4.3.17 SHTWGZ

1.
Function
Performs the inverse Legendre transformation, which corresponds to the latter half of the inverse spectral transformation, only for the zonal component.

2.
Definition
Transforms wave data Wm(&phi)into grid data G(&lambda,&phi) only for the zonal component m=0. See SHTW2G for equations of transformation.

Call
SHTWGZ(JM,IM,WZ,G)
