Re: variable definition

[Ansley Manke <manke@xxxxxxxxxxx>]

Hi Will,
If you have one variable already on the axis you want, and a second 
variable with the same number of items, you can regrid the second 
variable to use the axis of the first, using the @ASN transformation, to 
"assign" the data to the desired grid.   Say the new variable you have 
in the ASCII file has been read in onto a regular Z axis, and you've 
called it MY_PARM, and the variable from the model output is MODOUT. 
Then this will give you the parameters on the axis of the model data:

yes? let NEW_PARM = MY_PARM[GZ=MODOUT]
