+The aerosols have to be interpolated to the zoomed model grid. The years 1980-2000 for HISTORIQUE run version _v5 have been done. They are found at the standard place : /ccc/work/cont003/dsm/p86ipsl/IGCM/BC/ATM/LMDZ/LMD128118/AR5/HISTORIQUE . You need to change _v3 into _v5 in lmdz.card to use these files.

+It is also possible to deactivate aerosol forcing. To do so, remove the lines containing aerosols_ from the List section and change lmdz.card to the following :
+{{{
+# manage radiative aerosol effect and ozone 
+flag_aerosol=0
+ok_ade=n
+ok_aie=n
+aerosol_couple=n
+read_climoz=0
+ok_cdnc=n
+}}}
+Note that read_climoz=0 will also deactivate the reading of ozone. Ozone is regridded by the job LMDZ/CREATE_ (as are some other boundary conditions such as SST, sea ice, ...) so this is not necessary to deactivate.
