Arlene,

>next Monday.

Sure.

>The batch file (for the haines index) is not working on my archived data.

OK.

>Please note that my next chance to check my messages is Wednesday night.

I will answer this ASAP just in case you get a chance to logon earlier.

>The first map with TDIF57 is plotted correctly then the job fails.  See
>text of mcidas session below.

OK>

>The grid file is created as listed:

>/usr/arlene/mcidas/data% ls -l GRI*

Hmm...  The file certainly has a current time stamp, but the BATCH file
is setup to write to GRID file 1, not GRID file 132.  The first question
is what is updating GRID0132?

See, right here you are telling RAOBCON to write to MYDATA/GRIDS.1.
Given the definition of MYDATA/GRIDS above, the actual GRID file
should be GRID0001.  I am willing to bet that your McIDAS session
has a REDIRECTion for GRID0001 and that file is not writable by you.
The quickest way to test this wager is to add a REDIRECTion
for GRID0001 to your McIDAS-X working directory, /usr/arlene/mcidas/data:

REDIRECT ADD GRID0001 "/usr/arlene/mcidas/data

Looking through HAINES.BAT, I see that it will also want to read/write
to/from GRID0002.  You should, therefore, also add a REDIRECTion for
it.  The easiest way to do both is:

REDIRECT ADD GRID000* "/usr/arlene/mcidas/data

GRDLIST is telling us that it can't find GRID file GRID0001.

This problem looks like there is bad data in either the T or TD fields
for the times you are trying to plot.  I am suspicious of this because
of the 1/P1 and 1/P2 terms in the equation.

Since SFCPLOT and SFCCON (which run PTDISP and PTCON, respectively) can
both plot RH, I would suggest changing your BATCH file to run SFCCON
directly:

SFCCON RH OLAY 13 1998170 DAT=MYDATA/SFC0619

It could be that the subroutine that will calculate RH in this case will
trap missing data and, therefore, produce some usable output.

Let me know if these comments don't get you going.
