Development files for Spherepack scientific library
SPHEREPACK is a collection of FORTRAN programs that facilitates computer
modeling of geophysical processes. The package contains programs for computing
certain common differential operators including divergence, vorticity,
gradients, and the Laplacian of both scalar and vector functions. Programs are
also available for inverting these operators. For example, given divergence
and vorticity, the package can be used to compute the velocity components.
The Laplacian can also be inverted and therefore the package can be used
to solve both the scalar and vector Poisson equations. Its use in model
development is demonstrated by a sample program that solves the time-dependent
non-linear shallow-water equations. Accurate solutions are obtained via the
spectral method that uses both scalar and vector spherical harmonic transforms
that are available to the user. The package also contains utility programs
for computing the associated Legendre functions, Gauss points and weights,
and multiple fast Fourier transforms. Programs are provided for both
equally-spaced and Gauss distributed latitudinal points as well as programs
that transfer data between these grids.
