[ncl-talk] uv2sfvpf

[Alan Brammer]

The function is built-in, you do not need to load anything. 
The top of the documentation page tells you whether you need to load anything (typically since 6.1.2 you do not). 

The documentation specifies the input needs for the function.

This likely will not work with WRF, though that depends on your WRF set up.
