calc_gaussian_latitudes(nlat)	Calculate the gaussian latitudes (in degrees) and quadrature weights.
calc_geodesic_points(m)	Calculate the lat/lon values of the points on the surface of the sphere corresponding to a twenty-sided (icosahedral) geodesic.
calc_legendre_functions(lat, ntrunc)	Calculate associated legendre functions for triangular truncation T(ntrunc), at a given latitude.
calc_spherical_harmonic_coefficients(ntrunc)	Calculate indices of zonal wavenumber (indxm) and degree (indxn) for complex spherical harmonic coefficients.
transfer_grid2spectral_transform(grid_data, ...)	Transform grid data to spectral representation (spherical harmonic analysis).
transfer_spectral_transform2grid(spec_data, ...)	Transform spectral data back to grid space representation (spherical harmonic synthesis)
