[ncl-talk] Attaching coordinate information

[Barry Lynn]

Hi:

I have used the helpful suggestions offered through ncl-talk to create
the attached program that reads multiple GEFS files from multiple GEFS
directories (on your disk).

Of course, any one on the list can use this program, but I would like to
upload it again after I solve this problem.

As part of my calculations for the GEFS mean, I need to create a variable
called t2m_ave.  However, when I use it I get get the error below.

If I use a variable from the GEFS*grb files that I don't need in place of
it, I can make very nice plots of the mean surface temperature. This means
that these variables already have grid information attached to them.

The page: http://www.ncl.ucar.edu/Document/Graphics/error_msg.shtml

has a suggestion what to do, but I am not sure what "x" is, and how to use
the suggestion.

The upshot is that I need to attach geographical information to my "average
variables," and I don't know how to do this.
