DAT= keyword)

Of course, all of the above can be done from the command line or in a script.
I figure you will probably want to play around in a McIDAS session first
so you can decide on the plots you want to generate.  After that, you can
create scripts that will create the plots and then save the displays as
GIFs, etc.

Questions:

- what other types of displays do you want to create?
- what is the ultimate goal?

Cheers,

Tom
