Initial conditions

[Shreya Bhowmick]

Hi everyone,

I am new to CESM. I want to run the compset F_AMIP_CAM5 from 1950 to 2020 using the initial conditions (of all components) from the restart file of B1850C5 or B1850C5CN of the year 1950 and also prescribe the SST from this run. I am using version 1.2.2 as I'll use a Linux cluster and a startup run is computationally expensive. Can anyone suggest where can I get the initial conditions or how can I do this?

Thank you for your time,
Shreya.

You'll need to find a suitable CESM simulation that has restart files for 1950. You can use the CESM experiment database to look into such existing simulations. Often these simulations are used for later model versions for starting the model up so are part of the inputdata files (for example for CESM2 under cesm2_init).

Is there a reason you need to use 1.2.2 rather than the latest CESM2 release version?

Thank you for the reply. Currently I do not have access to a linux cluster. I am trying to port CESM 1.2.2 as per the advice of my supervisor in a linux server having 24 processors each having 2 threads in my university. There is no system administrator.

Here's a link to CESM experiments. Hopefully, you can find something suitable to start your simulations from:

Thank you so much.
