    4141The following, further, changes were made to the COMP/lmdz.card: 
    4242 
    43  (1) Specify in the list of parameter files that the BC should be based on the predefined present day settings. These settings contain the TOA solar incoming radiation, atmospheric CO2, CH4 and N2O among other settings. Have a look in PARAM/config.def_preind to get a better idea of these settings. 
     43 (1) Specify in the list of parameter files that the BC should be based on the future settings (need to be compiled from rcp45 simulations/settings). These settings contain the TOA solar incoming radiation, atmospheric CO2, CH4 and N2O among other settings. Have a look in PARAM/config.def_preind to get a better idea of these settings.

    4747 (2) In the DRIVER/lmdz.driver it is specified that in the absence of the Oasis coupler, which is the case for LMDZOR, the ocean is forced. Hence the need of SST and sea ice files for all years in the experiment. These cyclic files created above have now to be used in COMP/lmdz.card. Therefore, change the boundary files as follows and note that the tsol and pourc_sic files should be renamed as histmth_sst.nc and histmth_sic.nc (for more options see http://forge.ipsl.jussieu.fr/igcmg_doc/wiki/DocImodelBlmdz):

     63Keep the default setting for solaire (1366.0896 Wm-2). Change the settings for co2_pmm = 0.5384E+03, ch4_ppb = 0.1576E+04, N2O_ppb = 0.372E+03, CFC11_ppt = 3.2E+01, CFC12_ppt = 0.185E+03.

    6465Now the ELI-128x118x39-2010 can be launched. It takes about 70 seconds per year so in this example it will take over 30 minutes to complete this 30-year job

    7970== The future experiment == 
    8071Where for the BC run, an LMD experiment was copied, we now have to copy a LMDZOR experiment. We haven't tried whether LMDZ/clim BC files can be combined with LMDZOR/amip experiments but to keep it simple we propose to be consistent and thus combine LMDZ/amip BC files with an LMDZOR/amip experiment

    9486Make sure to use a begin and an end date that falls within the ELI experiment. Given we want to simulate the equilibrium climate with the surface we should provide an initial condition of the vegetation. As an initial condition we use the restarts of an off-line simulation. Remember to use a restart for both the SRF and SBG component!
