REGRID Tutorial : Run pregrid
cd to pregrid directory:
cd pregrid
ls -l
and you should see this:

Edit pregrid.csh
- This is a cshell script that is put together to handle several
types of input data to pregrid.
- For the SOC case, the only variable you need
to be concerned with is the DataDir variable,
as this points to the location of your input file (if you
specify this variable wrong, you will get the error "set:
No match." during run time). All the other variables
have been set up for the SOC case already.
- Note that the input data for the SOC case is the NCEP ON84.
- Do check the parameters defined in the deck against what is
described in the Notes
(Chapter 15).
- Also click on the example pregrid.csh
to see highlighted parameters that need to be considered and
changed if you start to configure your own case, and use data
other than in the default script. For example, if your input
data is GRIB format, don't forget to select the right Vtables.
Type the following to run pregrid:
pregrid.csh >& log &
If you are successful, you should find these additional files
generated in the pregrid directory:

where log
is a log file of all print statements generated by pregrid program,
and files beginning with a prefix (such as ON84, SNOW and SST)
and a time stamp are binary output from pregrid in the intermediate
format. If you don't see these files, it would mean your pregrid
job has failed. In this case, check your script to see if you
have made any mistakes (such as where the input data file, NCEP_ON84.9303,
is located), or look in log file to find any clues.
Near the end of the log file, you should see the following line
if the job is finished correctly:
Normal
termination of program PREGRID_ON84
View intermediate files:
-There is a utility available for plotting the intermediated
files, it is called plotfmt
- cd to util
- make utility by typing (you need NCAR Graphics to use
this utility)
make
plotfmt
- run utility by typing
plotfmt
intermediate-file
eg.
plotfmt ../ON84_SST:1993-03-13_00
- view output with NCAR Graphics

gmeta
If everything checks out, then your attempt to run pregrid was
a successful one. You can now move to the next stage of the REGRID
program: regridder.
