CESM O3 hourly output

Hi,
I am currently using CESM2.1.3 (CAM4, CLM5), FMOZ compset. I want to get O3 hourly output in the hist file and the rest of the other variables in the monthly output (default). I made some changes in user_nl_cam, but I am still getting h0 files as model output and on checking the output .nc file, it doesn't seem to be hourly. Could anyone suggest to me how can I do this? Many thanks.
These are settings added in user_nl_cam:
avgflag_pertape = 'A'
nhtfrq = -1
mfilt = 1
ndens = 2
fincl1 = 'O3'

I am not sure I totally understand your question. If you are wanting to have O3 hourly and the rest of the variables monthly, you will need to have at least two output files as there is only one time field per file.

To have monthly data in your h0 (first file) and hourly data in your h1 (second file), you will set the nhtfrq as follows:
nthrfrq= 0, -1

Then fincl2='O3' and fincl1 will default to the original monthly output variables.

If you want to set the other output variables as well (mfilt, etc), each of them will have two values, one for the h0 file and the second for the h1 file.
