Problems about compset for CMIP6 piControl and 1pctCO2

[Mikasa]

Hello, I want to do experiments based on the CMIP6 piControl and 1pctCO2 compset. And I found the probably right out-of-the-box compset:



Are the compsets above suitable for my scientific case ? Additionally, I found the following notes on the webpage https://csegweb.cgd.ucar.edu/experiments/public/ .

A pre-industrial control simulation with non-evolving pre-industrial conditions. Conditions chosen to be representative of the period prior to the onset of large-scale industrialization, with 1850 being the reference year. The piControl starts after an initial climate spin-up, during which the climate begins to come into balance with the forcing. The recommended minimum length for the piControl is 500 years.​

Does it mean I have to run the piControl for more than 500 years ? If so, it is really a huge demand for resources and time.

We have already completed the control runs and that data is publicly available.
You should make sure that your system has passed the ECT test before proceeding.
If that test passes these should be the compsets you want.

I have passed the ECT test. The public data of control run does not have the variable we want. So can I just run the piControl for 150 years not 500 years ?

What variable(s) are missing from the piControl that you want?

Thanks you for your reply! Indeed, we want the cpl histoty file of piControl to get the variables like xao_ax_Faox_swdn, xao_ax_Faox_taux and so on. Are they in the public data?

I'm sorry, but it appears the coupler history files we have from the FV 1 degree 1850 control do not contain the fields you want.
