GfsVariableFiltered defines a new variable obtained from filtering spatially an existing variable.

The spatial filtering is done by taking the average of the four corners (resp. eight corners in 3D) values in each cell. The corner values are themselves obtained by averaging the centered values of the corner neighbours.

The syntax in parameter files is:

[ GfsVariable ] NAME NITER

where NAME is the name of the existing variable to be filtered, and NITER is the number of times the filtering operator should be applied. NITER must be strictly positive.
