     189Activate nudging by setting ok_guide=y and add the path to the nudging files in BoundaryFiles section List in lmdz.card. (the French for 'nudging' is 'guider')

     194ERAI nudging files for wind (u and v) have been interpolated to the zoomed grid using the method described here : ​[https://forge.ipsl.jussieu.fr/igcmg/wiki/platform/en/documentation/I_modeles/B_LMDZ#Interpolationofnudgefiles]. If you are not using a zoomed grid that has been used previously, you will have to do this yourself. The years 1870 to 1899 and 1980 to 2011 have been prepared for the 128x118 zoomed grid and are stored at /ccc/work/cont003/dsm/p86ipsl/IGCM/BC/ATM/LMDZ/LMD128118/NUDGE_FILES/ERAI.

     196We still need to tell the model which nudging files it should use. This requires a change to COMP/lmdz.card so that libIGCM knows to copy the files before the run. Note that here we substitute the argument ${year} by 1860 so we will use the same wind fields during the 20 years of the experiment.
