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 |

| A list of possible history file variables can be found here:CAM-chem History Fields You can find the possible history fields for your own model build by looking in a log file for your setup simulation and searching for "MASTER FIELD LIST". |

It is possible to save output along a time-varying track to match aircraft or satellite observations using the 'sathist' namelist variables. The user must create a netcdf file with the time, latitude and longitude of the desired track and the model profile is saved for the closest locations for the closest timestep(s). If sathistIf sathist_ntimestep and sathistand sathist_nclosest are set to 1 only the closest profile in time and space will be saved. If values greater than 1 are used, the user can interpolate the output to the actual observation location. As many variables as desired can be specified in the 'fincl'; when the file gets too largeto the value specified in 'sathist_mfilt', a new file will be automatically started. NOTE: the aircraft output file is NOT automatically copied to your 'archive' directory at the completion of the run.
