+=== PARAM/config.def_preind ===
+Double check whether in PARAM/config.def_preind the aerosol setting is as follows:
+{{{
+aer_type=preind
+}}}
+All other settings are set to _AUTO_ and should thus be automatically taken into account. For the pre-industrial run only the natural aerosols are used and the regridded data can be found at /ccc/work/cont003/dsm/p86ipsl/IGCM/BC/ATM/LMDZOR/LMD128118/AR5/HISTORIQUE/aerosols_11YearsClim_1860_v5.nc. In COMP/lmdz.card some of the aerosol settings can be manually set (see below).

 More details on the settings of COMP/lmdz.card are given on [http://forge.ipsl.jussieu.fr/igcmg/wiki/platform/documentation/modeles/LMDZ] section 5. For the new physics, set in COMP/lmdz.card

-We can choose from 9 aerosol groups which aerosols we want to account for during the simulation. 6 means that all 9 groups will be used. Activating ok_ade and ok_aie implies that the model accounts for both the direct and indirect effects of aerosols. Because we run without INCA, the aerosols are coupled and aerosol_couple is set to n. For ozone it a day time climatology, a night time climatology or both (=2) can be used. cdnc stands for cloud number count. The path of the aerosol files is also specified in COMP/lmdz.card (see below). For a more detailed description of the these aerosols settings have a look at [http://forge.ipsl.jussieu.fr/igcmg_doc/wiki/DocImodelBlmdz#Informationabouttheaerosolradiativeforcing].

As we are not sure which information is read first, i.e., the PARAM/config.def_preind or the COMP/lmdz.card we don't want to take the risk that the pre-industrial settings get overwritten and so we commented-out the setting in the COMP/lmdz.card.

 Activate 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')
