The history files (those that contain model output) can be defined in the user_nl_cam file under the finclX namelist variable, where X may be 1, 2, 3 etc. up to 9. Each 'finclX' will tell the model to write a new file that includes the specified variables. Recommended procedure is to keep fincl1 as the default, because this tells the model to write out month average values of all species that are needed for the automated diagnostics. Therefore, best practice is to write your own history files beginning with fincl2 onwards. 

Example:

Adding the following species to user_nl_cam will write out files with a h1 suffix.

The temporal resolution of the output files is also specified via the user_nl_cam:

Code Block
languagetext
avgflag_pertape     = 'A','A'
mfilt               = 1,4
nhtfrq              = 0,-6
