    5757#### Use SST of a coupled simulation without correction of anomalies #### 
    58 Identify the time series for the simulation you want to use. Use the tsol_oce variables for the surface temperature (SST) and pourc_sic for the sea ice concentration (SIC). The variables must be monthly outputs of LMDZ. 
    59 For example, the files for the IPSLCM5A rcp4.5 simulation are located at CCRT :

    65 You can choose to work with annual variability or with a climatology.

     67 * Annually-varying files (for this case you will use the experiment CREATE_amip)  
    6868Divide the time series into annual files. Use cdo to divide them into annual files with 12 timesteps in each file:

     81Note that in this simple example, you may get some inconsistencies between the SST and sea ice fields. Be cautious!  
    8282#### Use SST of a coupled simulation with correction of anomalies #### 
    8383SST can be corrected with the difference between an AMIP reference SST and a reference SST from a coupled simulation. These two references must be on a same period. [[BR]]
