NOVICE USER QUESTION

[Charles Seman]

Michael:

Please try the following in your "VARS" record section in GRADS.ctl:

WindSpd   9  99  Wind Speeds

...you can check out the documentation at web site
http://iges.org/grads/gadoc/descriptorfile.html#VARS

-----

The format of the variable records is as follows:

      varname levs units description

-----

also, you may want to check out the various OPTIONS specifications
available at:

http://iges.org/grads/gadoc/descriptorfile.html#OPTIONS

and for general documentation (not sure if you've checked this out yet?):

http://iges.org/grads/gadoc/descriptorfile.html#TOP

I hope this helps,
Chuck
