[ncl-talk] about the detailed formula of the function igradsF()

[Dennis Shea]

The NCL functions are interfaces to spherical harmonics from
SPHEREPACK, a suite of f77 based subroutines. Global data are
required. You can download the codes and examine the algorithms via:

How to do it?  Well, you have to provide the gradient information.


Good luck
