I am having a problem seeing a solar cycle response in the stratosphere, notably in the upper stratosphere, where it is typically seem in observations and models. Here is what I did in my run.
I ran an 1850 control simulation for 200 years. The only two things I changed for my run are that:
1. I used as input an sst dataset from an 1850 interactive run that was run for 200 years
2. I input solar_parms_file and a solar_data_file by repeating 4 solar cycles for 200 years
When I analyze the output, I do not see a 0.5 K temperature change at the upper stratosphere, which is weird. Attached is the tropical average (25S to 25N) temperature change as a function of altitude, found using a multiple linear regression, where I used the 255 nm irradiance and Nino 3.4 index to fit the data at each level. I also get these weird wiggles in the mesosphere and above that makes me believe something is wrong with how the model read my spectral irradiance data. I set solar_data_ymd to 101, the start date of my model, and solar_data_type = 'serial'. Is there anything else that I need to do?
Any help is much appreciated!
