%description
The NCEP general interpolation library contains Fortran 90 subprograms to be used for interpolating between nearly all grids used at NCEP.
The library is particularly efficient when interpolating many fields at one time. It also contains routines for spectral transforms and other processing,
including those previously contained in the NCEPLIBS-sp library.

This is part of the NCEPLIBS project.

There are currently six interpolation methods available in the library:

  - bilinear
  - bicubic
  - neighbor
  - budget
  - spectral
  - neighbor-budget
