Dear Community,

I would like to remove the cooling period produced by the _EN4\_1995-2004\_init.nc_ file during the period 1960-2000. I have not managed to create working 1960 conditions for EN4, so I was considering running consecutive 10‑year cycles to produce a 1960 restart file. However, I am not sure how to configure Cylc to achieve this.

In this case, the initial time should remain constant, and the restart file should always be the same. If I run the model starting in 1960, the restart file should always correspond to 1970. Hopefully, after 50–100 years of cycling, I should obtain a stable ocean temperature field. Thanks in advance for your help.

Best regards,

Estanislao
