There is a Fortran package available from NCAR (ftp.ncar.ucar.edu) to
compute spherical harmonic transforms (either direction) on regular or
Gaussian lat-lon grids.

Try: http://http.ucar.edu/SOFTLIB/SPHERE.html

You can call Fortran from IDL, although I haven't tried to call this
particular library.
