\noindent 
This post-processor generates input files with gridded model parameters for
the Grid Analysis and Display System \citep[GrADS,][]{man:GrADS}. 
%This graphical software can be obtained from http://www.iges.org/grads.  -- website no longer valid
Although GrADS can also work with GRIB files, the present preprocessor is preferable,
as the data file also gives access to a land-sea-ice map.
