 - Same for CTLCM6F
 - CTLCM6G and CTLCM6H (IPSLCM6A-VLR_rc0 with new water routing scheme and p_magic = -0.01) and piControl2pm01 (p_magic = -0.01) show a reduction of the error on the 2m-temperature (tas) of around 15%, very likely associated with the adjustment of albedo (p_magic = -0.01)
-- For those simulations, we also note a degradation of the LW up (rlut and rlutcs) between 5 and 10% (greater than the variability among the seasonal cycles of piControl2), probably linked with the p_magic ; in the same time, the SW gets significantly better (around 5%)
+- For those simulations, we also note a degradation of the LW up (rlut and rlutcs) between 5 and 10% (greater than the variability among the seasonal cycles of piControl2), probably linked with the p_magic (mainly concerns the tropics, not shown); in the same time, the SW gets significantly better (around 5%)
 - For CTLCM6G and CTLCM6H, we also see a slight degradation of the zonal wind at 10m (uas), of the same order as the LW ; looking at the RMSE tables for the different seasons and regions, we can see that this degradation mainly concerns the tropics (-20/20°N) and the extra-tropical southern hemisphere
 - For the other variables, the results do not show significant differences between piControl2 and IPSLCM6A-VLR_rc0 (with the new water routing scheme and p_magic = -0.01, simulations CTLCM6G and CTLCM6H)

 Conclusion:
 - the evalution metrics of the seasonal cycle of IPSLCM6A-VLR_rc0 with the water routing scheme of CM5A and the same p_magic are similar to the ones obtained for piControl2. This suggests that the model is the same.
-- the new water routing scheme and the tuned p_magic produce a climate that is in better agreement for IPSLCM6A-CLR_rc0 compared with IPSLCM5A-LR for tas and the SW; we note a degradation of the LW and the zonal winds
+- the new water routing scheme and the tuned p_magic produce a climate that is in better agreement for IPSLCM6A-CLR_rc0 compared with IPSLCM5A-LR for tas and the SW; we note a degradation of the LW and the zonal winds; with the new water routing scheme and p_magic = -0.01, we can say that IPSLCM6A-VLR_rc0 is not the same as CM5A-LR. Further assessment is needed to understand what's happening with the radiative variables.
