The three scripts
1) preprocess.bash
2) mkpert.R
3) postprocess.bash
can be used to generate as many perturbed versions of the Drakkar Forcing Set 5.2 (DFS5.2) respecting the temporal and spatial covariances of the eight variables of the forcing.
The generation of perturbations is based on M. Meinvieille's thesis (http://www.theses.fr/2011GRENU053)

for more information about the strategy to create the perturbations.
