There is a problem with the model output

[weixinyu]

Dear all
When I run the model, I define the output variable inside user_nl_clm hist_mfilt = 12, hist_nhtfrq = 0, I want to output the yearly average data, and I set history_n=1,history_option=nyears in drv_in, but my final result is very messy, it shows that clm2.h0 is the yearly average but cpl.hi is the monthly average, and I don't know what to do here! I don't know how to set it here. I have the following questions
1、I want to output the yearly and monthly average result, how should I set it in user_nl_clm and drv_in?
2、I want to define the output variables in user_nl_clm, but I don't know what the abbreviations of the output variables stand for, where can I find this content?
I've put a picture of the output below and would appreciate a definitive reply, thank you very much!

hist_mfilt=12 and hist_nhtfrq=0 won't give you yearly average data, it will give you monthly average data with 12 months per history file.
If you want yearly average data you'd do something like hist_mfilt=1, hist_nhtfrq=-8760, where 8760 is the number of hours in a year.
You can find a list of output (history) variables in the User's Guide:
