- * For running : Add nudging by setting ok_guide=y and add nuding files in !BoundaryFiles section List in lmdz.card. Nuding files must be interpolated to model grid as well as aersolols files. 
- * For the moment you have to deactivave aersolos as they are not interpolated yet. Remove them from List in lmdz.card and set following in beginning of lmdz.card :

+== Aerosols ==
+The aersols have to be interpolated to the zoomed model grid. The years 1990-2000 for HISTORIQUE run has been done. They are found at default place (no need to change in lmdz.card for these years) : /ccc/work/cont003/dsm/p86ipsl/IGCM/BC/ATM/LMDZ/LMD128118/AR5/HISTORIQUE

+For other periods, it is possible to deactivate aerosol forcing. To do so, remove the lines containg aerosols_ from List section and change in lmdz.card to the following :

+ok_ade=n
+ok_aie=n

+NB : read_climoz=0 will also deactivate the reading of ozone. Ozone is regridded by the job LMDZ/CREATE_ so this is not necessary to deactivate.
