CESM1.2.0 B compset 'ccsm_startup' ICs source

[cnrwil004@myuct_ac_za]

We ran CESM1.2.0 with "B" component set using the default initial conditions (ICs) for all components. I am in the process of writing up a Master's thesis based on results obtained from these runs and I would like to describe and appropriately reference the ICs used for this set-up of POP2, if possible. I have looked at other studies that have used a similar set-up of CESM1/CCSM4 and the CESM and POP2 documentation and POP2 FAQ, but it is not clear to me which Levitus or PHC2 climatology is used in the default start-up in the CCSM4 configuration of CESM1.2.0. Thank you in advance

Please could you attach the file env_run.xml. Thank you.

Thank you for the reply.I have uploaded a sample env_run.xml file; I have tried to reset variable values to what they were likely to have been at the initialisation of the first run. I have also tried to remove references to particular directories that are likely irrelevant. I hope that is useful.

I wanted to look at the env_run.xml to make sure the run starts from Levitus. It does. In the default configuration, some compset starts from a spunup ocean, other starts from Levitus. I wil check with the oceanograpghers to get more info about the dataset.

The details of the ocean model initialization are given in Danabasoglu et al. (2012, J. CLimate, v25, 1361) -- see section 2. You can also take a look at the Large Ensemble paper by Kay et al. (2015, BAMS, in press). I believe Cecile confirmed that your case started from Levitus T and S and state of rest for the ocean model. So, you can cite Levitus et al. (1998) and Steele et al. (2001).

Thank you for the responce. I am aware of these two studies, I was just not sure whether they used default ICs (which we did), so I was not sure whether our ICs are equivalent to Danabasoglu et al. (2012).
