Hi, Team I have run an AMIP-style AM3 simulation with SST+4K. I can confirm that the SST is increased by 4K as expected. I am wondering how this is achieved either in the model source code or configuration? I am asking because I may be interested in changing the magnitude to investigate non-linear …

Hi @qinggangg , In essence, from what I can see, the SST climatology file is being replaced with another that has had 4K added to it. This is all handled by the rose/cylc optional configs. The optional EXPT_SST=“sstp4k” path is defined in ~/roses/suite-id/app/install_ancil/opt/rose-app-sstp4k.conf …

@qinggangg can you give more information on what you have run? What suite is it? Where or who is it from?

Hi @clairecarouge , Sure, sorry for being unclear at the first stage. I have run the alpha release of the ACCESS-AM3, and a sensitivity test by changing SST Configuration in suite conf > Model Configuration from Base SST to SST+4K here: /home/563/qg8515/roses/am3-controlp4k.

Thank you @cbengel I will check how to handle files like qrclim.sst.
