Thanks for getting back to me. I think the function I want to use is rect_to_curv, because I'm trying to put a variable, let's say TEMP[100,122], onto the curvilinear grid. The curvilinear grid coordinates are held in variables TLONG[100,122] and TLAT[100,122].
I'll show you what they look like: TEMP --> TLONG --> TLAT
I can do the following successfully:
shade TEMP, TLONG, TLAT
However, I want to save this output as a new variable. I tried this with "rect_to_curv" without success.
let temp_curv = rect_to_curv(TEMP, TLONG, TLAT, 3)
Bailing out of external function "rect_to_curv":
input grid not modulo, output grid must be inside input grid
**ERROR: error in external function
Hope there is a simple solution to this. The grids are the same size.

This is what's called in the Ferret documentation a "curvilinear grid". There are techniques for visualizing data on these grids directly and also capabilities for regridding to and from such grids. Have a look at the Ferret documentation under "curvilinear grids" and "curvilinear coordinates" and see if that'll get you started..
