annual primary history files

[nadinsel@uchicago_edu]

Hi, I am wondering how I can change the output frequence of the primary history files for the fully coupled model to annual. The default output frequency is monthly. If I change nhtfrq = -24 and mfilt = 2 in the cam file, I get output files every other day with 1 day everages. However, If I keep nhtfrq = 0 and change mfilt =12, i still get monthly output files instead of annual files with monthly averages. What am I doing wrong? I don't want a second output file, I want to change the primary frequence to cut down on CPU time. Thanks.

You can try setting nhtfrq to -8760 (365x24).  e.g,:nhtfrq=0, the file will be a monthly average nhtfrq>0, frequency is input as number of timesteps. nhtfrq
