Matlab scripts to generate grid description files used for cdo regridding.

Based on work by Jeremy Fyke, Andy Bliss and others.

CISM has thickness on the grid g1 and velocity on grid g0

CISM3_g1_GrIS_multigrid_generater_nc.m

CISM3_g0_GrIS_multigrid_generater_nc.m

CISM3_g1_AIS_multigrid_generater_nc.m

CISM3_g0_AIS_multigrid_generater_nc.m

Will generate a number of grid description files for use with the cdo remap command (https://code.mpimet.mpg.de/projects/cdo).

The resulting 'af' files can be used to compensate the grid projection error. Multiply 2D gridded variables with 'af' before spatial integration, summation or averaging.
