How to do sensitivity analysis on solar_const

[Daniel]

I tried to do some sensitivity analysis on solar_const. I used QPC4 and some other component sets with a resolution of f19_19 on CESM2.2.0. I set the solar_const and do 20-years runs. However, the results of global mean TS are always the same 14.7oC with different solar_const values (1361 and 1375). May I ask how to do a meaningful sensitivity analysis on solar irradiation? Any help with this would be much appreciated!

The QPC4 compset is an aquaplanet compset in which you prescribe the SST. In aquaplanet, TS=SST. This is the reason why TS will not vary. Maybe you could look at TREFHT or at the temperature at another level.

Thank you, Cecile! I have checked the TREFHT, the 20-year results are still nearly the same (13.757 and 13.758oC) for different solar_const values (1361 and 1375). May I ask which component set is the best for the sensitivity analysis on solar constant?
