Spherical Coordinate Remapping and Interpolation Package (SCRIP)

Los Alamos Software Release LACC 98-45

SCRIP

SCRIP is a software package which computes addresses and weights for remapping and interpolating fields between grids in spherical coordinates. It was written originally for remapping fields to other grids in a coupled climate model, but is sufficiently general that it can be used in other applications as well. The package should work for any grid on the surface of a sphere. SCRIP currently supports four remapping options:

  • Conservative remapping: First- and second-order conservative remapping as described in Jones (1999, Monthly Weather Review, 127, 2204-2210).
  • Bilinear interpolation: Slightly generalized to use a local bilinear approximation (only logically-rectangular grids).
  • Bicubic interpolation: Similarly generalized (only logically-rectangular grids).
  • Distance-weighted averaging: Inverse-distance-weighted average of a user-specified number of nearest neighbor values.

SCRIP functionality has been included in the Earth System Modeling Framework and the European PRISM framework.
