 Keep 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.
 Now 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

 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. Similar to the pre-industrial run in which we only used the aerosols of 1860 we will now only use the aerosols of 2000 to avoid adding more variability to the present day runs compared to the pre-industrial run. Because we want to calculate the net climate effect of both biogeochemical and biophysical effects of forest manangement and land cover change, we have to recalculate the atmospheric CO2 concentration for the different treatments. To do so we first applied the BERN2.5 box model to account for the equilibrium between the atmosphere, the land and the oceans (thus the reason why ~40% of the emissions stay in the atmosphere). Following we converted this CO2 uptake/release into a change in atmospheric CO2 concentration. Finally, this change was subtracted from the present day atmospheric CO2. Note that $$$ below should be BC, BCF, BCL or BCLF depending on the experimental treatment.
