+=== Procédure pour faire une simu xxx-rad ===
+
+C'est une simu où seul le rayonnement voit le CO2, la végétation et la biogéochimie marine voit une valeur fixe (en général préindustrielle) de CO2. 
+
+1/ In COMP directory you need to modify orchidee.card and set the variable as follows:
+{{{
+FORCE_CO2_VEG = y
+}}}
+The consequence of that flag is to have a CO2 concentration value in ORCHIDEE different from LMDz
+
+2/ In orchidee.driver, you need to impose a CO2 concentration value different from the one of LMDz, by adding the following 4 lines.
+{{{
+# CO2 forcing for the current year
+ IPCC_CO2=la_valeur_preindustrielle_en_ppm
+echo '(ORCHIDEE) ATM_CO2='${IPCC_CO2}
+IGCM_comp_modifyDefFile blocker orchidee.def ATM_CO2 ${IPCC_CO2}
+}}}
+
+3/ pisces.driver
+here you need to impose a CO2 concentration value different from the one of LMDz, by commenting 4 lines and adding 3.
+{{{
+#IGCM_debug_Print 1 'Update atcco2 in namelist_pisces_cfg with same value as for LMDZ'
+#LMDZ_CO2=$( lmdzgrep2 co2_ppm config.def )
+#IGCM_debug_Print 1 "LMDZ_CO2 : ${LMDZ_CO2} "
+#IGCM_comp_modifyNamelist force  namelist_pisces_cfg atcco2 ${LMDZ_CO2}
+IPCC_PIS_CO2=la_valeur_preindustrielle_en_ppm
+echo '(PISCES) atcco2='${IPCC_PIS_CO2}
+IGCM_comp_modifyNamelist blocker  namelist_pisces_cfg  atcco2     ${IPCC_PIS_CO2}
+}}}
+
+4/ In the PARAM directory you need to modify orechidee.def.CWRR and set the variable as follows:
+{{{
+FORCE_CO2_VEG = y
+ATM_CO2= _AUTOBLOCKER_  
+}}}
