20000911: surface data images

Tom,

I logged in, and see something that appears to be a problem with
the script sfc_namerica2.csh which is producing the
gif images.

The gdcntr invocation in the script uses GDATTIM = all, which
will loop through all the grid times in the file. But, you are only
producing a single latestus2.gif image of the last surface hour
(the dattim is set in the sfmap << EOF03 section). 

What you probably want here is to change GDATTIM = all to GDATTIM = last.
If I'm interpreting the script correctly, then this will sync up your
sfmap time with the lastest available grid time in the grid file.
I copied sfc_namerica2.csh to sfc_namerica2.csh.sav and made this change
to the running version.
The web page:
http://weather2.ca.uky.edu/ldmdata/images/us2_ani.gif
appears to have the correct analysis for 12:00.

In general, you would only want to use "all" with clear=yes to
produce a series of gif file outputs (with the .# extensions),
but that isn't what the script is doing. If this same script is working under 
solaris,
then you probably are just getting the lastest gdcntr plot overtop
of the previous times. In any case, that would make the script run much slower 
since it is doing 24 plots by the end of the day instead of 1.
